I'll post that amp's specs so you don't have to, Lowjacker, since I have the manual handy:
(The amp that Lowjacker is looking to trade is the big brother to the KAC-PS150 I have for sale....it is one of the earliest eXcelon amps from the days prior to Kenwood's upmarket gear being actually labeled as eXcelon)
Kenwood Performance Standard KAC-PS200 specs:
100w X 2 @ 4 Ohm stereo
150w X 2 @ 2 Ohm stereo
300w X 1 @ 4 Ohm stereo
S/N ratio ~ 105dB
Freq Response ~ 5Hz - 50kHz
Damping Factor @ 100Hz ~ >200
LP Filter continuously variable from 30Hz - 200Hz
Will accept a balanced input if you have a balanced output source
