The last receivers that have bought have always been a 7.1 system and have been rethinking this, every 7.1 cost about 25% more then a 5.1 receiver and very few movies are 6.1 yet 7.1., so why are we always leaning on a 7.1 when a 5.1 would be sufficient even on a 3d movie, what am I missing besides wasted money?

The vast majority of households likely only have a 5.1 or lower setup so if that's all you'll need then just purchase a 5.1 AVR. Keep in mind however, that on a 7.1 AVR, in addition to using the 2 extra speakers for Surr Back, depending on the AVR features, they could also be used for Front Height, Front Wide, Zone 2, Zone 3, or Front B (extra set of speakers for music listening only).

People scale video sources with different resolutions (480i, 720p) to their 1080p displays.

Likewise, people scale the number of channels in the source material to the number of speakers in their set-ups. As such, the source material doesn't have to be discrete 7.1 channels.

Consumer 7.1 pre-pros have been around since 1986. Discrete 7.1 content didn't show up till 2006. Why do you think people would buy 7.1 pre-pros 20 years before there was any 7.1 material?

Most of the new BD releases I got recently are 7.1 audio (either Dobly TrueHD 7.1 or DTS-HD MA 7.1). So 7.1 is becoming a main stream in BD releases. 7.1 alone doesn't cost that much of premium. If you look into the specs. 5.1 systems are usually the entry level budget systems with a lot of features lacking or power ratings low. So, if your budget allow, I'd pick a 7.1 system and wire it up as 5.1 for now.

Well received responses from the BIG shooters on this forum in other words the most knowledgeable, that is strange, LOL anyways guys thanks for your responses and yes with 3D and the upcoming technology and Audyssey in the past 5 years or so I agree and can always set my receivers to a 5.1 if I think that is better for my acoustic at the moment.

What you are missing is bi-amping.

My Onkyo 717 is a 7.2 AVR, but if you bi-amp (specifically built into the Onk) you get 5.1 with bi-amped mains. You cannot bi-amp 7.2 with my AVR.

Make sure your speakers are made for bi-amp as well.

Most of our clients or at least 99% want a 7.1 so they can have stereo in another zone usually the patio pool area.

Passive bi-amping like you're doing with the 717 has dubious value. Definitely a controversial subject. But if your speakers sound better to you that way then that's all that matters.

A 7.1 receiver tends to be higher in a company's product catalog than a 5.1 receiver, and also happens to have more features and more amp power than the 5.1. The extra "2.0" is usually just one of many additional features for paying more.
