Hi-Fi Tunig Fuses & Parasound A21


Hi,
Have any Parasound A21 owners replaced the stock fuses with the Hi-Fi Tuning fuses in their amp? I understand that there are four 8A slow blow internal fuses and one 12A slow blow fuse on the rear panel. This is a awesome amp as-is. Just my curiosity.

Please share your experiences.

-Thanks,

An example of a fuse in the signal path I think everyone can understand is a fuse in a speaker. Case closed.
Auxinput, thanks for the explanation. After reading all the posts on how a fuse can or cannot interact and affect the signal path, your's has what seems to be the least amount of spin. 

It could very well be that due to my bias it sunk in but I've been temporarily swayed by arguments that go against what I actually hear only to come back to believing what I actually hear. :-)

All the best,

@auxinput- I ended up ordering Hifi Tuning Silverstar (the main fuse) and Classic Gold (rail fuses) which are on their way. I would first try the main fuse to see if this improves the sound at all. If yes then I would replace the rail fuses. I would post all result hopefully by the end of next week.
I wanted to find if folks here have an idea of how much changing the rail fuse would contribute to the overall improvement in sound under the assumption that changing fuse improves sound quality. Any feedback would be greatly appreciated.
Also did anybody compare performance across Hifi Tuning (Classic Gold, Silverstar, Supreme) and Synergistic Research Quantum Black fuses?

Thanks.

Still, no proponents of the Magic Fuses and their ability to make cellos sound better have EVER offered up any reasonable explanation for this…good, simple Littlefuses that cost maybe 6 bucks do the job just fine (failing if need be…that’s the job), and the entire premium fuse market is simply the "lets get a tiny item cheaply made in China for big bucks…small and easy to ship, make up a technology and provide the myths, and sell ’em to the unwary." Excellent business plan…and it works! If you think you and your system are sensitive enough to allow you to hear what premium magic fuses supposedly do, you may actually need these things to validate yourself. Otherwise, do what actual music and sound professionals and amp designers do…ignore the nonsense of silly and fraudulently marketed psuedo tweaks.

That’s simply not true. Repeating that line a hundred times actually doesn’t make it any less false. There are none SO blind as those that will not SEE.
