The basic article is rather rife with false assumptions and simply wrong information.
Much of the article seems about power (the amplifier)... and I've got gear at my house spanning the past 30 years.
Though he discusses power; let's start with the actual sound quality... a well built amp will work with no discernable loss of soundquality. Period. Decades of testing by basically everyone (not to mention a simple oscilliscope) show that a properly built amp, driven within its limits, has no audiable diviation from "perfect".
It was true 30 years ago. It's true now. If there's "a sound" to your amp either
1) It's deliberate.
2) The amp is junk
3) There's a problem.
So what about power? Well, McIntosh (my 35-year old is 120Wx2) makes amps up to 2,000W right now; and there are others that go higher. Peavy has a class-H amp at best-buy that's 1200W @ 2ohm for a couple of hundred dollars.
But any discussion of power is just stupid without a discussion of load. As we've moved to self-powered subs and smaller mains: the needed power to drive speakers has gone down. Sure you can get a set of B&W800s or such... and for you the high-end store still carries huge amps.
There's so much that can be said but the short of it is, unless you actually screwed up, it is the speakers, not the amp, that determines the sound.
