Being a Krell user myself (HTS 7.1), I'm not certain that you will gain much by going to the MX120... yes, McIntosh does make some really nice gear, but this seems to be a side step, not really upgrade (or downgrade for that matter).
Do you have any McIntosh dealers in your area that might have a MX120 for you to borrow home? Or can you bring you HTS2 to the dealer and do an A-B listen?
