I walked into a small, respectable audio specialist, asking for a receiver that would pair well with the LSi9's. I was directed to the Marantz SR5002. It's gotten great reviews. Unfortunately, I didn't realize it was an 8 ohm receiver (the polk speakers are 4 ohms). I don't know much about the technical stuff -- the store owner said the marantz would be more than enough for the LSi9's, even in a 7.1 setup. Anyone disagree with him? I wouldn't want to damage the speakers or the receiver. I do plan on pushing the system on a regular basis (I like loud music). Thanks for any responses.
