Amps for Dynaudio Audience 72?

I'm looking for recommendations for powering my Dynaudio Audience 72 floor-standing speakers (4 ohm). I'm open to an integrated amp or separates, but I've got a turntable so built-in phono is desirable so I don't have to buy more pieces.

Are there specific amps that are known to match well with Dynaudio?
Minimum watts?

Room size: 13 x 16 x 8 (speakers are placed along the 16' wall)
Budget: $1200 total
Music: wide range (Beethoven, Bach, Beefheart, Doc Watson, Maddy Prior, Brian Eno)
