Why don't amplifier Companies use high end fuses?

I just think the company
Has to bump up there price if they put a $100 fuse in.    I have tryed the
Black fuse.   The 30 day  trial plan.  LOL. 
you won't want to  get
The damn things out.   if you get a great deal buy them.  Only make sure its a great deal.  I would rather buy a $100  5th. Of
Tequila.  I've hear more 
With a change for the better in a nice wall socket

At least you tried to spell my nick right. I’m nowhere near saying all cables or amps sound the same. I’m once again balancing the distortion character on the F5 I built and I know that thing sounds different than other amps. It’ll sound different today than it did yesterday when I’m done with it. Cables? Yep, those sound different too, in an extremely nuanced way. Just like building the amp, I built cables to see what differences I could notice. I actually surprised myself there. I A/B’d both channels to make sure I was hearing what I was hearing. There was a noticable difference, but hardly a "completely unlistenable" difference like Auxinput claims a tiny little fuse in the power supply makes. I’m more than happy to try different things out. I’ll probably drop a dual mono power supply in the F5 at some point to hear the difference. I’ll probably build other amps and pre-amps. I’d like to build better cables. Fuses? Sorry. Auxinput is just lying when he says it made a 3dB difference. There’s no physical phenomenon in the universe that would explain that and that’s a difference easily measured. If the differences were that obvious that would be a big issue. There are so many other things to be tweaked and manipulated before worrying about something like a fuse. Things you can actually measure. I’m reading the posts here of people that couldn’t even tell me how well their active devices are paired, or how they’re being manipulated by degeneration or feedback, or how high they’re biased, but they’re fretting over a fuse. The signal path resistors make much bigger differences. Where’s all the threads debating those? Fuses are the playground for those who lack the understanding of what’s inside the box.

We're talking about trying a $25 fuse in a $7000 amp. I don't think anyone's worrying about it...

Well, to be fair, I'm not sure I would characterize most of the naysayers' comments as intellectually sincere or even honest. Nothing like that. They just enjoy giving audiophiles a hard time. Nothing so lofty as any kind of intellectual argument, nothing like that.

Kosst, for the record note that Auxinput did not say that. It was another member who said that "I had to turn down my volume by 2-3db because after changing directions, it was too loud."

Also, IMO both Auxinput and the member who made that statement have over the years established excellent reputations for sincerity. That said, however, I agree that the stated 2-3 db effect is simply impossible, and was probably due to either some other variable or to misperception.
