Well, you didn't mention a $ figure but judging by the size of the screen it's not a small amount

But seriously, I wouldn't have a specific recommendation, but I do think that it's nice to have separate systems for music and HT

I mean, the HT system will still play 2ch, and while it won't be as optimal as a system optimized for 2ch it will still be pretty darn good and besides, you can't optimize it for 2ch with that big screen in there anyways.
Sooo...... I hate to tell people how to spend their money, but what would it look like if you refactored the same total $ and added a beefy subwoofer, switched to a 5ch amp, and got a set of 5 speakers? Maybe a slightly smaller screen. If you're into hybrid amps than maybe satfrat will chime in, I believe he has that Butler 5ch amp.
