The super rare Denon H-5 from 1983, I'd love to see one of these up close but not blasting away at 160 watts.
Denon had really nicely designed audio, my high school friend saved for a few years and bought a full component midi-system in the 80's, it was still heavy duty and not BPC. He was bumming when CD players came out, the matching unit was ultra-expensive. Sadly I saw an AIWA All-In-One from around 86 with 600 watts! It's neat to see the older boxes where they proudly say something like 3.2 watts, going down a decimal point.
