I am looking at the Onkyo 797 and Yammi v1200. I like the THX features and 7.1 ins/outs of the 797. But I like the Yammi sound and it has almost all the same features. Do you find you use the THX post-processing often or just for some DVDs or not at all? I'm just concerned that some DVDs sound too bright, and i'll need THX processing to make it sound good to me. Others are fine without it. AAAAH the decisions!
