If, as you say, 2ch music is no factor, go with the Lexicon MC-1. HTwise it is incredible. Remember, we are talking about HT, you don't want to know what I think of it for 2ch. It's hard to beleive how good this unit is for HT. If 2ch were a factor, I keep hearing great things about the CAL CL-2500 SSP. I haven't heard it yet, but there is no way it's better for HT (only) than the MC-1.
