I'm conflicted - really want to use Rag to replace a decade-old Musical Fidelity int to drive my speakers. But that would put it way out of reach when I'm headphoning. Currently the Mjolnir is right by the couch where the volume knob is within reach, but of course that's so far from right between the speakers. A remote volume control would solve the placement dilemma, but Jason won't oblige me on that (or a balance control, grumble grumble.) So maybe longer speaker wires? I forsee a lot of equipment reshuffling in my future.
As for the tubed version of Rag, that's on-again-off-again. Maybe someone can corral Jason at THEShow Newport Beach this weekend and get the latest. But don't hold your breath.
