which would you perfer, the nad c325bee or cambridge 540a? it would be powering a pair of paradigm monitor 7's in a room thats about 15x30 or so.
Both are quality budget amps.
The NAD may be slightly warmer sounding in the bass and mids. The Cambridge is slightly brighter quicker imho.
It is definately a case of personal tastes. Your speakers will sound different on both amps. Both are quality amps and your speakers are good enough to show the differences.
I recommend a listen.
