The bass is more SS-like than tube-like. It has really good synergy with the 3 Pi Theater Speakers and, because of their high sensitivity, can drive them to room filling levels. I have a passive attenuator I can use to match its level to the Paramours and will try it with the Amp 6 driving the Delta 12LF's and the Paramours driving the Eminence horns. I'll let you know how it sounds.
