Pioneer Canada's website only lists one SC-9x receiver - the SC-91. In fact there are three in the range above that (95, 97, and 99) which all appear to be 9.2 channels, and all will apparently get an upgrade for DTS-X. They are shown on the US site, and are available at Canadian dealers. Why not on the Canadian site? I guess they have too many of last year's in stock.
I'm pondering the SC-95 myself. It could do 7.1.2 or 5.1.4 without external amplification, or I could use my existing receiver as an additional amp and do 7.1.4 - if I can afford the speakers and if I decide the room is big enough.
