Pbb, I think that your suggestion is a good one. No need to limit it to SACD though, as it could include DVD-A multi-channel, and any other multi-channel issues that may be of interest. I don't think this conflicts with HT, as there is not necessarily any video involved.
Also, some separation like this between multi-channel users and 2-channel users may reduce the irritation between people who have strong conflicting points of view on the subject. I can tell that I am irritating to you on many posts by some of your responses, but actually I only have a strongly-held opinion, and have no "axe to grind" with you or any of the others who may differ with my "rotting in hell before listening to anything but vinyl" point of view. This is my real belief, and I recommend vinyl because I think I can help others to get better sound by going the vinyl route. Not because I strive to be an irritation to the members at large. Be that as it may, having separate categories as you suggest may reduce any friction like this that may exist between multi-channel and stereo users, as well as making the categories easier to navigate.
