So also MOST based. Amplifier in the left rear. At least this means I can pickup on the speaker wires going to each of the locations if I wanted to replace the amp. I suspect the only option is to leave the existing amplifier in place to act as a convertor from MOST to 'analog' and then using something like a BitONE unit, try and clean this signal up and then push that back into a new amplifier.
