Synergistic Red Fuse ...

Can changing fuses have an effect on warranties?  Sorry if this was mentioned already. Thread's kinda long to search.

Always check with manufacturer! My equipment is not under warranty so I do not worry about that possible issue . Having said that, If I screw up my equipment- I am the one to pay the bill. I believe that the Synergistic Research fuses are safer than the 10 cent fuses. My systems now have a total of 22 SR-Black fuses.

OMG!

The SR black fuses (2) just went in the kit cold from the post box, about 30 minutes warm up, and I que up the first record, Susanne Vega Close-up vol.1. Between the fingering of the guitar, the bass line, and her breathy voice all are more vivid (than with the stock rat shack fuses), no question.

She may present a bit raspy and not quite as ethereal, or liquid, the performance at times may sound a tad confused, which should resolve over time. Now I haven't tried flipping the fuse orientation yet though, so we'll see about that. I look forward to these, very much, after adequate burn-in time.

Fortunately my preamp and phonostage are hybrids and though the signal path is tube driven, the power supplies are SS and basically never get turned off, so the fuses will see current without a need to run the tubes (or my ears) for their entire break-in period.

Does this sound about right on first blush gentlemen?

^^^ Yep, just about right r_f_sayles ...

The Black fuses reveal their promise right from the initial installation. You are most likely noticing a hard edge to peaks, strings and higher pitched instruments like flutes. In addition, the music just doesn't seem that involving at first either. As they burned in in my system, the fuses just seemed to open up from one listening session to another. At that point all settles in and the improvement from just a fuse swap is quite an ear opening. 

Please post your results as your two fuses break in. Thanks ...

Slippery slope......

I can't believe what I have just done. I just became one of the first owners of the black cords. Ordered 2.  One for CD player and one for preamp.  With the free fuse offer, I ordered two for my scd-5400es. One for the digital transformer and one for the analogue transformer. They will replace the furutechs that currently reside in there. As well, a black fuse will be replacing the red fuse in the preamp. 

I am a bad man.
