The only difference which might be important is the different amps. The 95 has toroidal transformer, vs 93 switching amp. In my experience, the oppos are quite sensitive on power supply improvements. i have tried the modd'd ones. For some reason the digital outs improved on the Oppo when the power supply was improved...i'm no techie.
Otherwise, i [believe] you are right...most of the upgrading appears to be in the DAC and analogue output section. here is the comparison from their website.
