Hey, if most of your recordings are mediocre to bad (i.e., the music you like is generally recorded that way), why not get a system that makes them sound all right? You save some money and you enjoy the music -- isn't that what it's all about? The downside is that your good recordings may not sound as good as they could; as long as you don't buy too many good recordings, you're in great shape.
That sounds like great advice to me. A highly resolving, big-bucks audio system is going to reveal all the flaws in your recordings. If you think they sound bad now, just wait until you hear how they sound after you've spent the equivalent of a Toyota Camry on a highly resolving audiophile system.
Nevertheless, the salesman was being elitist, and more than a little rude. Shop elsewhere. But, be honest with yourself and with your salesman about the music you listen to and about your goals for your system. You may be able to get a really satisfying system by spending less. The folks who frequent AudioCircle.com are experts at this.
