A few months ago I purchased a used pair of speakers from another Agon member.
To my surprise all the fuses were Orange fuses. I listened to them and then to satisfy my curiosity I replaced them with ordinary buss fuses and could not hear a difference.
I did this test with a bunch of friends and neither I or them could hear a difference. Kind of just says it all doesn't it?


To those non technical thinking of purchasing these $$$ fuses. Just save your $150+ and do this instead.

A fuse:
1: two end caps
2: short piece of fuse wire connecting the two end caps through a glass tube (that’s all she wrote).

To those "non technical" members that are interested in "maybe" wasting their money, do not listen to the non-technical, listen to the technicians of this industry that design the audio products you have and listen to. AND YOU WON"T SEE THEM ON THREADS LIKE THIS AGREEING WITH WHAT SAID HERE ABOUT THE SOUND IMPROVMENT DETAILS AND AC FUSE PLACEMENT DIRECTION, EVER!!!
Just clean and tighten your fuse holder and re-new your fuse (if old) with a good quality 50cent Bussman, Littlefuse or similar.As with "many switch-on surges" they do deteriorate, bend, stretch and get crusty with electrolysis formations on their fusible wire elements before they give out, as these pics show of a fuse wire element ageing over time show. https://ibb.co/9NbTwqK (even the $$$ boutique ones will age just as much also)

Just upgraded from 2 Blues to 2 Yellows in the phono and poweramp. My premap already had a yellow fuse in there.

With just under 12 hrs on burn time, the system is sounding pretty crap. Quite bright/Thin and the music sounds quite constrained. Doesnt have any body to the sound. And yes the fuses are installed in the correct direction.

Also with the new Yellows soundstage is very small and the music plane is very flat with little depth

When i initially got the Blues in my system it was an instant no brainer with instant improvements all round. This was coming from factory fuses. The Blues then continue to improve over a 4 week period.

I hope the yellows will improve over the next few days.
