This is an audiophile/videophile Coris Linear Power Supply upgrade for Oppo 203 & 205.
Brand new, never used. I purchased it back this spring and ended up going another direction with a Panasonic 9000 and never installed it in my Oppo 203.
Coris specializes in LPS's and has posts at DIY Audio, AVS Forum and What's Best Forums. Appears to be very high quality and well built.
Super simple plug and play power supply upgrade. Coris has a number of youtube vids showing step by step replacement. No permanent changes made to player.
I paid $430. Looking for $400 net to me, plus shipping at cost.


Thx
