I think I've condensed in only 4 Laws the guideline for the best-in-class audio chain

And even if you wanted to, there is no solid evidence that that is true. There has been a lot of puesdo-science applied to this question, it should all be tossed out.

The opposite could also be said to be true, where does that leave us? There is too much talk in absolutes here. I would suggest, in fact I think I already did, that amplifiers can be made accurate enough that they can effectively be forgotten about when it comes to having a meaningful effect on the sound other than one of a glorified tone control if that is your subjective preference.
 
While misattributed to Alan Greenspan, and no matter how pareses, it’s never been more relevant:
“I know you think you understand what you thought I said, but I’m not sure you realize that what you heard what not what I meant.”

And Paul Simon: “ a man hears what he wants to hear and disregards the rest”

As for the specific point of “transparency /accuracy” of electronics - more specifically power amps- my experience with several builds last year of SS kits of different topologies and power levels was very enlightening. I’m currently quite enjoying my Mod286 amp - far more so than the putatively higher powered Hypex UCD, or the NP ACA Class A. The DIY Audio kit of the latter design is a quite well packaged and very easy build, but the 286 just gets out of the way, and while great for HT subs, the Hypex has a very hard and glassy top end to my ears - particularly when paired with Alpair metal coned A10.3, Pluvia 7 or A6.

The Paul Simon quote will forever be a concise truism, as for the other quote, it's just a form of snobbery because it makes too many pompous assumptions.

Amplifiers can make a big difference in the performance of a hifi — i have heard many of them. Many are good, many are not (more). And few are really great.
Of course, that's because they are designed to sound different, for different tastes/markets, it's subjective.
 
Damn iOS spellcheck- that should have been “parsed”. One of my foibles is self delusion as to being succinct and not contradictory, another the possession of a modicum of self-awareness.

Matt, as to your last point, that assumes that the designers consciously build such subjective “tone control” into their products. While I’m sure many do - Nelson, I think makes no bones about that - but I’m not sure it’s a truism.

If 2 amps sound different and yet are both called accurate would be an illustration of how far we still have to go with amplifier design. dave
That is impossible. Either it is accurate or not. If to amps sound different, it can be that 1 is accurate or that both are not accurate. But both accurate is impossible in this case. If 2 amps sound the same, they can both be accurate or both not be accurate. This is elementary school logic, not that hard to understand. Edit: Accurate means here no audible difference between input and output.

Either it is accurate or not.

Exactly.

Either that or that amps have far enuff yet to go in development towards accuracy and it is still possible to have 2 amps that are equally accurate but sound different — a situation that certainly exists with speakers.

Or we still don’t know what accurate means.
