NEW PROTOTYPE FUSES COMING >>>

I would guess maybe Hifidelity audio cables ,will be making fuses 
I feel that is a solid guess,since their 1260 nano fluid is doing well. .

Oregonpapa   How many hours did they tell you was needed for fuse burnin ?
synergistic says 250-300 hours  for their fuses.

One person advocating fuses here has > 30% of their system budget tied up in cables. I can’t take this persons views on anything seriously knowing that.

+1 and some!!

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)

@ audioman58 +1, 

I think for the QSA fuses it's 75 hours. It's remarkable the sound quality you get from QSA fuses WITHOUT the full break-in period.

Frank - I have 4 yellows in my system that replaced SR orange.  I am trying to hear what you hear.  Can you please explain Midrange.  Sorry for such a simple question but it will help in my listening efforts.
