Most of the exhibitors at CAF are not big brandnames with factories employing more than 100 persons. Most are highly inspired and maximally driven "ma & pa" operations like Klaus Bunge's Odyssey Audio. What is unique about Klaus is that he appears to begin designing with a very clear idea of what he wants (precision, dynamics, and laser-clear soundstages). Starting with a cost-is-no-object design, Mr. Bunge distills it over and over making it simpler and less costly each step of the way.

Stalking the halls to experience 38 rooms at Capital AudioFest in three days feels like trying to see the whole Smithsonian in one day. When I got back to my room tonight my ears were ringing from the rock-concert volume levels played in most rooms. My eyes were spinning from trying to read upside down name tags scribbled with Sharpies. But because I have been an exhibitor so many times, I remember that the most important thing I can do is recognize and respect the hope and effort (and money) all these exhibitors and organizers have invested.

A preamplifier is the port of entry through which you gain access to the sources you've so carefully assembled. It's also the gate through which all of your music passes. So while its sonic performance is obviously critical, you'd also better assess how it feels, how it looks, and how it operates—you're going to be in an intimate relationship with it for a long time. Before choosing a preamplifier, therefore, take some time to drive it around the block, or at least shake hands with it. Use your imagination as much as your ears.
