If you're going to spend 3K max on a home system I bet the Sony Htib would be a good choice and you might be able to get a PS3 with that budget+a couple of hundreds.

Power always have it's price. 6K should blow any Htibs away if you'd ask me. even on entry equips.

I started with a good amp and bought some entry speaker packages, upgrading them in stages, and I find that its becoming a Hobby to me.

Listen to a few, and compare between Htib vs. dedicated AVR+Speakers.
