John:
Thats what I was hoping to hear. I was really concerned about the 4ES driving the 4ohm load.

phruska:
I agree - the 4es seems like a lot of bang for the buck. I still have not thrown out the idea of getting the M60's though.

DanTana:
You are right that the Sony does not have 192/24-bit DAC's. The thing is I am not completely sure what that means! If you can fill me on what that means I would appreciate it.

Thanks to all,

Gerry
