I listened to the same MTT/SFO Mahler 3 on the pair of LCD2 rev1 that I am borrowing and quite liked them. This was redbook layer, driven by a Dynahi (SE). I haven't noticed much difference, if any, between driving these with my Dynalo or the Dynahi, and they seem pretty easy to drive, but I have not heard them balanced. I have also not heard either the rev2s, nor much Stax gear, so YMMV.
I would not say that the LCD2 put bass where it is not in the recording, and it does seem to be well defined and not boomy whatsoever. I really enjoyed listening to the Dutoit/Montreal recording of The Planets on these as there is a considerable amount of low bass present on that recording.
