i'm driving CAMs with a Chord Hugo2/2go, and feeding one of Louis' subs as well from it. I have a boxed-up Hugo TT2 on the floor in front of the setup as well. The Hugo2 is plenty of drive (1W) with the sub IMHO/IME. i've used it in two different rooms now - no problemo. the TT2 and DAVE have higher power outputs, for sure, but i found the TT2's extra juice unnecessary (someday when i'm not being lazy i'll ship it back to my buddy). without the sub, i could cap out the H2 trying to get the response my brain wanted. with the sub, i push it, but don't cap it out. 70% to 90% volume range, i'd guess.
