yes. 6 speakers (3 pairs) is too much for 2 amp channels. at the minimum, get an impedance matching speaker switch and hook up the 3 pairs to the switch, then hook the switch to the Denon's speaker terminals.
or you could just find a cheap receiver on craigslist for $50 and use that for amplification.
