One well known corollary of improving one piece in the listening chain is the subsequent desire to see what sonic benefits might then come from improving other pieces as well. While I was quite happy with everything as it was when the Ulysses were the speakers, now I'm seriously looking into possible source improvements. The Apollo 11's not only significantly improve on the Ulysses, they fit with the room acoustics better; some issues I thought were room problems (through 3 sets of speakers over 12 yrs) now appear to be specific speaker/room interaction problems and have essentially disappeared. Specifically, a stereo image always slightly to the right of center and an occasionally annoying 45-55 Hz "bump" are no longer a problem. I suspect these are results of the woofer center 28-29" off the floor and the offset tweeter arrangement. I've seen a couple of rooms with big "holes" (covered and concealed, of course) in front of speakers with lower woofers to minimize "floor bounce", which I guess in my room is what the bass bump was due to; most listening rooms probably aren't quite dedicated enough to take that solution.
