With stock tubes (slight upgrade from Stock on Rogue, NOS RCA's) I find the Rogue to be more transparent with better and more defined bass presence, but more forward vocal range, which can come across as more aggressive. I am very sensitive to a hint of aggressive mid, though my listening buddy thinks it's worth it for the transparency (subjective choice). I figure I can't make a choice until I've put good tubes in both.
Has anyone upgraded the tubes in either unit? What results did you have? I've heard that the BAT really opens up to become more musical ("sweeter, less sterile"). Rogue and BAT users out there, what improvements have you seen? Have you compared these two preamps?
