Synergistic Red Fuse ...

On the basis of David's list above, I would add the following as benefitting from the SR Red and now replaced with SR Black fuses:

Bryston BDP-2
Bel Canto DAC 3.7
Primaluna Prologue Six

I am glad you tried the Synergistic Research RED fuse. As you did not hear an improvement I hope you were able to send it back for a refund.

I have done a lot of tube rolling and enjoy that part of the hobby. In the 6SL7Gt family, I am sure I have over 10 types. Of those the 1959 Hamburg Germany, Valvo, and the Italian Fivre do something special in the Zana Deux amp. The Tung Sols, National Unions, RCAs, Sylvanias,Brimars, Mullards, CBS, Hyltrons, etc.not as much change. Unlike the Red and Black fuses discussed in this thread, none came with a 30 day trial.

It is interesting that not many people seems to think that tube rolling is a fool's errand . I think rolling tubes , fuses and A/C wall outlets all change the sound in my systems.

I also think Power cords can change the sound of a system especially once one begins evaluating products not of the entry level category.

I find it interesting and sometimes money and time saving to read what others have tried. Especially those who make changes in a systematic way and then have the talent to articulate the sonic changes they experience. None of us have the time to try all the tubes, fuses , or power cords out there.

Because of this thread I have tried the Black fuses and they have improved the sound of my systems. So I reported my results.

At Head-Fi.com I read about 6SL7GT tubes used in the Zana Deux amp. I tried a lot of the tubes and reported what I heard.

I hope you will list the components that did not respond to the SR RED fuse. It is possible you will save other owner's of the same equipment some time and money.


I do not understand when some people experience a different result than others, they feel compelled to cast negativity towards those persons.

Thank you for listing your components that responded to the SR Black fuse. I do think publishing specific component results will be helpful to future readers of this thread.

I find it very interesting that so many of us are getting astounding results from the SR fuses ... and yet, there are the few who get nothing out of them at all. I understand the skepticism though. Early on in this thread I made the statement that I've been burned before by tweaks that didn't work ... and if it hadn't been for the 30 day return policy, I wouldn't have tried the first SR Red fuse that I bought.  I'm so glad I did. I can't think of any other tweak I've tried in over 40 years in the hobby that has made such an outstanding improvement in the system. I've made similar improvements but its always involved major upgrades in equipment. A case in point was when I replaced my ARC SP-14 with the ARC REF-3. Or the ARC Classic 60 replaced with the REF-75. Those were major improvements, but not more so than upgrading to the SR fuses and power cords.  Why there are those who cannot hear the improvements is beyond me. A mystery to be sure.

Did you get the Kapsberger/Dowling lute CD yet??

After all every piece of equipment that everyone owns, is made using the laws of electronics and test gear to develop it. Anyone who has something that’s not made using these has voodoo gear."

George, we’ve already gone over all of that. There is nothing voodoo about the Mpingo discs. Ignorance of the laws of science is no excuse. The particular method of operation is actually provided on the Shun Mook web page for Mpingo discs. Don’t get so freaked out by such simple and easy to understand audio devices as Mpingo discs, tiny little bowl resonators, Shakti Halographs, Marigo VTS dots, Graphene fuses, or what have you.
