I am having problems with a GNSC modified 381: MUCH higher than expected noise floor with frequent clicks and pops not unlike a dirty vinyl record. Incredibly, GNSC said they cannot reproduce the problem but I hear the noise in multiple sound systems in multiple locations. This 381 has been plagued since new. For what it is worth, my Wadia warranty was voided as a result of the modifications, a situation that was never discussed prior to the sale. I fear that I am stuck with this lemon. Nobody answers the phone at Wadia except a machine.
