An unusual "feature" on a commercial amp... crosscoupling between channels at hf.
Would anyone care to comment on this circuit in post #1 here,
If you look at the outputs left and right, each is coupled into the other channel with an RC network...
It looks like it will introduce a small amount of cross-talk that rises with frequency. Still only about -40dB at 16kHz though.
I can't imagine that's a useful or even audible tweak sonically.
Maybe it's to cancel out unwanted crosstalk introduced elsewhere (e.g by stray capacitance)?
