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? 

WRT atmasphere's statement, "I have exactly that in mind."....I might be very interested in such a creation. I hope I'm paying attention when it's announced - hopefully in 2018(?).

I'd agree with that. There's plenty of amps with extremely good specs that sound as clinical as a prostate exam. My F5 clone will do .005% distortion, but it sounds better with a dominant second harmonic at about 10 times that level. 

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? 

Yes in "some" cases they are engineering the musicality right out of them because too many audiophiles are demanding more detail from their gear. Excluding Class D amps how much more positive advancements are left to improve upon both in preamp and amp designs? I know there are different topologies applied to some designs and when you purchase a certain  piece you are agreeing with the designer on what he thinks sounds good.

Just maybe twenty years from now people will searching to buy the gear you own right now because what they are currently dealing with sounds like crap.
