Nealhood,
I fully understand your comments on the Atmas. I have owned both the S-30 and the M-60s in the past (not for the SoundLabs, obviously). However, the biggest single push towards the possibility of the Class D amps is the ability to leave them on at all times. You see, what I did not explain was that, at this time, I'm pretty much forced to listen in short intervals of an hour or less. No amp is going to sound anywhere near its best for least 1/2 hour after a start from cold. I'm just plain tired of having to shut things down at the same time things are starting to sound good.
