Oppo UDP-205 Op Amp, Linear Power Supply

IMO, before you do any surgery, try a Vibrapod 3 under each foot.  I never thought much of VPs before, but it made a substantial improvement on the 205.  It brought out a greater sense of tonality and harmonic completeness.  You probably have some lying around.  Good luck. 

I had my 205 modded by Ric Schultz of EVS. Make a noticeable difference, quieter, deeper sound stage. He did more than just the power supply.

Now I'm interested in trying the Vibrapods!

@chayro, Have you tried the Vibracones with the Vibrapods?
