Yes, Oppo 95 is better than Oppo 103. The 103 is just a new version of the 93. If you are not buying a separate DAC, the 103 is not going to do it for you. It's a great transport with somewhat decent audio (not great).
There are a couple Marantz SA8005 units here on Audiogon for $800 each. I would chase after those first before trying Oppo.
I don't have any experience with the EVS mods. EVS replaces the I/V and buffer op amps with a single FET, which may not have enough gain/muscle to drive a good waveform. Don't know. I researched EVS before and I would be worried about the output gain issue. The single FET idea has good points and bad points.
