My Reflection Audio Quantum battery powered preamp is essentially on all the time as are the SE's. The ergonomic beauty of this setup is a very low consumption of AC at standby and the only component that needs to be turned on is the front end component to be used.
Personally, I'd stay away from tubes, A used Ayre K-1, either of the new Jeff Rowland's.
