I'm using 1000 watts into 4 ohms for my 91dB speakers. It's not a matter of speaker sensitivity or loudness, it's a matter of controlling the drivers. Speakers like Vienna Acoustics, B&W, Wilson, Dali and others have the best overall and bass response when the amp really damps and controls the large drivers, so, with these type speakers, generally more power will equal more control and better sound.
OTOH, some speakers are so efficient, approaching 100dB that you can drive the speaker with 10 watts and really control it with less than 100 watts.
What speakers are you driving?
