Cronus Magnum is a very fine tube integrated and sounds fantastic with the right speakers to match.
HAve not heard the Sphinx hybrid yet. Need to get down to my local Rogue dealer and see if he has it. I would expect similar good results but not best performance with the same speakers as CM. CM works best with higher efficiency, higher impedance "easier to drive" speakers and also well with planars, like Magnepan. Sphinx I would expect good results with all speaker types, including smaller modern designs that are less efficient, harder to drive, and attempt to squeeze more low end bass response out of a smaller box and drivers. With planars like MAggies, either might come out on top, not quite as sure, but I would give the edge to CM.
