I would take mine (if I were lucky enough to have one) straight to Ric Schultz at EVS (Electronic Visionary Systems, Calif.). He's been modding amps and digital for more than 30 yrs now I believe and I've been dealing with him for many years. He's really easy to talk to by phone about any subject and he tells me his modded 205 is easily his best yet for modding digital. I have his modded 103 and I love it and Ric says the modded 205 leaves it in the dust. I imagine you might need to prepare yourself for 'much better' than the Sony, as opposed "to as good as".
Like I say, the only reason I haven't done this myself is because I don't have a 205. If you end up wanting to sell yours, we might should talk!
