I have 2.2's, a much kinder load than 3.6's. I used to power them with a Classe 70, the forerunner to the 100. I substantially improved every aspect of their performance save for bass impact, extension and control by switching to a CJ MV-55 (actually, I usually prefer its bass presentation as well, finding it better balanced on most music). The CJ is rated at 45wpc, and I wouldn't attempt to use it with the 3.6's. But given my experience, if I owned 3.6's and was tube-curious, I would try to audition them using a pair of Premier 12's by all means. Let us know what you learn if you experiment. Good luck and happy listening.
