A tube lover wanting a new CD player. Can I suggest an Audio Note tubed DAC. I have the 3.1 SE and it is TRULY MAGICAL, 5687s tubed heaven.
You have the same realisation I came to, that having tubes in the path are good news for decent CD replay. However, it is not the only story.
I firmly believe you also need:
1. None Oversampling (treble smoothness to die for)
2. No Brick Wall Filter (remarkable improvement)
3. Bass texture and weight to get the blood flowing
4. Tactile and detailed bass tones
5. The famous midrange of tubes well done
6. Transformer coupled output for dynamics and load tolerance
7. Top quality caps and tantalum resistors, silver wiring.
All the above come in spades with the Audio Note DACs. And don't panic if you think they are crazy money. I went for the Kit version at Audio Note Kits (Canada). It was a breeze to build and I have a 7k+ DAC for 2k.

You could use your existing CDP as a transport, or buy a second hand CEC belt CDP for 800 US and you are done.
I use both a CDP for normal CD replay, and a Mac Mini with M2Tech EVO for my music streamer.
Ping me if you need further info.
