Upgrading from Onkyo 875 to separates-worth it?

I can respond since there are so few responses to date. My system used the 805 as a processor and pre-amp outs to outboard amps. It is a great processor. I don't like burning all those watts in the amps for nothing and it is not sensible ecologically, but has served its purpose. It has all the latest decoders, is bullet-proof, easy to use and I can use it down the road in another room. The 875 will have the same benefits or better. I am interested in the new Emotiva processor, due out this winter. Great company, great products and $799 new with a great warranty. If you use your system for mostly movies you might see an improvement. I use my system 90/10 music/movies, so I put my money elsewhere.

FTR, in case anyone else is wondering here, when you run a receiver without hooking into the amp section with your speakers, you are not running a load off your amps in the receiver! Unless you have a load (resistance) in the circuit using the speaker connections, they are not producing power consumption, as you are assuming here. So, you're not burning up the ecosystem so much faster, and wasting power, as you're presuming here. Yes, there's power being consumed to power the receiver, run the processing, preamp, and such, but not nearly as much power is being used as when you use the amps in the receiver. FYI.
I'm pretty sure that's right anyway. Maybe someone with differing opinion can weigh in if they know otherwise. But I'm pretty certain that's about right.

Does the receiver close the circuit to the amps , when not in use , or does it just short to ground in the same way that battery chargers do when not charging a battery but remain plugged in to the wall ? In the case of the battery chargers , they still use (waste) electricity .
Just asking as I have been considering the same set up .

Thank you .
