Voicing an amplifier: general discussion

As I said (why do I need to REPEAT this?) :in a sound system chain insert a few competent amplifiers (behind a curtain , don't cheat 😉 ), switch them in at random and try to pick which soundstage is which
By ear, of course 😉
I have done EXACTLY this, many times. Sometimes the differences are too small to notice or give credit. Other times they've been so huge as to be shocking, leading to much laughing and head scratching.

But feel free to ignore me, I'm just some guy. I'm not even published in the subject.

Yep , sometimes the difference shows up over time and not in a quick switch back and forth ...
 
Hearing audio differences is my 'reality', not my opinion. Yes, I indirectly make my living designing audio equipment, so I 'could' be biased for audio differences, but I am also far more experienced in audio design and its trade-offs than almost anyone contributing here, and this helps me be MORE OBJECTIVE than most here.
The way to escape from the 'madness' of listening to equipment, is to listen to recordings, 😛. This is what I do ... I put on an album and listen to the music, and only the music - and this is either reproduced at a satisfying level or it isn't. If the latter - something is 'wrong' or irritating or disturbing in the sound - then my playback system is faulty, or not working to a high enough standard. As simple as that. I have been tempted, at times of weakness, to think, no, this recording is just too impossible to make come good, there are too many problems with it - but it has always turned out, always, that it was a moment of weakness on my part to think this way - a good breath of fresh air, a bit of inspired thinking, and the energy to re-apply myself to sorting out aspects of the system, persistence - and then out pops sufficiently good playback to make that recording come to life ...
 
It would be handy knowing how to make an amplifier sound good. I've made audio circuits sound good before, but at this point, after over 20 years, I'm not entirely sure how.

...

It's been historically fun to make "I know, right?" jokes in the midst of something spooky, but that's getting to be a useless, ancient human trait at this point. It's time to advance.
Thanks for that post, Andrew. Your journey mirrors my own in many ways, it's a hard slog at times trying to understand "what's going on??" - but the good news is that persistence is rewarded; slowly, bit by bit, greater understanding evolves - I have never gone backwards in this quest ... yes, great frustration at times, but then down the track new insights and renewed energy get one back on track again ...
 
I'm amazingly lazy, that's probably the reason.
And on the other side, they don't want to know that there is anything more to it, it would spoil their cosy comfort zone of beliefs built up over the years - subconsciously, they would probably "wreck" any serious experiment to look at this, because they carry too much emotional baggage, invested in one side of the "argument" ...

the same can be said about you....😉

That's a common misconception about abx and double blind testing : you don't have to quickly switch back and forth, you can listen to the equipments being tested as long as you like.

When you, the person being tested, asks the equipment being tested to be switched , the switch between equipments should be very quick, so as to not waste your hearing memory.

That's probably in respect to the DBT and "no peeking" issue - the thing is, I realise what the traps are in this, the numerous flaws in the procedures - so if I did such it would be on my terms; for example, choice of source material, volume levels listened at - I know precisely how to stress test the systems, conventional clipping being nowhere in sight - to make it ridiculously obvious where the differences are.

My belief change happened in an instance, it did not take years to evolve - one day I was listening to conventional audio sound, the next I experienced a good slab of the "good stuff", that experience is locked in as solidly as learning how to ride a bike - people gabbling on about scientific studies "proving" that it can't happen ... I just shake my head ...

You, sir, are projecting.

The more technical people in this discussion don't believe in amplifiers having prat, a sound stage of its own etc because they have never been exposed to any evidence to its existence, not because of a closed mind.

Au contrarie, given any evidence of the existence of these effects I really doubt anyone here would say they didn't occur.

The fact, however, is that there isn't a shed of evidence for their existence and all serious testing ever made have failed to come with any evidence at all.

Hearing memory is not an issue when focused , by time i mean days possibly weeks. Many amplifiers flatter to later decieve. Once the offensive demon is reconized then its audible regardless of switching or not . also decision made on sonics is never done on one listen or in one system , consistency is important ...

I have found going back best after auditioning as oppose to going forward
