How would this sound like? New Naim5 amp, with Opera Mezza standmounts. I have a very small room, so I'm thinking of good quality small speakers and good quality small amp (2x50-60Watts). I also consider a Primare amp I21 (or the older A10) or an Audiolab 8000s, and B&W CM1 speakers. What do you think of those? What else should I look at?
