I'm not sure about specific stands, but I do know that it varies with preference on the height of the speakers. Usually the fronts are at ear level and the surrounds may be a little higher than ear level towed in and down a bit. You can't go wrong with having them all at ear level. I recommend trying out a few different set-ups and keep what you enjoy most. I can't notice too much of a difference with my speaker set-up. I tried towing in my fronts, moving them farther apart, towing in the surrounds, facing them more down, etc. I don't think I have enough experience with speaker set-ups for my ears to notice small changes in the speaker set-up. I know some here can really tell- too each their own!

Good luck and enjoy!
