the Sphinx had a smooth midrange but not very dynamic in my system and bass was not good. This was with some GE Triton 1s at the time. The bass was not even very good with the 1000w amp for the speakers. When I hooked the Odyssey up bass went up major notches and everything sounded much bigger, more musical and detailed. Even though it was self powered they take on the properties of what they are being fed.
maybe with other speakers or would have been better . Dunno
