If you DO want the ability to play SACD, I would stick with the 555 and consider tweaking it with mods and cones and better powercords, etc., etc, to stay close to your budget and get the most out of redbook and SACD. They seem to do some inexpensive but worthwhile mods to the 555 at "sacdmods.com" .If you don't care about SACD, and really just want great redbook, then for the price, you would be very pleased with a 508.24.
I owned a 333 and 555 and preferred the 555. It was rated Class A by stereophile and I think is the best SACD changer they have made - read the stereophile review - the 555 shares some of the same traits as the XA777ES. I now have an XA777ES and think it is excellent on both formats. Eventually, I will sell my XA777ES in favor of a good Universal player when one comes out that I can afford as I am starting to see some DVD-A titles that I would like to have (REM). Hope this helps,
