I recently purchased the 205 changer. It is not fully burned in yet -- I've got about 72 hours on it. So far the sound is very smooth. Plenty of bass, lots of midrange, and appealing, though not bright, highs. One of the more coherent presentations i've heard from a CDP. My sense is that the player is getting better sounding every 10 hours or so.
I also own a 6900 integrated and there is definitely a synergy between the components. For what its worth, I find myself buying more CD's, and worrying a bit less about whether I have the best digital or not.
The changer is a bit noisy, but I have not had a changer yet, carousel or internal, that wasn't. It is no noisier than any other changer I've heard and is definitly faster than any other I have had.
