We Need A Separate Forum for Fuses

I also built tube gear and the fuse is a bottleneck even in the most robust power supply. Best to avoid altogether and use a nice on/off breaker.  Next best is a nice aftermarket fuse as they do indeed improve SQ.  

Imo one of the most foolish notions in HiFi is the idea that the better the design, the less sensitive it is to changes. That's called mediocrity in my book, and if any piece of gear operated on that principle, I would consider it junk. 

Yes....fuses should have a separate forum but that forum should be on it's own server that is capable of handling numerous emails and responses. Let me agree with the few that have said that "no fuse is the best fuse". But, a fuse is protection. A fuse is like a cable. It can't add, only take away.
I've been in this "hobby" for over 40 years. Like a "gear head" with cars, audio enthusiasts strive to improve their product no matter how mediocre or outstanding it is. No harm in trying simple tweaks and sometimes they work out well. Fuses are subject to alternating current as are power cords and the like. Sorry...I'd need scientific proof.
Case in point.....we've all heard about "burn in". Sure, some components benefit from some sort of continual use. But what it really is for the listener to burn into their brain that "hey...this sounds better". OK....flood me with your digs.
A friend has over $500K invested in his system. Sure it sounds great. But, he admits that the most improvement he made is with sound treatments he made in his listening room.
So, buy those fuses and if you think they make better sound... GREAT. I'd put my money elsewhere.
 

No digs needed @jrpnde. Glad to have you aboard. It wasn't until just half way through your post that I thought you were leaning towards accepting aftermarket fuses, but there's still time.  😄

Sure, it can have burn in, like a cable and other components that benefit from it and yes, it's purpose is for protection, but like you said, if it sounds better without it, why couldn't a fuse that's made to a higher standard than the cheaply made one sound better? It would most certainly conduct better and vibrate less, which would impart an improvement. 

All the best,
