Synergistic Research Black fuese

Who has tried the new Synergistic Research Black fuses?  How do they compare to the Reds?  If you are using the Blacks, do they live up to the hype? Thanks
There is an entire RED fuse thread in the "Amps & Preamp" section that has evolved into the BLACK fuses. I think at this point its seven pages long. Its all there for you. 
I never tried the SR Red fuses but still had their Quantum fuses in most of my equipment. I just got some of their Black fuses and will say they are exceptional and clearly better than the Quantums. They only have about thirty hours on them and SR says it may take far longer than this but they are a very nice addition to my system that already staggered my realization of what was possible.

You are absolutely correct. The Synergistic Research Black fuses really start to sound good at the 25 hour mark. But then the sound continues to expand and relax so that at the 100 to 150 hour mark you are really enjoying a higher level of emotional envolvement  with the music.

I hope to see you at the Newport Beach show June 3-5.

I've been rolling fuses forever so replaced all 7 SR Reds with SR Blacks in one shot.  The most obvious change is a more musical and organic sound where SR Reds sounds hifi-ish in comparison. 

Everything is system dependent but SR offers a 30 days money back so no risk trying in your components.

Sounds like you rolled a Seven and came up a big winner !
I absolutely agree the Synergistic Research Black fuse can really improve a system. For me DACs, amps, SACD players, self powered sub woofers, and even a self powered sound bar have all had an improvement in  sound with a Black fuse installed.

davidpritchard, yep lucky seven :-)    Got an 8th for a SS amp rotating in for the summer soon so hoping lucky 8.

Audiophile fuses are a no brainer if your system is worth one's salt.  But if it's a pig, applying lipstick, it's still a pig so please use common sense.  If a fuse doesn't transform your $399 amp to a Pass XS300, it's expected!
These SR Black fuses have brought my system to a place far beyond where I would ever have imagined it would be. The system was no slouch before the fuse experimentation ... but now its in a completely different sphere altogether.  Vocalists and instrumentalist are in the room ... with good recordings, of course. I have tons of mono LP's and they have really come to life. Mono on the system has friends saying ... "My God, who needs stereo?"  I wish I could  have some of you over to hear Paul Desmond's alto sax on some of my mono Bruebeck albums. Wow!


Boy did Paul Desmond have a great sound that the Synergistic Research Black fuse really brings to life. It is like you can look and hear all the way back to the vibrating reed in his sax.

It certainly is a great time to be an audiophile if one is willing to audition the various components and create a truly synergistic system.

I agree with others that the SR Blacks are remarkable.  That said, has anyone had problems with the Black fuse blowing upon preamp or amplifier turn on?  This has happened to me a couple of times and I am currently working with Alfred at High End Electronics to figure out what is causing this situation. The SR Black fuse ratings are the same as the OEM fuses that I replaced.  

This has happened with a Synergistic Research SR-20 fuse in my headphone tube amp (Eddy Current Zana Deux amp. The amplifier manufacturer had me go to the next largest fuse and since then no problems.

The SR Black fuse really does improve the sound.

Thank you for your quick response. I agree that the SR Black fuses do indeed make a significant improvement in overall sound quality. It is also interesting that you mentioned going to the next largest fuse... I suspect that is what I would try next. Best regards, Al
I did go to the next largest fuse and that did solved the problem! So thank you for the suggestion.  Alfred at High End Electronics was great to work with and supplied replacement fuses in exchange for the blown fuses.  He did share with me that the SR Blacks tend to be on the sensitive side.  The sound quality is a big step up from top to bottom.  It is just amazing....

I am glad you are enjoying the sonic improvement with the Synergistic Research Black fuse. Alfred Kainz is a real gentleman.

If you are still using an ordinary wall outlet, I hope you will consider one of the many good Audio quality outlets available. Fuses and outlets are two areas that really respond to upgrades.

I'm thinking about trying these in my monos but reading there were a couple of occasions of them blowing is slightly disconcerting...the manufacturer state to use sand filled T6.3A so would it be a straight swap or a different rating considering the sensitivity of the Black...??
I moved up to the 8A and had no further problems with the fuse blowing. Highly recommended due to the improved sound quality which iis a significant step up!
