What's the difference between Proceed's amplifiers

Specifically, the HPA3 vs. AMP3 and HPA2 vs AMP2.

Any insight would be great! Thanks.

I think the HP series are larger and have greater power. I have read that the HA series doesn't have quite the same sound, but I don't know that. The Amp-2 and Amp-3 are fine amps, with an excellent power band, and balanced inputs. Each channel has its own large tyroidal power transformer. db
