^^^^^^^ Regarding the extended warranty. I believe SQ runs in conjunction with manufacturer warranty. The most you can do is 3 years, so you are going to pay ~$60 for one extra year. Keep in mind, if you bought your AVR on AmEx, you have any extra year with them for a total of 3.
Hooked mine up last night and the basics are working. It was too late to really get into the manual, but the only hiccup so far is the internet radio. My wireless media adapter was working when I set it up with a laptop, and on the Yamaha, the network settings said it had an IP address, so it appeared networking was up and running. I also could see my fiancee's Windows 7 laptop in the networking tab. Yet when I selected V-Tuner, I got nothing. I'll dig into the manual tonight.
I ran YPAO and it set my Monitor BX6 towers as small. I am not using a sub right now, as the budget needs to recover from the AVR and front three speakers being purchased. I switched it back to large, as I figure I want the towers to get as much low frequency as possible. They go down to 34hz, so response range shouldn't be an issue.
Anyway, it looks like I have a lot of learning to do tonight with the manual. At least I haven't run into anything that is truly "broken" yet.
Is anyone finding their 867 gets real hot? I was going to put it in the cabinet once I test everything connected to it, but if it is going to get way too hot, I might just leave it out until my cooling fans arrive. I only ran it for like 40 minutes last night and it was just slightly warm to the touch, but it was enclosed either. Nor was it being pushed since it was 9:30PM and I live in a townhome.
