Damping factor is irrelevant. Read a post I threw on here a while back about it. It means nothing. You can fake damping factor so easily its not funny, and really not worth caring about!!! Also, Class D damping factors are actually measured differently, so you cannot compare to other classes.
And ALL amplifiers produce THD at 10%. It happens when you exceed rail voltage. Power is meant to be measured at 1% THD, so when you push the amplifier hard enough, it will start to produce higher numbers.
Either way, WHO CARES?!? Seriously, Harmonic Distortion produced by Amplifiers shy in comparison to that same distortion produced by THE SPEAKER ITSELF!!! Seriously, the speaker is the greatest producer of distortion in the audio chain, so why dont we care more about that?!
There is nothing wrong with the PDX amps, nothing wrong with the Audison, nothing wrong with DD etc. etc. You choose the amp that you believe provides you with what you are looking for. If its a clean signal, I can assure you that most Jaycar amps fit the bill nicely.
