Pardigm ps-1000 v1, paradigm 9se mk3 fronts, paradigm cc-300, and paradigm adp-150 v1 i practically stold off a guy all for 50 bucks. Insignia ns-r5101hd receiver i got for 50 bucks.My budgets low as you can tell from how much i have invested so far. I am concerned with using my current amp with these speakers since they are all 4ohms minimal 6 ohms nominal and my amps range is 6ohms-16ohms.
