High end audio doesn't have to cost that much. It's more about your attitude and your willingness to be obsessive about setup and room acoustics than expensive equipment.
If you live in a metro area or near a major university Craigslist, thrift shops and estate sales can offer truly outstanding bargains. But even Audiogon will allow you to put together a great sounding system for under $1,000. Right now you could purchase a Spica, Quad, NHT, Epos, etc. bookshelf speaker for $300-500. There are refurb NAD CD/DVD receivers going for $400. That gives you enough left over for a decent speaker stand and cables and you're still under $1k.
Now will that system sound as good as a $10,000 or a $100,000 system. Probably not, but if you take the effort to set it up well, it will provide you with true high end sound.
Branislav, please explain how you can spend $15k and not obtain high end sound?
