Does anyone have any experience with these? There's a CDX-455 or something along those lines that holds 400 discs. They can be had for a couple hundred bucks and seem to have a lot of cool features like the ability to hook up a keyboard and name every disk and track for the display to show. There is an ES model that sells for about 3 times this much, but since I would be using it as a transport with digital out, I can't see paying this much just for the upgraded DAC's of the ES model. The only downside is that I would have my Zenith DVB-318 for movies, my Pio DV-578A for SACD and DVD-A, and this for all my CD's. That's starting to look like serious overkill in the ol' equipment rack. I blame David F. and Ascend for making me love music at home again. So, what do ya'll think.......worth it or not?
