Just got my CDSA today. I have logged only 6-7 hours so far, so i don't think it would be right to offer any detailed comments. First impressions: Fit and finish is awesome. Substantial box; quality finish; silky smooth tray movement; somewhat laid back redbook playback (not at all in your face detail) -- maybe a bit too laid back, but this is likely to evolve with further use; crisp high end and smooth mids, but a bit lacking in bass punch. SACD was about 30% improvement, but tended to an overly "digital" sound. Overall, it hasn't blown me away right out of the box, and i am not rushing to re-listen to every disc that i onw. that said, it obviously is a seriously high quality machine and i expect with further use it will quickly open up.
I invite others who have had a chance to listen will tell me if they are hearing things differently.
