Progressive Rock

Have any of you specifically built your system to listen to progressive rock, i.e. Yes, Genesis, Pink Floyd, etc.? I'm curious because I have, and was wondering what components you have found that lend themselves well to this particular type of music. The reason I asks is that I attended the Home Entertainment show last month in NYC. And not one of the rooms I visited were playing rock of any kind - and they did not seem receptive to taking request - especially at the volume I would need to hear before plunking down oh say $12,000 for a pair of speakers. Any incite you care to share is appreciated. Thanks, Matt...
