The HK 430 is a bit of an anomaly. Not all receivers of that vintage sound so good. Prevalent use of discrete componentry, oversized power supply for the design and engineers who actually listened to the product probably explains most of it.
I owned one, garage sale purchase for $20, took it home and gave it the classic Deoxit treatment. Ran it with a Nak CD player and a pair if Snell K monitors. Also ran Rogers LS3/5As, Spica TC 50s and various other monitors with satisfaction. A ridiculous product for the investment.
