Holy Sh*t Moments #3: Enhancing the Copper

If you've been following my blog or my web site for any length of time, you know that my all-time favorite tweak is the Stein Harmonizer system. It psychoacoustically expands the boundaries of one's listening environment (the room and space sound bigger than they are), creates silky smooth mid & high frequencies, and reveals subtle textures and information like nothing else I have used to date.
A Stein Harmonizer - Still my favorite tweak.
It's also really expensive to do properly. You need at least 2 Harmonizers, then there are the Blue Diamonds to place atop the speakers, and the blue suns to disperse about your room that adds even more to the effect. It's amazing when implemented properly.

An Opportunity To Experiment

I had lent out my Harmonizer system in late September, and it would not be returning until right before RMAF. I missed them terribly while they were gone, but it also gave me a chance to experiment with my other tweaks, trying to recreate the effect of the Harmonizer system I had lent out.

The net result of the absence of the Harmonizers was the DIY tweak consisting of .1875" and .3125" copper rods along with copper cups was proving to have a mind bogglingly good effect on the system. Similar to the Stein in that it made the room appear larger sonically, also enhancing dynamics and resolution. It was not as powerful as the Stein, but still pretty darn good on its own.

I didn't have a whole lot of time to see how the copper interacted with my other room tweaks with RMAF approaching, as I had removed all other tweaks from the room and had them packed away. But that would allow me to do one of my favorite things once I returned from the show to a "tweakless" room. 

Starting With A Clean Slate

I like removing all of my tweaks and disassembling my system every few months, it serves as a sanity check (along with having a group of audiophile friends whos ears I borrow once in awhile). I get to re-introduce tweaks one at a time to asses their effect, and synergy with the other tweaks.

So, returning from RMAF with copper "sculptures", copper cups, Bybee QP's, and the Stein Harmonizer system, and some other tweaks that were lent to me by my friends at Stillpoints (more on that later), I began re-introducing the tweaks.

The Experiment

Starting with the Copper cups and sculptures. I ended up with 2 .1875" rods centered in front of me, 2 .1875" rods off to the left and right of my listening chair, and 1 of the larger .3125" rods behind me. This had a pleasant, warm and rich tone with, nice dynamics a fairly holographic soundstage. Nice but not the Steins.

I had several Stillpoints Ultra 5's and Ultra 6's to experiment with as well as a new active grounding conditioner from Telos. The short story here was the Ultra 5's and 6's shocked me with the improvement in high frequency clarity, transient attack and dynamics they allowed my system to reproduce with such ease. The Telos worked in addition to the Entreq ground boxes I had in place already. Further reducing the noise floor by creating an active reference ground. More detail without becoming sterile.

My system was starting to get to a very good place, with focused imaging, incredible dynamics, and a pretty wide soundstage. If I had never had the Harmonizer system, I would be very happy, but I knew I could achieve more..

The next introduction would take more time. It was re-introducing the Bybee Quantum Plugs. This has to be done over time because the Quantum Plugs need to charge, or settle in. It takes a day or two. I started with two at the back of the room. It's a long room and they were roughly 20' from my listening chair. I let them settle in overnight and came in to listen the next morning. This was a subtle, but pleasant improvement in the wrap around effect the soundstage was producing. I was getting more ambient information, decays were longer, and the immersion into the soundstage was more pronounced.  Moving forward cautiously, I only added 1 Quantum Plug. I placed it as close to the center along the wall behind the speakers as I could.

to get the colorful look.
The next morning, the front to back, as well as side to side aspects of the soundstage really began to fill in. This was about 80% of the Harmonizer system's effects, especially when implementing the large 12 oz copper cups in the center behind the speakers as well. The speakers had disappeared, leaving a wrap around soundstage, with focused imaging and fantastic dynamics. If I had never heard the Harmonizer system, I could stop there and be extremely happy.

So there you have it. My "Poor Man's Harmonizer System". It consists of the following:
  • 6 .1875" copper rods, placed in 18" long 4" x 4" boards that I had sanded and finished.
  • 1 .3125" copper rod in a finished wooden board like above.
  • 3 Bybee Quantum Plugs - You may only need 2, depending on the size of your room.
  • 2 large 12 oz Sertodo copper cups.
  • 2 small 2 oz Sertodo copper shot glasses.
This will get you 80% or so of the effect of the Stein system, and cost under $600. 

Some things to note

  1. More is not necessarily better - Too much copper, or too many QP's and the sound gets a little artificial. Move slowly, take your time. Start with the copper first, then start adding QP's.
  2. Placement of the QP's does not have to be exact. The front and back of the room placement is more important than being placed exactly at the center of the wall they are plugged in to. If you are concerned about this at all, buy a 3 prong extension cord for the QP. Then you can place it precisely. 
  3. The copper rods work best near a wall. These too do not necessitate exact placement. If you have a choice between placing them exactly but far from a wall or slightly off but near a wall, near a wall is the way to go.
  4. If you have a Harmonizer system already, don't sell it!  The rods and the QP's will work with the Harmonizer products really well. Think of it as having more tools to treat your room. I use 2 Harmonizers, 2 blue Diamonds, and 3 Blue Suns along with the copper and QP's.  I found this to provide the best blend of dynamics, texture, tone and resolution.
