Recommendation of a good nearfield speaker

"Less power, less noise, more music. Make sense?" Not really, high sensitivity speakers are prone to let more noise in and through. Why would there be more music? Low powered amps (500 mW) will have less headroom and will probably clip sooner. Many active speakers still have XO's.

Look into the Omega line of speakers. They are a high eff. single driver design. Give Louis at Omega a call. He will set you up right.
