Roon Core and Innuos Streamers - To DSP/Upsample or Not?

I get a lot of questions regarding the capabilities of Innuos Music Streamers and Roon. I am going to attempt to address some of them now, and will probably continue to add to this blog as more questions come up.

How Does Roon Work With An Innuos Streamer?

Great question, and for this we need to first go to the Roon web page that gives a brief overview of how Roon Works.

The great thing about Innuos streamers is the fact that they can run Roon Core AND act as the Roon Streamer. You add the (USB Audio Class 2 capable) DAC of your choosing and away you go. Sort of...

What if I Want To Do Upsampling Or DSP? Can I still Use The Innuos As A Roon Core?

As my parents taught me, "all things in moderation". The same goes for DSP and upsampling.  Most Innuos models run the Intel Quad Core N4200 chip. 

Zen Mini MK3: 4 GB of DDR3 RAM
Zen MK3: 8GB of low voltage DDR RAM, with 4GB dedicated to RAM playback
Zenith MK3: 8GB of low voltage DDR RAM, with 4GB dedicated to RAM playback
Statement: 8GB of low voltage DDR RAM, with 4GB dedicated to RAM playback

From the Roon Optimized Core Kit Knowledge Base, they recommend 8GB of ram and a 128GB SSD for heavy DSP or large libraries.

From this we could infer that the Zen Mini is probably not a good candidate for anyone interested in DSP, upsampling, or large libraries. The others are probably okay for moderate DSP and upsampling.

We could also infer that the Zen, Zenith and Statement could handle moderate DSP and upsampling. I say moderate because of the Intel N4200 chip is only quad core and may start sounding worse when tasked too heavily. They may not play super hi rez formats like DSD with upsampling and DSP. So the rule here is PCM only for sure, but DSD? Maybe not.

Here is a link to a great comparison site for PC components. It will allow you to compare benchmarks of CPU's, SSD's, RAM and more.

My Soapbox on DSP: Bottom line. Less is more with DSP. Use broad, low Q filters, and minimize DSP on high frequencies to prevent comb filtering. Use mechanical acoustic treatments to tame resonances/reflections and take the time to properly position your loudspeakers before going to the digital toolbox.

Conclusion (so far)

With this information in mind, how should one best use their Innuos Streamer? In my opinion, minimize the use of DSP and upsampling, and use your Innuos as a Roon core and a streamer. This creates the shortest signal path for the data and ensures that that path is optimal as far as minimizing noise or interference.

As always, use your ears to guide you. If you use DSP or upsampling with ANY Roon core there may be tradeoffs. Why? Because you are taxing the processor with more tasks. Sometimes the negatives outweigh the benefits when you start demanding more from the CPU.

Placing Bybee iQSE V2's Part II: The Listening Environment

In case you missed it, here is a link to Part 1: Placing V2's On Speakers

There is no doubt that placing the Bybee V2 on the loudspeaker baffles enhances the resolution of your loudspeakers as pointed out in the June StereoTimes article.
Bybee V2 on the front baffle of one of my loudspeakers.

It took me weeks of listening however to figure out that this affected the soundstage in my system and room. The V2's it seemed were almost too powerful on the front baffles of my speakers. This led to great resolution, but placed too much emphasis (for my taste) on the location of the speakers themselves. The resolution was astounding, but the speakers tended to have less of a disappearing act as a result of having the V2's on the front baffle.

My listening preference is for the location of the speakers to be undetectable sonically. leaving in it's place a soundscape that extends beyond the boundaries of the room. With a setup like this, and a good recording, I am transferred to the space where the recording is made.

This post came out of my experimentation with placement of the V2's in my listening room. The goal of this weeks long experiment was to have the resolution the V2's brought to the system and the soundscape I desired. It may not be your cup of tea, but for those who have tried the V2's on the front baffle of their speakers and had similar findings to mine, this might be the ticket for you.

So as I mentioned above, I felt the V2's might actually be a bit too powerful for speaker baffles, I wanted something slightly less powerful. Dark Matter Technologies products fit the bill in this regard. They have a similar, but less powerful effect than the V2's, and work very well together with them. I found the Qubes to work well in conjunction with Wormhole Dots, to get the effect I wanted without drawing too much attention to the speaker locations. More on that later however.

We found through much experimentation that careful placement of the Bybee iQSE V2 in the listening room, along with the help of the new Dark Matter Dots and Qubes can yield an immersive, natural soundfied with the sonic characteristics that the Bybee iQSE V2's are known for.

