Dumb question about Speaker Positioning


I have one room that is a dedicated dual purpose music room - 2 channel and Home theater. Virtually all of my home theater use is for Music DVD (concerts)and I probably 10-15% of my time in the room is video, the remainder all 2 channel listening. I need to simplify (and hopefully upgrade) my equipment in the room by installing a new 2 channel preamp with HT passthru.

Here's the question: If I optimize the positioning of the front main speakers for 2 channel music, is there any reason this wouldn't also be optimized for music video 5.1? If not would there be much compromise in the HT quality?

thanks in advance!

I second Newbee's response.
IMHO a really good 2-channel setup - two good speakers, well placed and backed up by good electronics - obviates the need for additional speakers; with the possible exception of a well integrated subwoofer.

I very strongly agree, although not everyone would. For example, one person gave the example of hearing the helicopters coming from behind him (i.e. thru the rear speakers) before they appeared on the screen in the movie, "Cliffhanger." Obviously impossible in a two channel set-up. I wouldn't really care. Others would.
Two Channel- IMO- Absolutely......Getting yourself set up in the front will give you a great perspective on where you want to go as far as "surround"...My room has been treated sonically and everything else is pretty darn good- with that in mind, i hear the "dog barking behind the shed", the "dinosaurs doing back flips"; it's all there: two channel....If you feel, hopefully after your room is treated, that you need more- then add more...

I say this without knowing the sonics in your room... Cheers, Brent
thanks everyone for the input . . . I somewhat fully subscribe to the 2 channel school of thought, but I'm still intrigued by some of the more well recorded 5.1 videos. I'm not ruling out clearing out the multi channel equipment at some point, but since I have another pure 2 channel room, I want to continue playing with the multi-purpose media space.
I've optimised the placement of my front LR speakers for stereo, and I have a center speaker and two surrounds lateral to our seating position. CD and SACD disks are played in stereo, most DVDs in 5.1. Frequencie below 80 Hz are shunted to a Velodyne HGS-15 whether in stereo or 5.1 -- I suppose stereo might be termed 2.1.

I see no reason for an either or decision in this matter; you can have both. I find that by shunting LF to the sub, the LR speakers sound a bit more open and transparent in stereo, and the sub integrates seamlessly so you would never point to it as a source, and it can deliver the subtle vibration you feel when you attend a live pipe organ recital. I like to experience the canons wizzing over my head when watching Master and Commander, so when 5.1 is available for movies or some TV shows, especially CSI: Miami which is so spectacular in HDTV, I tend to use it. But I have found audio DVDs more of a novelty than an enhancement.
