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?

I've opposing opinions on sonics.
The xa7 does have variable outs and is quite a bit faster loading & playing than the 777. I've heard the 777 can take a minute to queue up. The XA7 takes a few seconds. The XA7 seems to sell for about 1100, and the 777 for 1500. I think Xa7 is the cheapest entry into a no-preamp high end system.
Today, Sony introduced SACD/DVD/CD Player 9000ES MSRP of $1.5k you can get it new for about $1,1k. Its sonics are much superior to 777ES, particularly it has "magic" midrange. Its fantastic CD Player; plus you get SACD which sound is second to live event only (much better then DVD-Audio or vinil) plus you can play 24/96 CDsn(eg Chesky), plus if you like to watch, this DVD has progressive scan, I believe first in industry (I am not sure about the later. I don't like to watch...)
Someone was just selling Sony Model DVP-S9000 units on Ebay for $1600.00. They had a gold face that was claimed to only be available on the Japanese market. MSRP was claimed to be around $2300.00. Is this an older version, or the Japanese version of this player? It was quite striking with the champagne/gold front.
