yamaha rxv -663 vs denon avr 888

[dtowntke]

Iam lookin for an audiophilist help, ok well this is the story. I bought the Denon Avr 888 From Dakmart and was very excited for it to arrive but when it arrived it wouldn't power up, so i contacted dakmart and they said they would contact denon because it was still under warrenty and denons refurbisher united radio would fix it. i was cool with that so i had to wait for and ups shipping lable email but it took a week for me to get it so i got a little upset and told the guy at dakmart i would like a refund, he said fine he needed to contact united radio to have them ship the unit to dakmart and they would refund me, so in the mean time i went out and found the yamaha rxv 663. so to make a long story short i got the yamaha dakmart didn't contact united radio in time and the denon is being sent back to me. so my question is which is a better built reciever, i like the future proofing of the yamaha with decodin of dts hd and dobly hd but i am running a ps3 so i am not really using it. i like the idea of the presence speakers event though i havn't tried it yet. now for the denon sense it was broke when i first recieved it i havnt had time to audition it but i like the idea audyessey and i am assunming the video up conversion is better on the denon because it has the dcdi chip compared to what ever chip yamaha uses. so which is a better build, which gives better sound, basicly which one should i keep and which one should i take back, they cost me the same amount of money 450.00
