My first thought when I first starting looking at a reciever was to go with the Onkyo TR606. Then, throwing monetary caution to the wind I was taken with the look, reviews and specifications of the Yamaha AX863SE. However, today I visited my local Audio-T dealer and sitting in the corner was this gorgeous Denon AVR1909. The salesman advised me that the Denon was better musically (I enjoy my music too) than the Yamaha. Also, although specced at 100watts per channel the Yamaha's actual output on a 5.1 system is nearer to 70 watts per channel. The Denon however maintains the advertised output regardless of whether a 5 or 7.1 configure is being used. I can only afford to make one purchase and I have to get it right. Can anyone help. Also, how does the Panasonic DMP BD55 compare against the Sony S550? Thanks
