"I would only recommend the Primus line if you are driving them with excessive power. The other speaker lines you are considering would likely be more forgiving with AVR power and outperform Primus. In my experience Primus is justification for a powerful dedicated amp, without it they seem anemic and thin."
If this is true, then somewhere down the line, after I get the whole system assembled, I may look into some dedicated amps. What is the best way to go about purchasing dedicated amps. Ive looked online at A4L, and even their 5 channel amps are expensive. I'm assuming it may be cheaper to just buy a 2 channel amp for my mains, then another amp for my center? As someone else mentioned on this forum in another thread, amp your mains and center and let the AVR power the surrounds?