For those of you not familiar with the Bybee V2, below is a photo.

The Bybee IQSE V2

The new DMT Wormhole Dots are thinner, more attractive and way, way more powerful than the original Dots. We found them to work best on AC, on loudspeaker baffles, and as a room treatment.  They are pictured below.
The DMT Wormhole Dot. $99 each.

The Canvas

My listening studio is about 15' wide and 25' deep. Towards the back of the room at about the 15 foot mark, the room opens up another 5 feet wider to accommodate a kitchenette, and further behind that is a set of stairs leading down to the ground level.

The listening studio
The ceilings are 8' high and the room has extensive treatment with Vicoustic absorbers and diffusers. It is well optimized to get the most out of a well placed pair of speakers.

Below are our results after much placing, removing, and evaluating the V2's over several weeks.

Placement. One Step At A Time

Keeping in mind that the V2's aren't cheap, we have broken down our ideal setup into steps, so that you can add V2's as funds permit. It only takes 8 to get the sound we have alluded to. You can add more, and it will only solidify and intensify the effect. I had up to 12 in my room at one point, but one can get 90% there with only 8.

Step 1: Centered on the wall behind the speakers
If you only purchase a single V2, this is THE place to try it first. This will add depth, strengthen the center image, and also have the sonic attributes described above.  Adjusting the height of placement affects image height. I like this V2 at about 65" off of the floor.

Step 2: The corners are THE key
Since the V2's work on the nitrogen component of our atmosphere, and sound tends to really bunch up in the corners of a room, it makes sense that they would be really effective here. The next 2 V2's (2 and 3 respectively) in the placement went into the corners where the ceiling meets the side walls and wall behind the speakers.
V2 placed in the corner behind one of the speakers. Each corner behind the speakers were treated.
V2's 4 and 5 were placed on the base boards just off the floor in the same corners behind the speakers. This really added to the sense of soundstage depth, height and width.
V2 placed in the lower corner of the listening room, behind the speakers. Surprisingly, this placement created a very significant improvement in soundstage height, width and depth.

The pattern the placement of V2's created made an X on the wall behind the speakers. With one V2 at each end of the lines making the X, and one approximately at the intersection of the lines. I say approximately because by adjusting the height of the center V2, you can adjust image height. I ended up with the Center V2 about 65" off of the floor.

With the X pattern, the depth of image was greatly enhanced, vocals and lower frequencies sounded more open and natural.
The X pattern created by the V2 placements. 

Step 3: Behind your listening chair

The 6th and 7th V2's were placed behind my listening chair. I have a corner off to my right, and one naturally went there. The fourth V2 was on the ceiling behind the listening position and off to the left. Essentially equidistant to the V2 that was in the corner to behind and to the right of my listening chair. I had no symmetrical corner to the left of me, so this set up the boundaries of the soundstage and kept it balanced. Adding the V2's behind my listening position further depressurized the room, making it feel larger than it is, but it also brought the soundstage around the side walls and behind me. Reverb or hall ambience now filled every corner of the room, and produced a natural, engaging and immersive sound.

Step 4: Completing the X pattern on the ceiling

A V2 centered on the ceiling  can improve image height and the sense of immersion. Again, it is all about balancing the front and rear V2's. My ceilings are 8' high and the distance between my speakers and listening position is a little over 10'.  I find ceiling placement more beneficial in larger rooms with greater distances between listener and speakers. With a V2 Centered on the Ceiling, the soundstage was more immersive, but narrower. It drew the focus back to the center. Taking my cue from the placement of V2's on the wall behind the speakers, I placed 2 more  V2's as near the corner of the listening space as I could. These however were near the ceiling, with the V2 placed behind me at the center was mid way between the ceiling and floor.
If you look closely, you can see the V2 on the ceiling, just in front of the white diffuser. You can also see the V2 centered between the speakers on the window frame.

What The V2/Dot combination Brings To Your System & Room

In every application of the V2, there is a common thread of sonic benefit. Clarity with low level resolution and speed, all with an even tonality. The sound is never forced or mechanical, unless of course that is how it is meant to sound. For acoustic instruments and the human voice, there is an ease and flow to the music that is quite simply more lifelike. Piano music is simply stunning. The complexity of music is there before you, around you, with openness harmonic complexity, dynamic richness. It makes you shut the analytical part of your brain off after the initial shock passes. You sit, for hours, in musical ecstasy.  The effect improves when given more time, taking 24 hours to reach 90% of it's effect and 3-5 days to attain the remaining 10%. For those of you with less patience, the first effects are heard within 30 minutes.

