I think "a glorified DIY'er with poor management skills" is a good way to put it. I had a set and tried them for two months. I also had a few other AGoners come over to check them out. Everyone liked them, but not enough to buy them. It took two months and several reminders to get the grills, and ultimately I sent the grills back without opening the box.
I sent them back not only because of the grill issue and sound quality, but because in the long run I don't think they will hold their value. It seems like every set of DIs he builds is a little different... like any DIYer might do. When he makes changes to design all the time, how can you really know what you're buying?
At the end of it all, this guy has no idea how to run a business. It's too bad, because if he could focus on a good product at a good price with good service, he'd have a real long-term business. As it is now, he seems to be hanging on by his boot straps.
