Sorry, my mistake
The Pioneer 1015 is only 1S/2Z. This is similar to the Denon 486 which is a 7.1 unit. It's difficult to keep all the info straight. As I mentioned, according to the preliminary specs the 686 handles 2S/2Z, but like MDS said, we won't know for sure until we see the manual. BTW, all those units have 7 channels and they do 6.1 decoding. This is the type unit that wil work for you, but as I'm sure you're aware, more features more $$. Do you have a budget in mind?
