Thanks for the answers!
Bignerd100, above 'fine' there are other levels of satisfaction, like 'very good', 'excelent', 'superb'.
I agree with you that the DVP-S9000ES is fine on redbook (and excelent with DVD), but I am not entirely satisfied. In a comparison with a XA7ES and a Meridian 508.24, it lost to both.
I suppose (I may be wrong) that the SCD-XA777ES is better than the CDP-XA7ES playing CD's. If do, it may be the CD-player I am seeking.
Bigtee, I live in Europe, and to modify the 9000, it would have to be a DIY kit. Also, on my country, the XA9000ES costs $4000 street price. I am looking for a all-rounder machine and not a CD Player that is magical on some types of music but fails completely on other types.
May I ask what CD-Player are you considering to replace the XA777ES? Meridian G08?
