How to Supercharge a Bybee Quantum Purifier

Bybee Quantum Purifiers have been a mainstay at TweekGeek since it's inception. Jack Bybee has established himself as the consummate tweak meister with these little devices that have performed sonic miracles on hundreds if not thousands of audio systems worldwide. They have evolved over the years, and are available in a DIY series of Purifiers that one can use for AC, speakers and line level, as well as a full line of adapters, and finally one of the best power conditioners on the market today.

I am about to walks you through how to "tweak" the large Bybee Quantum Purifier to enhance its performance. This applies to the large copper Purifiers as well as the large gold Purifiers.

What you will need:
  • 3/4" copper tubing. You can buy pre cut couplers, or if you want to cut a more exact length, just buy a length of tubing and cut to size.
  • Stillpoints 1" ERS Tape. This tape absorbs and diffuses RFI. Many people use it inside components as well.
  • Bybee Purifiers (of course)

How to assemble the Bybee Supercharger:
  • Begin by determining what length of tape you will need to wrap around the Bybee purifier in order for it to fit fairly snugly inside the 3/4" copper tube. Oddly enough you will not be removing the backing on the ERS tape. Why? Because ERS is more effective with a dialectric between each layer. It would actually be less effective if you took the backing off and stuck the layers together.

  • You will need 2 identical lengths for each Bybee. It takes 2, 1 inch pieces of ERS tape wrapped side by side to cover the entire length of the Bybee.

  • Once the Bybee is wrapped, insert it into the copper tube.

  • You can wrap the outside of the copper tube with an additional layer of ERS tape.

  • cover the tube with shrink tubing, or electrical tape so there are no extra conductive surfaces, and you have a supercharged Bybee Quantum Purifier!

The end result is you have an even more transparent sound than with a stock Bybee. When you use the Gold Bybee for the SuperCharging, you approach the level of the super expensive, Super Effect purifiers. The kind used in the Super Effect Speaker Bullets that retail for $4200, and are not available to the DIY market.



  1. Hi Mike,

    I found your Bybee Supercharging atricle to be both highly enlightening and very familiar. For the last 3 years, I have used both Bybee's and Z-Sleeves combined on every power cable, speaker, IC, digital and video cable in my system. The makeup of the Z-Sleeve, copper tubing and ERS mirrors that of your tweak but yours can be done at a much cheaper cost and w/o the hassles encountered using a bulky Z-Sleeve. But I have found that when able to actually cover an inline Bybee with a Z-Sleeve, the effects of the Bybee in that application is much more pronounced. For me, I love the sound stage depth created by extensive use of this combination thoughout my HT/music system. I would highly recommend your diy tweak be tried on any video,IC, digital, speaker or power cable.


  2. Hi Mike,

    Can copper sheets 36 gauge be used to substitute the copper tubing? Also why do you need to wrap the large purifier with extra ERS paper? "Large Quantum Purifiers are specially shielded against external RFI and EMF noise by the use of ERS Stealth carbon fiber" Thanks

  3. Hello Satfrat,

    Thanks for the validation. Yes this is similar to a Z-sleeve, but they use a more measured approach, plus some proprietary tricks to make the Z-Sleeves even more effective than what I do.

  4. hello Tianci,

    Yes copper sheets can be used, but there must be a sufficient overlap of the sheeting so as not to allow any emi/rfi in or out. We have found that even more ERS material than what a stock Bybee already employs provides audible sonic improvements.
