Synergistic Red Fuse ...

I have about four or five hours on a Synergistic Research "RED" fuse in my amp. Very worthwhile improvement a great value.
Don't judge it right away the break-in is kinda odd in my case after about twenty minutes things improved dramatically. In a couple of weeks I may swap it end to end see if that changes for the better. I'm inclined to just leave it alone it sounds so good as it it.
Thank you for suggesting this and all the comments too. Who would have thought a silly little fuse could affect things like that.
Will soon order another for the CDP.

Since SR RED doesn't offer exact size for my REF250, I've been using Isoclean.  It well exceeded my expectations but the audiophile in me had to order RED to compare.   

Well after 6 hours, they sound very similar.   Probably RED is a bit more open and airy.

I have used both Brands: Isoclean and Synergistic Red. I will be interested to hear your comments after 25 hours on the RED. For me they both improved the sound initally but with further break in- the RED continued to improve to a greater degree. Also after some break in time it is worth the effort to reverse the fuse direction to see if there is further improvement.

I'll stray  away from the primary topic for a moment. Lak burned in my Afterburner 8 AC receptacle on his Audio Harma cooker for 160 hours and I sincerely appreciate his kind favor. For 79 dollars this is a very worthy product and on par with the SR Red fuses in terms of genuine sonic impact. I can easily compare it to  my standard outlet in the same wall,. The Afterburner 8  is clearly an improvement, jaw dropping?  No, but unquestionably superior sound quality. 

As with the SR Red fuses it doesn't change the innate system character but it does improve the clarity, openess and there's more ambience retrieval and nuance. The generic outlet is by  comparison marred by a thin layer of haze  and hash. This isn't apparent until you use the Afterburner 8 receptacle, then it is obvious. I use the Tripoint Troy which is a passive grounding device that plugs into a wall receptacle for grounding purposes. The Troy is clearly  better sounding  when plugged into the Afterburner 8.

The main  effect with the SR Red fuses  and the Afterburner is increased purity of the sound. This further  improves the musical engagement,  naturalness and realism,  which is my objective, the  presentation is very organic, tonality and timbre are superb. If you're very happy with your system and have no desire to change the components, these two products will help you get the most out of your present system. 
The ROI is exceptionally high without question. Two  products for less than 100 dollars each that truly make a very  noticeable improvement. The next step is to put the SR Red fuse in the DAC.

Would you provide a link to the seller of the "Afterburner?"  

Thanks ...
