I will eventually post a complete review, but a few comments:
I briefly listened to the headphone output with my very modest Grado SR-60 cans. It sounded pretty good, better than the headphone outputs on my CD recorder (a Marantz CDR-632) and my DAC (a highly modded Beresford 7510 with an unmodded headphone jack). Full, clean sound with a nice liquid midrange. IIRC, the C220 does have the tubes in the signal chain of the headphone output.
The phono section is surprisingly good (MM only). Very smooth, detailed and it seems to de-emphasize surface noise without dulling the treble range. This is all in comparison to my previous preamp, a Conrad-Johnson PV-11 with phono stage (it had some performance issues).
Check my system link. It is up to date. I am really enjoying this system. I can't say for sure I will never upgrade any of it, but I am focusing mainly on upgrading things like cables and isolation for the time being.
No on the remote tone controls. You can do mute, balance, volume and a few set up functions via remote. To get remote tone controls, you're stepping up to the C2300 (a significant jump in price). Or, step down to the Parasound Halo I mentioned, which has remote tone control and defeat selection on the remote. In any case, the C220 tone controls are subtle but useful, and do not seem to have any negative impact on the sound when engaged.
The C220 does have three sets of main outputs, if that is helpful.
My only criticisms so far is that the phono section gets a little noisy at higher volume settings. Not horribly so, but noticeable. Some have mentioned that different tubes can help with this. Also, the soundstage width, while decent, is not huge. But when the source material calls for it, it does image and soundstage fairly well. It might have a tad less "tube bloom" than the Connie-J did, but overall, I like it better. Mids, especially voices, to die for. No etch or glare, even on mediocre source material.
