I own the Da10 and am currently awaiting Michael Elliot's new 24/96 upgrade for it, which is due out in a couple weeks. It is a very good sounding DA converter as is. I have had it for 4 years, compared it to many others, and am quite convinced it holds it's own, even with the real expensive ones. You can pick a used one up for a song and it will probably be real difficult to outdo it at current market prices. Good luck!
