I used to have an H/K Signature 2.1 amp (110 watts per ch, 5 ch.) and really liked the sound of that amp. And now it seems I should have kept it, used ones go for $850 on Amazon - I sold mine for $500 a couple years ago.
The Signature amp is better than the PA amp you are considering. You might want to consider one of the other H/K amps that have the ultra-wide bandwidth and high current capabilities. Here is a Citation 16 stereo amp that is a real beast:

I replaced my H/K with a Butler Audio TDB-5150 and it is a *great* amp. Go to ButlerAudio.com and see for yourself...
