Possible HDMI solution for the SM?

Put a stereo preamp before the SM.

One problem with that is that tone controls affect the phases between the channels, especially at their crossover points, and that will change the locations of the sounds.

If the 3dB bass boost that I use does change the locations of the sounds, I haven't noticed it. Perhaps it is because I only use the SM to enhance stereo material. I don't use it to decode QS or SQ.
