I am about to upgrade my receiver from an older Kenwood. I would like to spend between $300 to $350. I have narrowed my choices to either Onkyo tx-sr501 ($299.) or Denon avr-1803 ( I can get this thru a friend for $330.) I need some help from the experts on this forum. Which would you choose and why? The receiver will be hooked to Cambridge Soundworks Newton series speakers in a room that measures approx. 12 x 14. Any adice would be appreciated. Thanks in advance.
