All I know is I'm glad I got the 9000ES for about $1100 a few years ago -- with the 5 year warranty and all the goodies it's definitely WORTH buying a NEW one in this case (don't think the warranty is transferrable?). (It's usually WORTH getting a good warranty on a transport, with moving parts a breakdown is always possible -- never buy an old transport!!). My story with this is that I did all the experiments when I first got it, except as a DVD player. When I was discouraged with the 9000 for all audio except SACD, I finally tried it for DVD -- fantastic! That alone justified the purchase. But one day browsing the web, I noticed that Wright was doing mods to the 9000ES. I was curious again about it's capabilities, and since my system changed a bit since my first tests, I tried again. As stand-alone CD player, strike one (good but fairly sluggish and 2-dimens.) As transport into my MSB Link, strike 2 (better pace and dynamics but still....). As transport now with the Audio Alchemy Pro into the Link Dac, home run! Beautiful. Much better lower mids and slightly better bass than my old Proceed PDT3 transport. How could it be? Not sure why my first listens long ago didn't catch this, but now I saw at Audiorewie and here, all the comments about the 9000 as transport, and it does seem to be true. Sometimes a big corp like Sony will let a gem through the dross, and they did. My only complaint is that it clicks on and off repeatedly when you eject and then insert a CD, and I wish someone knew a way around this, so that's what I'm researching right now.
