WHAT I WANT IN A PLAYER
* CD, CDR, DVD, & (stereo) SACD compatible
* Optical & analog output
* Video is unimportant
* Single disc

MY RECEIVER/PLAYER
* TEAC AG-H550 (optical, coaxial & L/R analog inputs)
* Panasonic DVD/CD player, connected optically

PLAYERS I'M CONSIDERING
* Yamaha 657 ($220 $=US) & 1500 ($450)
* Denon 1920 ($300)

Within the Sterophile site you can find comments suggesting that $150 play can sound quite good and that the $4000 player is a bit better. Other comments suggest that the UPD-1 is as good or better than vastly more expensive players. Cutting hairs was a description of comparing other highend gear. I'm preparing to buy the Conrad Johnson edition of the UPD-1, but I'm having doubts before I jump. Other than speakers, how much differences are there between this stuff. Diminishing returns may be much more than I expected. With that in mind I'll probably still jump at the upgraded UPD-1.

Opinions on tweaks I made
-Removed bottom cover
-Applied some Dynamat to the under side of the plinth, the suspension brackets and arm board. (2-3hz suspension rate seams OK with the added weight)
-Used WD-40 to get the bearing out of the spindle, cleaned it and use synthetic motor oil when I put it back
-I wrapped the arm a bit (electrical tape)

Systemdek appears to have made 2 different spindle shafts. one smoth and one with a spiral groove. I assume the groove makes sure oil is moved all arouind the shaft? I use the spiral grooved one.
