Are there any DDDac experts that hang around in the DIY area of the forum? Had a power surge in my house last night - ever since my 3 board DDDac has distortion in the mid to HF range - the upper register of vocals are distorted for example. Seems to get worse as the sample rate gets lower? Where should I be looking to find the source. The output is via a pair of Cinemag transformers that have some 22k Mills resistors across the left and right channel to match the impedance of the pre amp I use. I measured the R load and one channel was 1530k and the other was 1860k. Could the surge have effected these?
