It’s a (very pretty) pre-amp, not an amp. Nothing to see here, unless you’re a total “golden ears.” And to those confused by the clean rear panel, in the old days we had to walk to school — and only had two speakers in our music system. Instead of today’s 10.2 speaker systems, we just had two channels, charmingly called “Left” and “Right.” I’d tell you about the vinyl disks that held music (I know… today it’s hard to find vinyl *or* music), but you wouldn’t believe me.
