I have not heard the Audio Valve.
I did have the Coincident 300b Mono Blocks. They are a very good SET. As good as they where, the M60's are (for my ears) incredible.
I have the amps paired with the Coincident Total Victory speaker. The speakers are expensive, but great.
One of the magazines paired the new Atma-Sphere M1 Silver Editions with the Coincident Partial Eclipse (which are one of their lowest priced speakers) and found the sound to be top notch.
