Hey I'm new here... Looking to learn and read reviews and get advice on the ever evolving Home Theater system I have. My current dilemma is deciding on a 2 channel amplifier to push my main tower speakers using my Pioneer SC-25 as the central hub. What I'm trying to decide is whether I should buy a new China model class D or a used class A/B, D or H. Im looking for a minimum 150w per channel @ 8ohm, preferably over 200w per channel. Here's the kicker I'm trying to pull this off on a budget less than $325. Any suggestion?
