Denon has AC3, 85w/ch and plenty of bells and whistles. It's 2 yrs old and cost $1800. The A310 is only 10 months old and has component outs, AC3 and VSS. It cost $525. Both pieces are in excellent condition and were well taken care of. I have original boxes,manuals&remotes for both. Make a reasonable offer for one or both.
Also, I prefer you respond on this forum rather than my email(initially anyway)cuz if my wife finds out I upgraded, she'll be pissed. Thanks
