Why don't amplifier Companies use high end fuses?

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.

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.

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.

Lots of things in this hobby are "impossible." Lots of things in this hobby defy explanation. Lots of things in this hobby appear to disobey the laws of physics. So what else is new? 😛
Just wait’ll you guys get a load of some stuff that’s really controversial. Tempers will flare.😡

Thanks for the compliment. Yes, it was me who said that I had to turn the volume down 2-3db and it was not a misperception. My normal listening level is -37db. That was with both the HIFi Tuning Fuses and the PADIS fuses in, the wrong way.

Both times that I reversed them, I had to turn it down to -39db to -40db  as it was just too forceful, i.e., too loud. The only difference between the two fuses were that with the HiFi fuses, the highs were too rolled off and I had to boost the treble 2-3db just to hear things in a somewhat proper perspective. That was rectified once I reversed them. All settings returned to a flat, direct setting. 

With the PADS fuses, that was not the case. It was the same with the volume, however. I now listen at -39 to -40db all the time while for the two years before that, it was at least set to -37db. That's the god to honest truth. As to what other variable it can be attributed to, I haven't the foggiest. What I did and what I heard as a result, with my eyes, my hands, and my ears, is that not only do the fuses improve the sound, they are directional. 

I'm not inclined to pop open the units and get out my Rat Shack meter to measure the SPLs with test tones or quick and slow readings, going back and forth with the fuses. Been there, done that, twice already, just trying out the fuses. It never occurred to me to document the process as I never expected some of these responses. Someone else can do it. I know what I've heard. I'm not delusional. I try to respect those who disagree as long as they're open minded (like you, Al 😀) and I hope this lays things to rest, because as far as I'm concerned, I'm done with this.

All the best,