Unlike other brands of room tweaks/treatments, the V2 is fuller, warmer, richer and to my ears, way more natural. 

Placing the V2 in the room can quite literally make the room boundaries sound as if they have vanished, placing you in the recording venue when the recording is well done.


The Bybee V2 is essential to creating an immersive, engaging musical experience in a room. Right up there with Speaker placement, power conditioning, and conventional room acoustic treatment. Dare I say it's a 4th pillar in the foundation of a high quality music system? Yes, I am going to go that far. They are essential, and a must try for any music lover who craves a listening experience that makes them get up and dance, sing, air-guitar, whatever floats your boat. 

Tweek Geek makes trying the V2 in your listening room easy with a 30-Day money back guarantee. If you are curious, start with 8 at the package price of $2600, if they don't work for you send them back for a full refund of the purchase price.

Dark Matter Wormhole Dots & The Power of Power Conditioning

Strange Pattern In System Performance

So here I was, writing a lengthy post on the placement of Bybee V2's & the new DMT Wormhole Dots in the listening room. I was noticing a pattern in my system, and this pattern had been running since I had a system set up in the new Studio. I would get whatever I was working on, be it speakers, tweaks, cabling, I would get it set up and sounding great. It would sound great for a period which would vary. Sometimes a few days, sometimes over night. I would listen again and something wasn't right. Naturally I would blame it on my last change finally settling in. I would make adjustments, or just quit for the day in frustration. Eventually the great sound would return. Sometimes on it's own, or with my efforts. I would enjoy it for awhile, then ultimately something would be off again.
DMT Wormhole Dots

Adressing The Wrong Issue

I suspect this is the case with many of us who try tweaks. You make a change, it sounds great for awhile, then you have a bad listening session and you remove the change or you make a new change. It's an endless cycle, which tells me in many situations we aren't really addressing the right problem.

Back to the story. I was finishing up a post on the placement of the above tweaks in the listening room as room treatments.  That day seemed to be one of the days where the system was sounding off. I sat there, frustrated and uninspired to finish. It dawned on me that we were literally in the heat of summer, and there was probably a large demand for power, and a lot of noise, on the AC grid due to many air conditioners operating.

I had an idea.

It started with placing  a single Dot MK2 on the ethernet cable connected to the wall jack. I had very low expectations as I have tried what seems like hundreds of tweaks and cables on ethernet cables, routers and switches with little to no effect.  Bybee V2's, Stillpoints ERS, various ethernet cable filters, you name it, I've probably tried it.

Interestingly enough, In about 20 minutes, the sound took on a more natural character, with a greater sense of low level detail and 3D-ness. With that in mind I went to work on the whole path. I started with the router, placing a Dot on the ethernet cable connection there, as well as a Dot on the power cord connector attaching to the router. Again, more improvement. Last, for the ethernet connection I treated my Cisco router by placing a Dot on the incoming connection as well as all outgoing ethernet connections and the incoming power connection. After about an hour the sound was considerably more natural and 3D. I was hearing some very fine detail in the high frequencies that were at one time sort of a homogenous blend of highs. This was a surprise because as I mentioned above, nothing else had any sort of effect on this type of signal before.
Wormhole Dots on incoming and outgoing ethernet connections. Not pictured is the Dot on the power cord for the switch.

Well it being summer and us having a parade of family and friends visiting Colorado, I was pulled away from the system for a few days to spend time catching up and socializing. When I returned to the system, it was sounding incredible. Imaging was holographic, the resolution in the highs was still there, and there was a natural character to the sound. 

Moving on to the AC

 I decided to perform the same treatment to parts of the AC path that I hadn't treated with the Dots yet. My studio has it's own sub panel connected to the main houses breaker panel. Taking my experience with treating AC  with products like Stillpoints ERS, I decided to start at the main breaker box. 
Placing a Wormhole Dot on the Breaker feeding the sub panel where my audio circuit was. This had a profound effect.

I learned early on that placing Stillpoints ERS can be counterintuitive. It works better treating AC sources as far upstream as you can. Which in most homeowners cases is the main breaker box where the AC makes it's entry to the house. With this logic in mind,  I placed a Dot directly on the breaker feeding the Studio sub panel. The great thing about the Dots is they are small, light and thin. You can place them directly on the breaker, and still close the door on the breaker panel. 

