Keep the Opus 21. It's a fantastic player. Very musical and fun. As Jmcgrogan2 pointed out, both formats are DOA, though some classical labels are holding on to SACD. I tried SACD a few years ago, but a lack of software caused me to pass on. Redbook all the way and the Opus 21 is hard to beat. If you have the itch for something new try computer-based audio. Or an Audio Note transport/DAC suystem. Either will stick.
Esoteric UX-3 vs. XO-3
Has anyone compared these two players directly with one another. I have heard that the XO-3 sounds better on redbook. My other concern is the XO-3 plays cd/sacd and the UX-3 plays cd/sacd/dvd-a. My entire collection right now is redbook, but I wonder which format will emerge the winner, sacd or dvd-a. I have to admit I don't really keep up on the whole format war thing, I just enjoy the cd's I have. Can someone give me some insight on the sonic differences between these two players and also your thoughts on the format debate. I currently am using a Resolution Audio Opus 21 cdp, which sounds great. Thank you
