Are future improvements in Amp/PreAmps slowing to a crawl?

Look at the specs on a Benchmark ABH2! Can anyone find an amp with better performance specs?

It could be said that this amp is chasing a few specific specs and is using a lot of feedback to get there. So it may sound squeaky clean, but does it make beautiful music? 

Not going to reveal too much, but we solved one of the major sources of distortion in class D amps. And we have proof of concept.

Will this fix the weird decay issues that Class D amps can have? Where sounds decay too quickly and leave dead gaps in the music?

Musicality is a meaningless term that can’t be measured. Improvements like SNR, channel separation, THD+N, and power into various loads are measurable.

I find SNR & THD+N to also be meaningless. Same with THX certification. However, I agree that the best switch mode power supplies are really good these days.

Benchmark is a very good company. They take pro gear and package it for hifi buyers. If your flavor leans towards the clinical side, they could be an excellent fit. They won't embarrass anybody that shouldn't already be embarrassed. Only Schiit can do that. ;-)

If you find outstanding (better than anything else on the market or ever mass produced) measured performance to be a meaningless achievement then how do you propose to measure what you find important?

My ears and brain work together and outside of their limitations, I don't care because it's beyond my hearing and comprehension.
