ok so the other day i was marveling at my PLII music decoder and how well it works and was thinking, why dont they expand the L/R sound instead? well then i found out about DSX and was like cool! so my question is, can it be used for two channel stuff with PLII (X/Z) and what is the lowest priced receiver that implements it? i dont need 11.1 because i dont use surround back (combination of space and not being impressed by them enough to implement them) so i could work with a 9.1 or even better one with pre-amp outs so i could add channels as i get the money.
