Which receiver to keep, Yamaha CR2020 or HK 630

Yamaha, without a doubt. I have the 1020 for my garage/shop system, too cheap to buy the 2020. My first Yamaha, it’s a quality piece.

Yours 105 wpc has far more power than the 30 wpc HK, and it has both MC and MM phono. Features up the kazoo.

All the meters, tuner  ... in one horizontal line, beautiful.

Mine has some kind of relay that tends to blow, hard to find (found out later).

I took my cover off, replaced all the meter lamps (wheat, not led). It's impressive inside, faceplate/controls high quality, case fits well, but fake wood wrap.
