HiFi tuning fuses, some benefits help

I found them to work well in some situations. I had them in an audio aero Capitole SE cd player. It made a nice improvement to the presentation. More natural details and slightly lower back ground noise and a richer midband.

I have them in my DCS cd player and they made a very small but noticeable difference mainly to the high frequencies. Great in ARC pre amps.

Worth a go.

My Mains are modded Cary tubed monoblocks, and the improvements I mentioned were most noticeable in that app. I've also installed them in my modded TransNova 9505 woofer amp, but installed IXYS soft recovery FREDs at the same time, so I can't honestly quantify their impact or contribution to the speed and definition I gained there.

Jwong - Thanks for your reply. My response, probably a bit of an over-reaction, was not directed at your comments specifically. I have to say I was a bit surprised they made a difference in my system but that also applies to changing out interconnects, power cords and speaker cables. I was a real skeptic about a lot of this stuff before I tried it but now I'm in the camp of "it all seems to make a difference". The bottom line is go with whatever helps facilitate access to the music. Take care.

Way back when, Peter Aczel from the Audio Critic(before the 10 great audio lies)in about 1980,he suggested that speakers which has fuses, actually sounded better if you bypassed them altogether.
So chalk one up for those who feel fuses do have an influence on sound.
I stuck with this mindset and replaced the speaker protection fuses in some of my amps also.
In every case the sound opened up, nothing blew up or burnt and I am still here 25 years later.
When the IsoClean fuses came out I gave them a try, and yes they were better than the cheap stock fuses but still not as invisable as the solid chumks of wire I had been using.
At under $30.00 a fuse, they are a cheap upgrade and give you peace of mind, which is a nice compromise.
The need to use fuses in any design is a sonic compromise that in this modern era something I believe we can do without.
We should banish them to only the most rudementary designs.

Keep in mind, though, that fuses in speakers, and speaker protection fuses in amps, are directly in the signal path, while ac line fuses are not. Also, the current that is conducted through speaker and power amplifier fuses is both large and fluctuating, while the currents that are conducted through the ac line fuses of line level and source components are small and relatively constant. Different situations altogether.
