They sound outstanding! Very clean and musical. Top end is crazy good. Both male and female vocals come across like they are in the room. Deep base is tight but a bit light to my taste. Overal speaker is dynamic and fast but power hungry. I'm using Marantz Ma-700 mono blocks. One per channel at 200 watts each. I think I could bi-amp them and get more out of them if I had the right cables. My pre is an arcam av9 and I use a sonos with a bryston bda-1 dac for music. I have been able to convince myself that the next upgrade will be the revel b15a sub. The WAF is about an 7-8(which is incredible in this house)partially from the sound but also because they look great. I could easily be found a week later unshaven with my hand clutching the remote, stacks of empty pizza delivery boxes and beer bottles all around. I wouldn't know what day it was. But, I love the F-52's.
