My system is in your options. I have the Yamaha with the M60's, QS8's, VP150 and EP175 in a 6.1 configuration. I simply love it. I like the 6.1 better than 5.1, but remember, not all movies are 6.1 right now. I'm guessing all your options will make you smile. I would definitely get a sub, since you say the setup will be mainly for ht. There's nothing like a little slam with your movies. I'm sure that you'll get some good advice on this forum. Good luck with your search.
