I’ll go ahead and chime in here. I suppose the budget is a HUGE point. Not sure if you’re looking to do $500, $2k, $20k?
I had a pretty tight budget when we redid our AV setup at home, and spent a lot of time researching.
Honestly, there is no better HTIB setup than the stuff that Onkyo offers right now. I bought the HT-S5100, but if I had to do it all over again, I’d step up a couple of hundred and get the 7100. The reason being: the 5100 does HDMI video pass-through only, so I’m still using optical and coax for audio from my DVR and DVD player. The 7100 supports full HDMI connectivity.
Here are all the specs: Onkyo HT-S7100
One of the things I like most about this (both 5100, and 7100 have it) is the Audyssey 2EQ room correction. In a nutshell, you set up your system, place your speakers as best as you can, and plug in a microphone in the port in the front of the receiver. Place the mic at your best listening position in the room, and run the room correction routine. it will then send tones out of each speaker and set delay and other elements correctly. You then do this for the 2nd and 3rd best positions. Takes about 10-15 minutes.
Getting a little off-topic here: I also bought an Oppo DV981 upconverting DVD player at the same time. Outstanding unit, reads DIVX, and can play SACD’s and DVD-A’s. Take this, connect it to the unit above, get a well-produced SACD (Dire Straits’ Brothers In Arms, Pink Floyd’s Dark Side of the Moon, etc.), and prepare to be blown away.
So, I’ve got less than a grand into everything above, including good cabling for all of it, and I’d put it up against stuff I’ve heard that costs 5x as much.
