I have this preamp which by the way is a very nice sounding unit. It appears to put out small amounts of dc. When I measure the dc at the output of my B&K amp it is stable at 4mv. When I hook up the pre to the amp and measure at the amp out the dc measurement walks around the zero point up to about 60mv + and - and does not stabilize at any time. This is still a low total dc out and does not seem to affect the overall sound quality. It would seem the preamp is outputing small and variable dc pulses which I am sure would trigger some amps protection circuitry.
Do Audio Experience Symphonies leak DC current?
I'm thinking about trying an Audio Experience Symphonies preamp, but i read a post where someone said their symphonies pre leaked dc current, putting their classe ca-100 into protection mode.

i have a ca-200, which also does not like preamps that leak dc current (per manual).
has anyone else had this happen with this preamp, or was this case an isolated incident caused by a faulty component in the preamp?
thanks
