OPPO BDP-93 RAM Modification Thoughts.

Just buy a 95 and forget the mod, which are never cost effective.

I would but I think the audio/video in the HDMI is same for both.

You could try giving Ric Schultz a call over at EVS (Electronic Visionary Systems - you can Google "EVS tweak"). He's 'officially' discontinued his mods of the 93 and is currently offering mods on the 95, but he may be willing to do something for your 93 if it's a small enough mod possibly. I've dealt with Ric and Kyle both, but tend to prefer Ric's approach to things as to me his mods in general seem to offer better value. But, go to his site and take a peek and you'll find his phone #.

not sure, I think the 95 modded by EVS for about the same money right now is a unbelievable. no comparison to a modded 93 but at the same time a new 95 is 1K plus 1K is 2K but it smokes my Ayre CD 5xe mp hands down in every way. I have since sold my ayre. My ayre was 6K. So far nothing I've heard in the two channel mode with any type disc gets as close to analog as the EVS modification.
But that's just my opinion and is directly related to value, it's worth 3X in sound quality easy if not more. Analog sound is expensive and hard to get right especially in digital but I guess after 40 years Ric's getting it down right addictive.
