Rotarius, I'd agree with your conclusion about the Apollo, although I'd call it less 3-dimensional rather than lean. In my system, it has other appealing aspects,such as a cleanness and low noise floor. And it does play music, not merely sound.
I'm not at all sure I'm in agreement about the Cambridge player, though. (Incidentally, I see the poster mentioned the 740, and I have the 840C, so...). It differs from the NAD to my ear, in that the NAD has a very immediate presence, but not quite the same degree of inner detail. For example, while it has great microdynamics, it doesn't quite sound as though it's being played by a person. What I mean is, it doesn't reveal the "human" touch in the way that, say, an Arcam FMJ 23, which, whatever its faults, sounded as though instruments were being played by a human being. For me, that is more important than "good bass" (not that you said this), or good highs. I want to hear music made by human beings, and many components give one great sound, but without it sounding as though there's a person attached to the instrument. It is almost as though a spell was cast on the instruments, causing them to simply "play." The Cambridge, which, at 2 days, is slooooooooooooow to unfurl its abilities, sounds as though a person is touching keys, blowing, stroking, striking, and, in general, making music. Hard to quantify, but I heard live music several days a week (piano and flute) for years, and I observe a big difference between "sound-making" and "music-making." Of course, it's too early to tell, but the Cambridge has those aspects, if one listens to live music often. I'll just need to see if it increases in that ability. Time'll tell!!!
