When I have seen people listing their systems lately

16/44.1 is not literally perfect. It may be good enough (or even overkill) for the intended purpose (human listeners), but it's still an approximation of the signal. No analog or digital reproduction can claim to be "literally perfect".

Had you not included the "literally". I'd probably have skipped this reply, because your point is taken

I have a PS audio DS, and I have been with computer based audio since 2004.
Guess what I noticed that the music coming out of my Sony 5400es satisfy me the most. I buy used CDs regularly in Amazon even when I can listening on tidal. Tidal is convenient and the best quality streaming source but I still prefer the CD quality. Nothing is written on stone yet related to format it is all very subjective, connected to convenience and the music you own.
I am not planning to sell my Sony anytime soon. Yes I use foobar with windows flac files, audirvana, iTunes with AIFF, and vinyl on my VPI.
My 2 cents.

CD/SACD players are not dead!

I log many hours each week listening to tracks on my music server. 90% of my listening time.  I rip all new CDs to server up front. Have not played a cd since about 2009.   CDs are fine but listening off a music server with good streaming software takes things to a whole new level.  No going back once there.  

grounded on the sandbar of reality..

Imagine IF your fave artist just worked on what you needed...
