I am doing some research on two similar amps, and wondered what technical gurus thought was the more desireable amp:
First is the NAD 2200, 100 WPC @ 8 ohms, <120 Damping factor, +-6 DB headroom. This isn't the PE model, but I belive the power ratings are the same for that one. (The PE may have more more headroom, but I'm not certain.)
Second is NAD 2200A, 150 WPC @ 8 ohms, <100 Damping factor, +- 4 DB headroom.
Both have equal distortion rating and seem to have the same dynamic power ratings.
Are they tossups? What is more important, 50 extra WPC while giving up 2 db headroom or 50 WPC less but 2 extra DB headroom? I don't understand damping, but everything else I am clear on. Curious what the veterans think and what you would choose if you were going with one versus the other.
Continuous output power into 8 ohms 150W (17dBW) Rated distortion (THD 20Hz - 20kHz) 0.03%
Clipping power (maximum continuous power per channel) 200W
IHF Dynamic headroom at 8ohms +7dB IHF dynamic power (maximum short term power per channel)
8 ohms 400W (26dBW), 4 ohms 600W (28dBW), 2 ohms 800W (29dBW)
Damping factor (ref. 8ohms, 50Hz) >120 Input impedance 20kohms / 820pF
Input sensitivity (for rated power into 8ohms) 1.2V
Frequency response 3Hz - 100kHz / +0, -3dBdB Signal/noise ratio ref. 1W 100dB
ref. rated power >117dB THD (20Hz - 20kHz) <0.03%
