Summary: I use this receiver with my Energy Take Classic speakers and polk psw-10 sub. This thing makes full and powerful sound. Great for music for parties or just sitting back and enjoying. The ONLY thing I don't like is the remote, most remotes I can use in the dark but this one is a pain to get use to.
Pros: Accurate Controls, Easy To Set Up, Energy Efficient, Good Power Output, Great Sound Quality
Summary: I echo Surf40's review of 2/28/13. I had an Onkyo and experienced the same kind of problems. Got my Yamaha HTR-4065 at Costco for $290 just yesterday. Easy setup and it produces amazing sound through my Infinity speakers (5.1 system)- I especially like the auto speaker setup using the YPAO microphone. All information I've found indicates this AVR will produce dependable quality for many years.
Summary: First, allow me to explain what caused me to purchase this receiver. 3 years ago, I bought an Onkyo TR706 receive for $650 for its power & features. Right after the warranty period ended, static noise began emanating from my speakers. I thought that my old speakers were going kerplunk. Well, the 30 year-old speakers were just fine; the problem was my 3 year old Onkyo. As the static worsened, certain speaker channels began to break.
Summary: The sound quality is great, and sending audio from my iPhone through the AirPlay feature works even better than I expected! The energy saving aspect was also a big reason I chose this model. Yamaha did a great job with the network control feature. Beyond the pretty useful iPhone/iPad app, the protocol is simple XML over HTTP requests, which is great for people like me who want to control the receiver through home automation or scripts running on a computer.
Pros: Airplay, Energy Efficient, Good Power Output, Great Sound Quality, Network Control
