I have a Yamaha RX-V671 amp
( products/audio-visual/av-receivers-amps/rx/rx-v671_black_u/ )
Rated Output Power (1kHz, 1ch driven) 125W (8ohms, 0.9% THD)
Rated Output Power (1kHz, 2ch driven) 105W (8ohms, 0.9% THD)
Rated Output Power (20Hz-20kHz, 2ch driven) 90W (8ohms, 0.09% THD)
Dynamic Power per Channel (8/6/4/2 ohms) 130/170/200/240W
Matched with a B&W 684.
Nominal impedance 8Ω (minimum 3.0Ω)
Recommended amplifier power 25W - 150W into 8Ω on unclipped programme
If I don't drive the amp to about 75% of it's max volume, it sounds 'mushy' and flat. I'm not talking about bass either;not expecting much from the 684s.('Not loud enough'. This being my first hifi setup, not sure how to explain this). These are the only speakers hooked up to the amp. Bi-amping does not help much.
The question is, are the speakers and the amp, fundamentally mismatched ? Or is it some setting on the amp that needs to be tweaked ? Or is this typical for this setup ?
