Synergistic Red Fuse ...

Well, I've put these SR Blacks in all my home stereo setup and am fully impressed with what they have done with the sound of my system. Worth every penny for the improvement they brought.

I have a little desktop system at my work with Nappa Acoustics speakers and recently picked up their matching hybrid integrated amp for $400. Of course I just had to replace the fuse after the performance I got at home. It took a little longer than the typical 70 hrs but that little black fuse really turned that Nappa Acoustic amp into a stunner! 

These Black fuses have increased the performance of my system more than any tube or cable could ever do. Thanks Oregonpapa for starting this thread!

Charles1dad glad you liked it and I'm also a Cyrus Chestnut fan! I would check Steve Nelson out thanks for the tip!

T_ramey,
Congratulations,  the list of happy Black fuse users continues to expand. Frank, see what you started ☺
Charles, 

Wow. What rhetoric. 
I have invested in reference level audio equipment and am aware the fuses therein,as in other electrical products,are there to "protect the equipment". The parameters of that protection are well known to the designers. The designers of products at the level of Spectral Audio (a fairly well respected brand) are definitely looking to maximize sound quality-that is the basis of our high quality (high end) equipment, and they seem to take extreme engineering design,innovation and ever improving parts quality to the utmost levels to produce competitive gear. So,can we not assume they would want to supply a power cord, and fuses, that would best show off their products --i.e. "allow" them to operate at their maximum level?
In younger days I would have 'logically' thought so. However, the utterly basic power cords supplied with some of the very best reviewed equipment are certainly not worthy of the task. My experimentation (and now ownership) with all of the top of the line MIT Oracle p/c's has clearly proved to me my 'logic' was incorrect. It has proven continuously, with analogue and digital equipment, that "stock" power cords are inappropriate on serious equipment. I have not experimented with fuses,so far, as the cost of failure of any fuse has been an unacceptable risk. I am now retired and don't have the funds to replace the reference level equipment that provides me such enjoyment. I have found vast improvements in experimenting with ac power supply isolation and conditioning and would very much like to further optimize the sound I obtain. However, when I compare the websites of the vaunted "hi-fi fuses" herein, with the website for example of "LITTELFUSE"; I am more impressed with the engineering,research,quality control,pride of performance-and willingness to stand behind their products with very detailed data shown by LITTELFUSE.   How do I determine the "hi-fi marketed" fuses will perform similarly?  Most sincerely,long time member and avid enthusiast of musical reproduction, Peter.

Peter,I can understand your concern. But rhetoric is what this hobby is based on. The next best, greatest, and cant live without tweak is always just around the corner. I can remember when power cord nay-sayers would have a connipshit about the evil rhetoric in concern of power cord/conditioner benefits. I believe that has been put to rest.

I use an SR black in my tube pre and I can say in all honesty that most of the rhetoric here is true. I say most,not all,because some posts are over the top in wishful thinking from my viewpoint. Its a fantastic tweak that does have worth in a revealing system. Of course ymmv. Give one a shot and see what all the hoopla is about...
