Summary: I am very happy with SR6005 by Marantz. The sound is excellent. The setup was reasonably easy. The features are good for the money. I had an old Sony ES series that was a workhorse for me for years. When it finally died I was very sad. I began doing some research and a friend recommended that I check out this model. I couldn't find it in a store but I found a similar model at Best Buy and I liked it.
Summary: I've owned Onkyo for years, but my last Onkyo receiver was very underwhelming and I was ready for a change. I considered Yamaha, Anthem, Denon, and Marantz. I probably would have went with Anthem - but they require windows software for their Audio Room Correction (ARC) system, and I'm not about to install windows on my mac just for ARC.
