Great deals you got, common!
I'm up to a little more than ten times that. Still not quite there IMO, but I have only a few practical steps left to take. I think my last 'wow' moment was the Audio-Technica woodies, but I managed to pick lots of holes in them (although I still have them). Since then it's been a slightly lukewarm journey of discovery. I might have given up upgrading with the CD3000, if only they were comfy for me (they weren't).
The X3000 is a gorgeous player... I loved mine and it did a great job. After I compared the X3000ES to even an XA333ES though, I realised why there are new players

The difference was quite acute. A bighter, 'faster' player definitely wouldn't hurt if you're using the HD650.
