coincidentally, i've long been unhappy with the denon 3300 powering my naim arriva floorstanders in my br system. i just augmented the denon with a 150w/ch parasound amp (utilizing the pre outs on the denon) and the difference is night and day--bass and overall definition is much enhanced. now, even augmenting your uncle's denon with a power amp still won't sound as good for 2 channel as replacing the denon with a good seperate preamp, but there is an obvious utility on continuing to use the denon (ht, multiroom, video switching, etc.), so i'd certainly try adding the power amp first.
