Congrats. Mostly depends on what levels/distances but a more powerful amp can be helpful....Based on recommendations here I added a Buckeye HYPEX NC502MP this month to power a pair of Revel F208s. 4 channel, it’ll help with the C208 or the M106s too. Switching from the 110 wpc of a 9040 AVR to 350 has brought out depth and definition far more than before. Unfortunately I don’t possess the technical expertise y’all do, but it has brought pure enjoyment and appreciation.
