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

inna,

" music can't even be recorded as performed let alone reproduced"

It turns out this is not true. You have formed an opinion about the current and past recordings based on what? An admittedly poor reproduction system? If you take the distortion out of the playback electronics you would be shocked at how much captured detail and imaging data is embedded in the recording including cues that trigger the sensation that it is live.

I mean it cannot be fully recorded, I did not say that it cannot be recorded well except big orchestra opera and big choral pieces - this is especially tough.
In any case, I believe that amps and wires without gain are already quite good, that is not a major problem. Turntable set-ups and open reel decks are quite good too. Problems are the recordings themselves and speakers. The beginning and the end, the middle is acceptable even if it may cost a fortune to be that.

Now days it seems anything gets copied or is a copy of something else.
