The BAT is nice, a little warm, like a Levinson but the Levinson has more bass slam, (testicular fortitude).
The Krell is the winner here but you've already had analytical sound so -----
BAT is nice, 600 is even nicer.
Pass is between the Krell and Levinson as far as balance but in a different league if detail and shadings are you forte.
McCormack os warmer and a nice amp at a great price used, if you can find one. Edge/Grypon are also nice and linear sounding.
