Denon PMA-501 Denon PMA-700

i am looking for information on the denon pma-501 and denon pma-700 amps can any one help me
Had a pma-700 amp (I think this was the model...had integrated I had). IF was same had processor loop, very large amounts of bass vs. sensitive volume control. Small speaker wire connectors in back looked like they would handle bananas but would only take bare wire or spade if you modified the connector. About 30 pounds nice heavy unit.
This is the best link I've found so far.
