The CM is great, and for my speakers I'll pick the CM over SS every time. However, my friend's shop has a Sphinx hooked up to Kingsound Prince electrostatic panels, and it just struck me as a really sweet combo. In fact it seemed a bit better of a match than the CM that was hooked up previously (the CM got sold).
I wouldn't expect that to be typical; it may be a electrostat thing -- and that being said, the panels aren't really my thing, either, though they do have their strong points. Speaker-to-amp matching does matter; were I in your shoes I'd roll the dice on the CM over the Sphinx.
Also, I have to reinforce that while the CM's (and I assume the Sphinx's) built-in phono stages are good starter or stopgap solutions, they'll increasingly become a bottleneck once you've upgraded your analog rig to say the $1K table/arm/cart level. It's very worthwhile it upgrade to an outboard stage at that point, which of course includes Rogue's own options. The 99 Magnum's built-in tube phono stage is also very good, btw, so I can't lump it in with the other built-ins.
