I just received literature on the Sony STR-DB1070 with 6.1 Processing and the Sony STR DE9875 with Virtual Matrix 6.1. Also included was a description of the new Pioneer VSX-D810S with 6-D Theater. Virtual Matrix 6.1, 6-channel power, 6.1 processing, 6-D Theater...oh whatever! Correct me if I'm wrong, but you don't see many low to medium-end DD/EX or DTS/ES Receivers these days. I wonder why? Maybe it's because the average consumer could care less about new surround formats...maybe it's too complicated...I don't know. If you have a DD receiver with preamp outputs, you could could connect the left and right surround preamp outputs to an old DPL receivers' CD input, for example, and then connect the rear center speakers to the left and right front speaker jacks on the DPL receiver and there you have it: homemade 6.1+1...whatever. I have an idea for a receiver: it will have virtual surround sound with eight pairs of surround speakers, 12 subwoofers, 811 DSP Modes, support DPL I, II, III, IV, Circle Surround, Square Surround, DD EX I, II, III and DTS ES, DTS ES Also, DTS ES in Virtual Mode, Cinema Mode and Confused Mode...I don't know. The whole thing will be water-cooled encased in granite...Tell you what I like to see: automatic center channel volume control. The receiver would automatically adjust the dialog between action and quiet scenes...whatever.
