I recently had a chance to leisurely compare three vintage items: an Adcom 5200 power amp, a Denon DRA-345 receiver, and an Onkyo TX-82 receiver, all around 45-50 w/ch. The Denon was very clean and had good FM performance. It was very listenable and sounded comparable to the Adcom but less dynamic. The Onkyo was warmer, muddy in the midrange, and capable of high sustained output levels but had too much coloration for critical listening. The Adcom was a quantum level above the receivers for control of woofer cone motion and presented the most articulate bass plus impeccably clean mids and highs. It's a great little amp, purportedly a Nelson Pass design. If your power needs are modest, this is a tremendous value in the vintage marketplace at under $100.
