I have put a few posts in here lately to figure out what receiver I wanted to buy. This is what I got, and here is my opinion. I put the monitor out to hdmi pass through, did the audyssey set up, and put a cd im my blu-ray player. First i'll start by saying that I choice the bi amp feature to move my polks rti12 towers. DO NOT DO THIS, the amp went in to overload protection, so I shut it down and let it reset. After I fired it back up the speakers sounded wired, I thought i blew them. So I grab my old amp to see if I did, and no, I did not. I decided to hook it up with just the - + to each channel. It worked after that. It takes some one with a dr or bachelor degree to set this up.You have tweaks for everything, there are more colour opps in this amp then my tv. Also it set my normal center spk size to 60hz cross point, and had it spitting out bass. It does not sound good when watching tv. sent off an email to Onkyo and no reply yet. I had a dennon 1803 before this and i was looking forward to getting this lovely sound stage, guess what, nothing indicates that I am even getting a sound stage. I will say this, THERE is a LOT of power coming out of this receiver it moved all 6 drivers in each tower with ease. Oh ya the sound vol moves very slow, so in fact that you think somthing bad is about to happen. buy this receiver only for the power unless you work for the, isf. or something like that. Just though i'd let some of you out there know about this product. I will give 3.5 out of 5 but this is because of it's power.
