I would read Nelson Pass's writings on the evolution from the X to X.5 to X.8 series of Pass amps, as well as the same for the XA series...
darTZeel NHB-458 monoblocks.

no negative feedback. only 6 active devices in the signal path. astonishingly low noise floor. 500 watts into 8 ohms. all the circuits are suspended inside the chassis for excellent built in isolation from feedback.

amazing first watt; yet very powerful and authoritative.

the best of tubes and best of solid state. sounds like music.

you can have it all. but....there is always a but.....it will cost you.
THose Datzeels are very interesting. Should be for $150000.

For most people in this world, I'd say advancements in Class D amplifiers is the thing that most people with modest budgets should be looking into. Class D is a different ballgame altogether and the most recent models and technology delivers in spades IMHO and many others as well.
They do a better job of rounding the heat sinks off now so you don't cut your hands when you go to move it.
