I've heard the Cremonas (not M, actually) with a Spectral combo and it was a good match; I heard the same pair (a friend of mine is the owner) with CJ's but I preferred Spectral: more "life" without losing "finesse" nor getting harsh at all. It was a DMC30 + DMA200 combo, but I guess other Spectral models could be good as well, if there is a "family sound".
Here in Italy it is a common opinion that Spectral + SF = good match (depending also on the single models).
I also heard the Olympica II + Luxman 590ax as in Hgeifman set up and yes, it was veeeery goooood. I now don't remember Cremona M's sensitivity, but if it is around 90db it could be a good match, indeed. But I guess it largely depends on room's dimensions and listening volumes: the 590ax does deliver, but 30wpc will be 30wpc.
