The 330 family (all the way back to the "three-thirty", IIRC, with "Nocturne" styling!) were nice, high-value pieces. I particularly like the aesthetics of the little 330c. They were quite common at my
alma mater back in the days, and, despite their low output power (20 wpc) pair(ed) nicely with the also quite common Polk Audio "Monitor 7" loudspeakers. Matt Polk is an alum of my
alma mater, so we had a certain loyalty to him and his products. Polk was really just gettin' started in those days (mid-1970s).
(Well... Gordon Miller Music, in Maryland, paired the more expensive, nicer, but barely more powerful hk430 with the Polk 7s... but the cheaper 330c was often found hooked to a pair in the real world!)
I am
sure I've said this before* (my treasure trove of stories is pretty limited!) but the hk piece I'd
love to have is the little A401 integrated amp. Since it, too, was 20 wpc, I have always presumed it's the preamp and amp of the 330c in a supremely elegant little box. Lovely bit of hardware, then and, I'd opine, still now.
rando internet photo -- and with lousy colour balance, to boot. This is a 'silver-faced' component, not
champagne.
