Hi, I want to buy a receiver and after looking much into the brand names and quality and restriction of the price, I have zeroed onto three receivers. Denon AVR-1603. Pioneer- VSXD712K. Yamaha - HTR5540. Now, I want to buy the best of them, compared for sound quality, power, and ofcourse the durability. Also, I cant test it myself as I will be ordering them online and the best buy and circuit city near me doesnt keeps this product. I need to buy the product as soon as possible, So your sugggestion's would be just great.
