BTW, to clarify on SS with subs. I actively cross at 80hz (like the Ohm subs) and level match the subs to the mains with the room analyzer and PEq in the SMS sub controller. This has the effect of "neutralizing" the warm character of the TAD amps. I'm not quite sure why, but the inherent warmth of the TADs seemed audible (though not dramatic, especially compared to full range tube amps) when the 100s are paired up full range, and -to my ear- virtually undetectable when the bass is crossed out in the fashion described above. I'm sure the "warmth" of the TADs is a frequency effect well above 80hz, but I guess the level matching and/or subwoofer output effectively masks the phenomenon.
