Sony XA-7es and the 777es


Does the Sony XA-7es soundbetter than the 777es playing regular CD's? If not why can you get a second hand 777 for almost the same price as a second hand XA-7es which is much older than the 777es as well?

Anybody else have any opinions/info on the Sony 9000 es? I have a 777es and actually like it considerably, both the standard cd and SACD. Thanx, mes
I mean't to say "I've heard opposing opinions on their sonics. " One guy says A is better, the other B is better.
The guy I bought my XA7ES replaced it with an SCD-1. He said the SCD-1 sounded better for regular CD's. I've also heard a few people say the XA7 is better.
Mes, I owned 777ES and changed them to 9000ES. Ilike them (CD and SACD) much better then 7777ES, see my comment above
