OK this is just my opinion. I have 2 systems an HT system like your MC-1 and a 2 channel Pass Labs system balanced. On the 2 channel I have Signature XLO, but of the HT system I just have some Low-Mid Price XLO connectors and a Few AudioQuest Opals. I just don't think it matters as much on the HT system. Recreating a train crash is much easier then an intrument and I don't listen to a DVD as critically. So to answer your question an well built interconnect by AudioQuest, Tara, ect. should be fine
