@Mark, thanks, looks interesting, though I don't have enough feedback for the free demo.
@Nik, I think the Calypso I have on loan is an older model without the jumpers. Or at least they are not where people say they are. The gain *is* too high for my DAC and amp. Guess I'll ask the dealer.
I talked to Kevin at Upscale audio, and he thought a Primaluna Dialogue 3 would "smoke" the BAT (they also sell BAT). But, duh, I didn't think to ask him about the Calypso because my original question was about tube rolling the BAT (he doesn't think the dark character can be changed much.)
