I wouldn't trade in the Hafler preamp; it's a wonderful machine. Its main
problem is that it looks low-tech and so it doesn't impress your friends.

I have a Hafler DH110 preamp and I absolutely love it. I am also lazy, and I
have my power amp (Hafler DH220) hidden away out of view. I solved the power
control problem by buying an ordinary 110-volt power distribution "utility
box", of the variety that you can get at any good hardware store. I removed
the switch from it, and in the spot where the switch used to be I installed
a 110-vac 40a relay. The relay actuator cord plugs into the back of my
preamp, and then all of my other audio junk plugs into the power box. The
relay provides a few seconds of time delay in both directions. Any good
electronics supply house can sell you a relay.
