I have been using the Rogue Dragon mono blocks for about a week now and they are doing a great job. They have those panels by the short hairs and won't let go. Are they perfect? No, not quite. I would like more air and better layering in the staging. Tube rolling time.
Any suggestions for 12AU7 tubes to accomplish that? I have a pair of Ray Select that are gutsy and textured but lack the air/staging I want. I have been rolling in my preamp (Backert Labs Rhythm). That's where the Rays were, now listing to PSVane Horizons and they are closer to what I need. I also have a pair of new production Mullards, a pair of Mazda NOS, and a pair of 5418A RCA Mil grade NOS. The tubes in the Dragons (also 12AU7) are the OEMs that come in it. Suggestions?