This had an immediate and very profound effect. More, much more of everything. The 3D soundstage, resolution, naturalness. It was another surprise, perhaps even greater than the ethernet circuit placement. At the very least equal to it.

I then moved to the sub panel, placing another Dot on the 30 amp breaker feeding the circuit for my audio system. Again an improvement, but not as large. 

 All of my power cords already have the "Wormhole" material applied internally, and so did my Dark Matter Stealth power conditioner, so I was done with treating the AC. 
Dark Energy Power Cables have Wormhole Technology Built in.

It's been a week now, and the system has continued to engage me, daily. No moments of feeling that something wasn't sounding right. It's rock solid, grin inducing, goosebump creating sound every time I listen.

What have I learned?

This was an interesting problem. My first encounter I've had where the AC quality fluctuated so much from day to day, even intra-day. I have heard of the power changing from city to city for those manufacturers and dealers that do many audio shows. A few actually bring different power conditioners, and exhibit with the one that sounds best at that particular venue. So yes noise and distortion on power lines is real, it can change from location to location, and can even change throughout a period of time at the same location. No power conditioner is great in every situation it seems. 

So far, the Dots are taking care of what was causing my system to fluctuate in performance at this location. I find it interesting that these tiny tweaks do so much to noise on such high voltage/amperages. But there was no doubt that placing one on the 100 amp breaker feeding my sub panel was a very large gain in resolution, naturalness and the 3D nature of my system.

If I were to start out with some Wormhole Dots today. I would go in this order:
  • Breaker box on the breaker feeding the audio circuit, continuing to each power cord on each component
  • The ethernet "circuit" feeding your streamer
  • The Room in conjunction with Bybee V2's
If you are curious about the Dots, they are backed by our 30-day money back guarantee. You can try them and return them for a full refund if they don't meet your expectations.

They start at $99 each. With discounts for volume purchases.

Placing Bybee iQSE V2s: Part 1, loudspeakers

Bybee V2 below the midbass driver on my loudspeakers
The Bybee V2. One of the most powerful and versatile bits of audio tweakery I have ever had the pleasure of discovering. They are truly universal devices. They can be used on loudspeakers, on power cables, inside components like DACs, amplifiers and power conditioners (we incorporate them on our Dark Matter Stealth power conditioner) and in your listening room.

In this series of blogs, we intend to cover our and some of our listener experiences using these devices in the afore mentioned locations. This is the first in the series, and we will cover the lessons we have learned using them on our loudspeakers. Hopefully some of the things we have learned can shorten the time you will spend experimenting.

What The V2 Brings To Your System & Room

In every application of the V2, there is a common thread of sonic benefit. Clarity with low level resolution and speed, all with an even tonality. The sound is never forced or mechanical, unless of course that is how it is meant to sound. For acoustic instruments and the human voice, there is an ease and flow to the music that is quite simply more lifelike. Piano music is simply stunning. The complexity of music is there before you with openness harmonic complexity, dynamic richness. It makes you shut the analytical part of your brain off after the initial shock passes. You sit, for hours, in musical ecstasy.  The effect improves when given more time, taking 24 hours to reach 90% of it's effect and 3-5 days to attain the remaining 10%. For those of you with less patience, the first effects are heard within 30 minutes.
For loudspeakers, the V2 is especially helpful with tonal accuracy, immediacy, detail, air, space, imaging, and soundstaging.
Bybee V2 between the midrange and high frequency driver.

The Front Baffle

This seems to be a universal, positive placement option. It makes sense if you understand how these devices work on the oxygen and nitrogen in the atmosphere.  Clarity with low level resolution and speed, all with an even tonality.  Some users recommend placing one between the midbass/midrange driver and high frequency driver. Additional benefit can absolutely be gained by adding more; one between each driver, one above the topmost driver, and one below the bottom most driver. Essentially "sandwiching" each driver with a pair of V2's.

In my particular case (so far), I achieved the best results with one centered on top of the speaker, and one just below the 12" midrange driver. My speakers are highly efficient, and use a horn-loaded air motion transformer for 1k on up. AMT drivers are unique in that they force air outward towards the listener by "squeezing" either end of the accordian shaped diaphragm together, rather than vibrating the diaphragm back and forth like a typical driver. The motion of the AMT propels the sound outward with much more force, perhaps making it more sensitive to what the V2 does. In any event, placing a V2 too close to the horn loaded AMT was too much of a good thing. It started overpowering the 12" midrange. With a little experimentation, I found a good balance of not too close, and not too far. 
Bybee V2 placed just above the high frequency driver.

