For those who haven't heard of Onkyo: it's a nice brand, available on the high-end sites like Crutchfield.
After doing tons of research I bought an Onkyo home theatre system (similar to this one) about 6 years ago. I've never regretted it. For new company I'll get out the T2 disk and let people hear the Terminator THX demo - it sounds amazing.
People usually want to compare speakers to Bose, since it's what they have heard of, but Bose is a company who puts a lot of money into Marketing/Hype, while companies like Onkyo quietly outperform.
If you did buy a Bose system, you'd pay more and get less awesome speakers.
