I bought an Audible Illusions Mod 3 (not 3A) for $650 to use as a "stopgap" until my turn in the long Supratek line comes around. I am pairing it with solid state monoblocks and must say that it is probably the best bargain I have seen so far in high end. I considered the Rogue as well and think you would most likely be happy going in either direction. I have been delighted with the performance of the M3, which includes a very good phono stage. FWIW, I had the Vienna Beethovens in my system until I upgraded to Piega P10s. I think you will enjoy what tubes will do for the Beethovens, which are great speakers. I think you are putting together a very nice system.
For my listening tastes, mixing tubes and solid state is the way to go.
Good listening,
