Disclosure - I'm a former Gryphon dealer and current Gryphon Mirage preamp owner. Among other Gryphon products, I've owned the Antileon Signature stereo and mono amps. I've not owned a Colosseum stereo or monos, but have heard the Collosseum stereo owned by Rockport Technologies on two occasions. The first was four consecutive days with the small Rockport Alyas while sharing a suite with Rockport at CES 2010. The second was more recently at Rockport's facility, through the bi-amped Arrakis system that Robert Harley wrote so favorably about. In both applications, I thought the Colosseum was outstanding. A little less "warm" than the Antileon Signature monos and with tremendous resolution and coherency. Terribly difficult to fault. Although I haven't lived with a Collosseum in my system, I'd say it belongs on anyone's short list of statement amps.
If the cost difference doesn't deter you, you may want to consider the Mirage over the Sonata pre. Both are excellent, but the Mirage is to the Colosseum, as the Sonata is to the Antileon Signature...just another level up the chain.
