For some a $200 receiver will be the first step down the road to audiophilia; for some it may be the last purchase 'til it craps out on them. This is a great time to get into HT in one sense- never before has so little money been required to get good sound. On the other hand, long gone are the days when you could "drop out" of the hobby for a few years and return confident that you hadn't missed anything. Nowadays, you stop to blink & you'll miss a format or technology that wasn't there when last you checked. AV electronics is more complex & confusing now, and I can sympathize with the poor guy who just wants to watch his movies.
True anecdote: A few years back a good friend of mine's mom (a pretty well-to-do middle aged lady) dropped about $5k on an HT rig. Pretty nice stuff, too- Denon receiver & DVD carousel, 2 pairs of MA Silver 5i's + center, MA sub, nice Sony Trinitron tv. She had a local dealer install it for her; she actually had the guy make her a crib sheet of instructions for doing the most common things! Unfortunately, if she hit a wrong button or strayed far enough to require an understanding of the unit, she actually had to wait for her son to drop by or call his cell just to figure out how to watch tv!
So I can see why people get confused about this stuff, and it makes sense that in the Internet Age you avail yourself of others expertise. Even if you're not spending a fortune. If you shop wisely, you can even get decent sound for $200 now. Believe it or not, there's a fanatical following for one of the cheapo JVC digital receivers (available on Ebay for $179). One aquaintance over at AC even feeds his with a $4,500 digital front end! He claims it sounds better than pretty much anything he's ever had in his system.
A $4.5k CD/DAC combo, with several thousand $ of ancillary gear, driven by a $200 receiver? The times they are a-changin'!
I can see why it's exasperating to see the same questions again and again, especially the "what's the best 5.1 rack system with amps, DVD & sub for $199" ones.
People don't realize you can't buy a complete system of decent quality for the price of a VCR. And they don't seem to know how to use the 'search' feature. But I think it's a good sign overall. And if even one person asks for opinions here before buying a B(l)ose Lifestyle system, all of our headaches will have been worth it!
