Just purchased an Ayre QB-9 - I have RCA out from the DAC into 80.3 phono in. Subsequently, RCA out from 80.3 to an Anthem Statement. When using that input chain, a lot of distortion/noise is somehow added to the signal. When I go straight from DAC to amp, no problems.
On the phono input, I disabled all Audyssey processing, put it into Direct mode.. not sure what else I can do to remove processing.
