My ears are ready to retire!

Here is your system.

Streaming.
Nad pre...(I use a 7130 Receiver).
Carver m200t amp
Suca tube pre amp as buffer between pre and amp..(45.00 on Amazon)
Arcam Rblink Btooth DAC.
Important! Use an Ipad Mini for Music Playing.
PSB 300 or 300i Bookshelf Speakers.
Play them into room. Sound 10 times their size.

I'd also recommend the Naim.. Uniti Nova.. and good speakers, all you'll need. 

Keep it simpler .....

Sub carver for Nad 7020 receiver. 
Still use suca tube pre buffer..

NAID M10 Streaming Amplifier would be perfect for someone after digital and all in one good quality and pairs with all kinds of apps (ios/android/mac etc) so you can stream from Tidal and Qobuz.  You can decide what speakers to use but should be relatively easy to match with your new downsized lifestyle.
