7 ch Preamp question

thanks bignerd, that is what i was looking for, thanks again !!

If you visit the DD-EX or DTS-ES websites you can find information on every movie release that has been encoded in those formats. There are a handfull (mainly action movies, though Punch Drunk Love was too) that are encoded.

Tangent-7.1 is completely supperfluous for teh vast majority of installations. The room is usually just not big enough to warrant it. In very large rooms I like 6.1 to fill in the rear.

what are the 6.1 or 7.1 movies available, does anyone know ?

More than 5.1 is primarily for movies. Only a very few music releases utilize more than 5.1 and none of those are discrete.

nope, i've been right here the whole time, my question was about software basically, i understand that with 7 speakers the sound can be converted from 5.1 to 6.1 or 7.1 or 8.1, etc. for that matter, my question was only regarding how much true 7.1 material is out there.

I wouldn't do anything else at this point unlsee you have a small room or cost issues. If you have a 5.1 dvd matrixing the back channels to 4 speakers fills the room that much more with sound and blends it, unless you happen to one of the few people that can have proper imaging on the rear speakers. But I haven't seen one yet they usally get thrown agenst a wall or in a cornor.

You must have been out of town a while?? ___7.1 has been written about for a couple of years. Virtually any new piece has 7.1/,and all for a good reason. It is just more involving.___ Now, yes you need the room for the extra speakers___and yes, these processors/ receivers "matrix" the 7.1 from a 5.1 source. It just depends on your desire to have a more involving experience / or not!
