I’m truly sorry you had that experience. The staff in the (fairly small) room rotated between Don, myself, and the four younger people at Spatial. (Don and I were the obvious old farts.) The Spatial people were manning the room (with a nonstop 4-hour playlist+personal requests) and Don and I were there to explain the electronics, tell various origin stories, and provide comic relief.
Reviewers popped in and out, and the famous Amir from ASR even showed up for a minute or two. Crowds came in surges, particularly on Saturday, when it was jam-packed. I was not aware that anyone had emptied the room for a reviewer, that’s certainly not what I saw when I was there. They had to take their chances like anyone else. There might have been special cases after 6PM, with private showings arranged in advance, but after-6 was mostly Social Hour for the exhibitors ... for example, I dragged all of the Spatial staff and Don to hear the Songer/Whammerdyne room, just down the hall from us. I’ve been old friends with Matt Kamna, the designer of the Whammerdyne 2A3 amplifier, so that was my after-hours excuse to get them to open the door ... "hey, here’s all my friends, can we listen for a while?" ... kind of thing.
I don’t know who the Famous Name Reviewer was. I wasn’t aware of anyone dropping by, much less closing the room for them. Our plan is to build a customer base (that’s you, folks) before we let any product get formally reviewed by the magazine or YouTube reviewer. Speaking only for myself, we’d like the Big Guns to give us a little breathing room, while we get the production machine going.
Don and I already have market identities ... we’ve been doing our respective things for thirty-plus years, with our names attached to what we do. We don’t need to build something that’s already there. So I’m not in a hurry ... at all ... to get in a review queue. People have heard about the Karna since 2003, well, here it is, in a room that’s about half the size of my living room, so please make allowances.
