I had thought about going this route myself several times, but now I'm having Ric modify my Behringer DEQ2496 for DAC use (new D-to-A mod, chip, output stage with regulators and RCA digital in jack) in a CD-only sourced system. Ric is one of the few (VERY few) people out there on the web that I've come to have full confidence in over my past 40 years in this hobby. Whatever Ric says goes, in my book. I know him to be a problem solver on behalf of audiophiles everywhere - he looks for a good audio idea and takes it as far as it will go instead of just looking for a good 'manufacturing' idea and taking it as far as it will go, if you know what I mean. I expect to have the DEQ back by the end of the week. Have already tried his Ground Enhancers and they were excellent. You can also call Ric directly, if you haven't already. He's exceptionally forthcoming on any subject and you can get to know him pretty well that way, as I have. Sorry I don't have any direct advice with the Sony's, but I'm sure they're more than worth the price he is charging. I have the 770 myself and was facing having it modded, but went in the other direction.
