I got a second disc that invokes the 'Matrix' mode on the 990. "Castaway" (Tom Hanks) dts track gets you there. Just like the platinum T2 disc...I really like this mode and enjoy it even more the neo/6...apparently if the codec is "DTS-ES" specific, the matrix mode pops up...On my old denon units I could invoke this mode on any Dolby/Dts track or choose 'non-matrix', or the usual PL/neo modes. I always enjoyed the matrix modes on those units as well. Is there some way to activate the 990's matrix mode on Dolby/Ex tracks?? Or on all DTS tracks? Processing-wise, it's no biggie. If not, too bad, I'll live. No need to attend any firmware-upgrade beggar banquets. But the matrix mode is total killer..Guess I'll roust up some more dts-es discs out there...Thanks for any help.
