I'm Bi-Amping my Main Kefs with a pair of these currently and I can say they sound absolutely great, but...Can anyone tell anything about the power performance of my 4 recently aquired power amps from these numbers? Are they good performers on paper? Harmon/Kerdon PA2400 Signature Series Continuous Average Power Per Channel (FTC), from 20Hz to 20kHz both channels driven. 8 Ohms: 120 Watts @ <0.08% THD 4 Ohms: 170 Watts @ <0.08% THD Bridged (FTC), from 20Hz to 20kHz, Mono 8 Ohms 340 Watts @ <0.15% THD HK PA2400 Specs Dynamic Power (IHF, 1kHz tone burst) 8 Ohms: 150 Watts 4 Ohms: 270 Watts 2 Ohms: 440 Watts High Instantaneous Current Capacity (HCC): +/- 100 Amperes Negative Feedback: 12dB Power Bandwidth @ half-rated poutput, 8 Ohms: <10Hz - >100kHz Frequency Response @ 1Watt (+0/-3dB): 0.1Hz-250kHz Slew Rate: 280 Volts/uSec Rise Time:1.2 Volts/uSec Transient Intermodular Distortion (TIM): Unmeasureable Damping Factor: 120 Signal:Noise Ratio (ref rated power,A-wtd): 120dB Input Sensitivity/Impedance:0.8 Volts/33kOhms I'm trying to decided whether to flog 2 of them and get a 5 Channel Amp later or whether to hang on to all four for now. Thanks, Mark.
