@wsrrsw thanks for pontificating! And I too love the artwork.
Probably 75% or more of my listening is jazz, bass jazz, sax jazz, contemporary jazz, fusion jazz, hard bop. The rest is a mix of classic rock and more modern rock.
The streamer & DAC I decide on, or the one-box streamer/DAC will need to be great for jazz and rock.
I use Qobuz, Tidal, Radio Paradise, and ESPECIALLY JazzRadio premium streams. The streamer must be able to accept and retain a custom URL from JazzRadio. I should have mentioned this in my original post.