The Top Of the Enclosure

This worked in my particular speaker's case, and may work for yours as well.  Having a larger placement area for the V2 allowed me to tune the strength of the effect. Placing it close to the front baffle had the strongest effect. Placing it further back on the top of the enclosure did two things; It added to the overall air and space of the presentation, while attenuating the effect on the high frequency driver, which in my case was necessary. 
This worked best in my situation. A V2 centered on top of the speaker.

Enclosure Sides

The V2 can actually shape the soundstage. This becomes evident when you start placing them on the top and sides of your loudspeakers.  Want a more spatious sound? Try moving the V2 to the side of the enclosure, keeping it positioned at the same height as it was on the front baffle. Also keep it closer to the front of the speaker. Placing it on the outer facing sides of the enclosure offers a more spacious sound, but it can also hollow out the center image. Placing them on the inside facing walls of your speaker enclosure will focus the soundstage towards the center.  At this point, you are starting to transition from a speaker tweak to a room tweak, and placing the V2 on the walls (our next topic) might be a better option.

In closing. The Bybee V2 can take your musical enjoyment to unimaginable heights. This can be done with as few as two of the devices placed optimally on your loudspeakers. The benefits they produce far outweigh the cost of upgrading speakers, isolation feet, or speaker cables. They are a "must try" tweak for those who have already optimized their speaker placement, room acoustics cabling and power conditioning. We absolutely encourage you to try them, and we fully stand behind the Bybee V2's with our 30-Day Money Back Guarantee.

Which Streamer Is Right For Me?

Choosing an audiophile level music streamer can be confusing. Especially when adding the dimension of feature sets with sound quality. I do not intend for this to be an ultra-detailed breakdown of each brand of streamer Tweek Geek carries, but rather this is a preliminary guide to help one determine which features are important, and which brand offers those features for your needs. All of these products are fantastic and well reviewed. There are sonic differences, but the differences in features are wider and need much consideration when dropping a few grand. We are here to help in that case. If you want to discuss sonic differences, shoot us an email or give us a call.

sales@tweekgeek.com | 303-653-6341

All Streamers

All of the streamers mentioned below have the following features:
  • Roon Ready
  • Stream Tidal, Qobuz, and internet radio
  • DSD capable
Regarding MQA compatibility, all of the streamers will pass MQA, it's up to the DAC in most cases to unpack and play it as MQA. If one is intending to use Roon as the "remote control" software, Roon does have the ability to take the MQA file and convert it to PCM, or pass it through as MQA to the DAC. So technically all streamers can stream MQA for playback to any DAC.

Auralic Streamers 

AURALiC has split their line into two types of streaming products: The Aries G1 and G2 are dedicated streamers only, and the Vega G1 and G2 are primarily DACs, but have ethernet jacks built in so that they can be used as streamers as well. So why bother with the Aries streamers at all? I liken this to the question of separates vs. an integrated component. With the Aries you get a dedicated power supply and more circuitry devoted to the streamer. That and a few other features listed below distinguish the Aries from the Vega line of products.

Vega DACs
  • Built in DAC
  • No Storage
  • Ethernet only
  • Proprietary "Lightning" app can be used instead of Roon
The AURALiC Aries G2 Streamer

Aries Streamers
  • Wireless capable with no additional hardware
  • Airplay capable - great for streaming nearly anything from a browser window. SoundCloud, YouTube, tons of great content.
  • Large front panel display
  • Proprietary "Lightning" app can be used instead of Roon

Innuos Streamers

The unique ability for Innuos streamers to act as server (Roon core) and streamer (Roon endpoint) along with internal storage and a CD ripper make the Innuos products a self contained streaming solution. If it weren't for the wireless network connection needed to connect your remote control (Android or iOS phone/tablet) you could almost do without an internet connection entirely. Of course you may run in to issues when trying to retrieve metadata on CD's you are ripping, but for playback, you could disconnect from the internet entirely.

The Innuos ZENith Statement Streamer
  • Ethernet connection only
  • Run Roon Core AND Roon Endpoint
  • Internal Storage
  • Built-in CD Ripper
Innuos is the only brand Tweek Geek currently carries that does not have it's own controller app. You must use  a third party app like Roon to operate.

