Have you tried switching the interconnects between the DAC and the preamp from right to left ? This would tell you if it is one of the cables. If the transport or digital cable were the source of the problem, i don't think that the DAC would lock onto the signal. You might also want to try plugging the output of your DAC into another input on the preamp. You could have developed problems in the one specific input or jack of that mode. Sean
