OPPO BDP 103/105, sound quality???

"My own feeling is that, where CD players are concerned, you can hit the upper limit on sound quality at a relatively low price point--heresy for some, I know. Could the discerning ear hear the difference b/t a 103 and the 105? I doubt it. In fact, I doubt discernible sound differences between my old Sony $99 dvd player and the Oppo 103 that replaced it. I only got the Oppo for it's build quality and versatility--not only playback variety, but convenience features."

That's probably not welcome news for many folks who have sunk beaucoup bucks on high end CD players, including yours truly who spent a small fortune upgrading my own Oppo 103 to at least two levels above Nose Bleed level. 

For those with the OPPOMODS Liner Power Supply the large toroidal transformer responds very well to being wrapped in mu metal. I should also mention the circuit boards in the Oppo should be isolated against the 60 cycle hum of the toroidal transformer. This can be accomplished by mounting the transformer on cork or viscoelastic material. The bolt holding the transformer should not be tightened down all the way.  And the standoffs of the circuit boards should have small cork squares inserted where the screws are located on the circuit boards.
