Get in touch with Dan Wright at Modswright.He has a few version of upgrades for the Sony ES line.I believe he has favorable nod in comparing his full blown 777 with $10K Accuphase.He also told me that a stock $1K Phillips has to be heard to be believed and that he is working out a few paclages on that as we speak but hasn't officially gotten it out yet.BTW the Phillips was $2K but they dropped the price in half.