Lumin Streamers

Lumin has been in the streaming game longer than Innuos or Auralic. as a result, their product is probably the most mature. Their proprietary app is also very well thought out, and may preclude the need for purchasing Roon. Some units have outboard power supplies, and some have transformer coupled outputs. There are usually a number of digital inputs to choose from as well, so that older DACs, or DACs that have no (or lesser quality sounding) USB inputs.

The U1, and U1 mini are streamers only with no DAC. The D2, T2 and flagship X1 are their newest products.

  • Ethernet connection only
  • Model X1 has an outboard power supply
  • Models D2, T2, A1 & X1 all have built in DACs
    •  As a result, they can stream MQA
The Flaghsip Lumin X1

We hope you found this information helpful. Please visit the Tweek Geek web site, email or give us a call if you need more information on any of these amazing music streamers.

The Dark Matter Stealth Gets A Significant Upgrade

Tweek Geek has been manufacturing Jack Bybee's power conditioner under license for over 10 years now. It has undergone so many changes that it is unrecognizeable from the first conditioner Jack B. produced. In fact the first conditioner consisted of inexspensive wire, three bybee purifiers, a surge protection circuit and 4 Hubbell AC receptacles in a wooden box.

Not only have Jack's original AC Purifiers improved greatly, and I mean GREATLY, but the wiring, receptacles, the addition of other AC enhancing products, advanced filter networks, even the chassis have improved. You wouldn't recognize it sonically or visually.

Every change along the way has brought a significant improvement. We were very content with the performance and up until recently, we weren't sure adding more filtering/conditioning devices to the circuit would improve things. Which brings us to now. We have indeed found 2 simple upgrades added in parallel to the circuitry are worthy of being called an upgrade. Read on to find out what they are.

Dark Matter Stealths in Silver and Black.

Adding The Bybee V2
The Bybee V2 is the latest device to come from the mind of Jack Bybee. It's totally passive, meaning it does not need to be soldered into a circuit to be effective. It is a small device that has a tiny amount of current running through it in order to generate a consistent field effect. That current is provided by 2 watch batteries and is said to have a life of over 20 years. We place the V2 inside our conditioner, after all other series level power filtering and conditioning has been performed, and right before the power goes to the Furutech GTX-D NCF outlets. 

Bybee V2. Ugly, But what it does for the sound will astonish.

Adding Dark Matter Qubes 
DMT stands for Dark Matter Technologies. This is my invention. Jack helped me develop it. It comes in a few different formats, strengths and sizes. From the Qube to the Mandala.  We use the Qubes inside the Stealth. Placing one on each AC receptacle, another on the power inlet, and two more on top of the epoxy box that holds the Bybees and other filter networks. 

The Results
I am not going to post an upgrade to a product unless it is significant. As tempting as it is to make a small change to make something "old" in the audiophile world "new", I can't do that. I want this to be a worthwhile upgrade to owners of the previous generation, and for new owners I want this to create an irresistible value proposition. 

For existing owners looking for a word to quantify the end result of the upgrade, shocking would be the word I would use (no pun intended...). I would explain it like this: Remember the first time you heard what a Bybee Purifier or tweak could do? How it opened up your audible world to new details, and levels of musical enjoyment. It's like that, again...

Breaking it down
I want to be clear on the improvements you will hear over your existing Stealth, or in comparison to the last generation. 

  1. Low level resolution - You will hear more. More low level detail, more expression in a singer's voice or instrument. The resolving power of the upgrade is deep, and musical.
  2. Image density - This was a very pleasant surprise. There is more fullness and solidity to images. It is as if low level phase information was a bit smeared before, but now is totally locked in. You will notice low level phase information you've never heard before.
  3. Soundstage expansion - We usually talk in terms of soundstage width, height, and depth. Now I want to introduce a new term, Immersion. With the upgrades, you become immersed in the sound. It's all around you, enveloping you in blissful music. It goes beyond width, height and depth because the sound is all around you.

Bottom line - In my opinion, this upgrade doubles the effectiveness of the Dark Matter Stealth. I can think of no better way to improve any Dark Matter Stealth owner's system. If you don't own a Dark Matter Stealth, now would be a great time to consider investing. I say with complete confidence that this is one of the best power conditioners on the audiophile market today.
