OK!I hope I am posting this in the correct forum! I have narrowed down my choice of "entry level" HTIB systems. Now, I would like a professional opnion. Thanks for all who respond! I was originally looking closely at the Onkyo HT-S870. I liked what it had to offer considering the price and performance. After further research I am not so sure now! The Onkyo HT-S770 seems to very similar except for the THX Select Cert. Which is better?! The S770 is much cheaper and seems to be a better buy! Is this true? What am I really getting with the THX Select Cert. Thanks a bunch for all of your professional opinions!!
