I've been stunned attending Jeff Beck live at Ronnie Scott's
, dts-hd & DD, via my Pioneer SC-07 in DD PL IIx Movie (NOT discrete 7.1); over Polk RTiA9 X 4, CSi5, FXiA6 X 2; in a 20 x 11 room, sofa 3' from rear; a 15" Velodyne FSR-15 yet to be included.
Impressions? I seem to have a table not far from whom a 19-YO IDed yesterday as Robert Plant. In this club venue, I'm clueless as to what 4 additional "presence" speakers would add.
This setup is a runaway from the previous 5.1, with 5 Polk RT-7s & Velodyne CT-120.
However, my recollections of Santana's Abraxas
in Quadraphonic, ~1972, are of sound fading from one corner of the room to another. This leads me to believe that an 11.1 mix MIGHT permit me to hear the ice in Plant's glass, IF the other channels were sufficiently subdued at that instant. I would imagine movie soundtracks will play up this aspect.
Where would I add 4 more speakers with WAF? Probably where the sun don't shine. IF you have in-walls, maybe. Will be curious to see how 11.1 HTIB will look on display in BB.
Oh, and the kid described the audio as best in-home he's heard (sure the 60" Kuro added something).
