I'm looking to replace my precision power DCX 1000 mono amp with this audison amp. My PPI doesn't seem to have the clearity or the efficency I'm looking for.The numbers on the audison seem to be better than the ppi however the numbers aren't always true. So has anyone had any experience with this line from audisonor doese anyone have any suggestions. I'm looking to spend around $500 and I'm looking for a more natural sound. I'll be powering 2 IDQ version 3 dual 4 10" subs in a sealed box. Pease help!
