I currently have a yamaha rx-v663 hooked up to energy RC-10's, rc-mini, take SAT surrounds, and a energy S8.2 powered sub (girlfriends living room). Power specs on the RX-V663 are:
RMS Power (8 ohms, 20Hz-20kHz) [THD] 95W x 7 [0.06%]
Dynamic Power/Channel (8/6/4/2 ohms) 130/165/195/240 W
I am thinking of picking up a denon AVR-1612 for the updated audyssey, and also the hdmi output doesnt work on the yammy, so I'd like to fix that. The power specs on the AVR-1612 are:
Rated output power: 375W (75W x 5 channels, 8 ohms, 20Hz to 20kHz, 0.08% THD);
600W (120W x 5 channels, 6 ohms, 1kHz, 0.7% THD)
On initial look at the specs, the yamaha appears to have a more robust amp section. However, the denon says it has discrete amps and I know yamaha was overestimating their power specs a while back.
Will there be a noticeable difference in the power sections of these two receivers or are they similar in power production? Just wondering if I will be losing any quality in sound with the "lower powered" denon.
Nope. Likely no noticeable difference.
