funny, I never heard the Cambridge Audio amplifier but I bought and returned their highly rated D500SE. Muddy, blowsy bass, weaker mids and highs than my 8 year old JVC CD player. When I got my M3Tis I got a Technics SADX 940 for under $150 to hold me over until I found my sound. (5x100 though I only used it in 2 channel mode) I had to go a long way to improve on the Technic's sound. I preferred it to the Harman Kardon AVR65 and AVR310.
Further on the subject of power - I finally ended up with the wonderful Antique Sound Labs MG S1 15 DT integrated tube amp which sounds better than the Technics, produces the most wonderful, lush yet accurate music from my M3Tis and puts out 5 watts per channel in triode mode. Yes, that's right, 5 little watts. Sourced from an Ah! Njoeb Tjoeb tube output CD player, those 5 little watts fill my living room with incredible, almost live performance sounding M3Ti music. (I use a little Velodyne 8" sub to fill in down low). Just my opinion.
