Unsound,
That would be really interesting to insert such device in a chain spdif-in spidif-out but I would still stay out of correcting.
Timlub,
It looks like you know your caps. Outstanding Mylars? - no way (Dielectric Constant = 3). It is probably Teflon inside - who would trust Russians? (LOL) Production wise selecting caps below 1% would not be a practical solution while caps like that are very expensive (and still would make imaging a little worse). Circuit would most likely include additional buffer stage that would not make clarity any better either. Potentiometer itself has track to track mismatching about 3dB. Even expensive pots have mismatch of 1dB - still very audible tone change between channels destroying image.
The cheapest amp in Best Buy has all sorts of tone controls - often equalizer, loudness corrector, spatializer, rumble filters, noise filters, balance control etc. It is lacking one minor thing - a good sound. Same goes for many Home Theater systems - a lot of speakers but none of them good sounding.
