I have one which I won't send back for their upgrade since I've replaced it by an Accuphase DP-75. But if you do get the upgrade, I'd arrange with them NOT to use Kimber AGSS from circuit board to output RCA's, since I know from personal experience, both with my SFCD-1 and with passive preamps I've built, that 36 gauge high purity single strand silver yields a MUCH better sound. AGSS has a reputation but, by today's standards, no real sonic virtues. IMHO, of course, as hardly needs to be said. But I have listened.
