Peter, I'll chime in too here. I have a 270 with the same tube configurations as Tubegroover, running Merlin Milleniums. I'll second tubegroover's opinion on the change in sound going with the cryo'd NOS tubes from ALlan--significant change for the better. Definitely worth the money. To my ears, changing the 6JN6's made a bigger difference than changing the input tubes.
I have also noticed a major difference in going from one CD player to another--at one point I had both an ELectrocompaniet EMC-1 24/192 and a Wadia 861 to play with, and the sound could not have been more different--not that one was 'better', just different presentation. The Electro. had more bass with more 'slam', for lack of a better word, but the Wadia seemed a bit less 'bright'--not that the ELectro. was bright.
Lack of bass was never a problem with the Berning in my system, even with stock tubes. I have never been able to run the Berning in the 'low' setting, because there is just too much bass in my room. THe normal setting has really tight bass, but maybe a little too sterile in the midrange, so I usually run the Berning in the medium setting--the best compromise for my system.
Hope you get this cleared up. For what it's worth, I also have a pair of Transcendent OTL monoblocks, and they don't match up with the Berning at all (although to be fair, the tubes are getting a little old).
