I live in NJ and had Jerry Ozment up in CT mod my SCD 777ES to add the Audio Logic analog stage. Jerry had stopped doing it after a while, but might still be willing to do the mod on occasion. I don't know of any other modifiers in this area who are known in the business, except possibly George Kaye here in NYC (and I don't know if he does digital); if you consider Minnesota closer to home (heck, I drove there for a wedding last year, it's not that far), Steve Huntley of Great Northern Sound does mods on some digital equipment and is very well-regarded. I also know of people in our audio club who have modified their own equipment (and others') in the past quite nicely, although they aren't holding themselves out as doing this as a business and don't have the reps of Huntley, Richard Kern and Stan Warren which would be helpful when selling modded equipment.
