Power is good, but keep in mind clean lower wattage power is generally better than raw wattage in a noisier, weaker piece of gear. Apologies, but I don't know anything about the NAD 314, other than NAD in general makes good stuff.
And Daryan, I think it's too early to say 35W is not enough power - it depends in large part on what speakers he's driving.
Bob - if you haven't already, check out
www.audioreview.com. Don't sweat the occasional pan over there, but if there are consistent remarks about a particular piece - either good or bad - keep 'em in mind.
FWIW, I find playback gear
much more difficult to R&D than recording gear - there are soooooo many options out there, and I'm not strong on the tech side, so in the past I've used Audioreview a lot as well as people's opinions I trust.
