We used 2 Berning 270's on Soundlab Pristine ll's several weeks ago and it was spectacular! More drive, more dynamics, more energy, just an amazing event. One ZH270 is very, very good with the Soundlabs, two is out of this world, they absolutely soar with vibrance, energy and encompass the room with sound. I've had amplifiers that weighed over 6 times as much as a single ZH270 not sound as large and in charge, I never knew anything like this was possible from such physically small amplifer. It is my opinion that the technology found in this piece is matched by no other OTL tube amplifer at this time. Anybody who's curious about some of the other unique features, just ask Tubegroover (Will), he has a manual and I'm sure he has read it by now :) However, he may have a hard time typing and reading with all the bass coming from his listening room :)
