[QUOTE="Baseline, post: 930388, member: 14307"] The Kef Concerto SP-1004 are a great set of vintage speakers that are easy to drive. The fact that they are large and heavy is irrelevant as that only speaks about the cabinets. What matters are the drivers and they are quoted as having a sensitivity of 96dB and the recommended amplifier should be max 50 watts rms per channel output. I feel that 150 watts is definitely overkill in this instance and would be more comfortable using a quality amplifier with a maximum of 100 watts rms per channel output as long as the power is used judiciously. With 96dB sensitivity, a 50 watt amp would drive them with the greatest of ease. Your reserves between 50 and 100 watts would just add a little gravitas to the sound, tightening the bottom end.
