Hi donjr,
Thanks for the offer but I'm not in the US.
I've also considered the E600 as part of the mix (for ultimate sound out of an 'Integrated'), but the thought of heat (when I sold my CAT I managed to borrow a friend's BAT 52 preamp... and I almost cooked myself; ... I put it into the system, went away for an hour, came back to list and had to switch it out of the system half an hour later due to the heat... and it was also the middle of summer and the room had became uncomfortable to be in!), so I've shied away from class A ever since.
My listening room is small to average so class AB (with maybe a low class A component) is more the go.
