I see. I can see that the mm would command an obvious premium then. I'm less clear as to why you'd want the .2 over the .1 for it's improvements, unless you listen to a lot of SACDs or DVD-As and need the upsampling of a full track signal across the rear channels. [/quote]

Will, not sure you do see, as there will not be any rear channels for SACD/DVD-A with a .2, just front stereo pair cool

If you want a centre and rears it's an mm that is needed.
