Tube cdp with ss units...

I have a rare, or hard-to-find, Cary CAD-855 based on the Rotel RCD-855. It is the best player I've had to date, beating out budget DACs. It is warmer and takes off the CD edge sound, but changing 12BH7 tubes and cables helps too. Some CDP I've owned were warm but not that musical to my ears (Roksan/NAD). One thing, I may be biased, but I feel my full tube setup give a more enjoyable sound, though comparable SS equipment in general can reveal more detail. As for mid-bass, my tube CDP has warmer, smoother and fuller vocals, but I cannot say it has a warmer midbass. I would change output tubes for a 'fatter' midbass such as my JJ KT88.

Try a Sonic Frontier tube dac. I have the SFD MkII, with the right tubes, you can be in heaven. I replace my ARC CD2 with the SFD MkII and never looked back.

I’d argue that your source should provide an accurate and reliable representation of the information on the disc -- at least that's my opinion. Some tube CD players, such as the Jolida JD100, use solid state op-amps for the analog output sections, then they add a couple of tubes as a "buffer" stage, in effect using tubes as a tone control.

That said, CD players do sound different (duh!), and some are warmer than others. On the warm and musical side are the new Naim CD5i-2 (the new version, not the original CD5i, which is sharper and brighter), the Rega Apollo or Saturn, and, less expensively, various Arcam models such as the CD73T (full disclosure—I have an Arcam for sale on Audiogon).

The JD-100 does not use opamps.

It is very responsive to tube rolling and could, indeed, offset an "edgy" system to some degree.

I have Audio Note DAC 2 Signature (E88CC tubes), used with Cambridge Audio 640v2 ss amp...into BRSE speakers.
I think this combo is excellent.Tubes in DAC have added warmth,naturalness and a sense of liquidity (but not too much!).Tube rolling changes MUCH, and also TWEAKING does.
Different stuff under speakers give out totally different results.
I would wholeheartadly recommend having at least something tubed in a system (CDP is a good option).
Based on my experience,at least.
