Omega speakers -- mostly sold out, all the time?

I've always been curious about Omega speakers, especially because I have tube amps.

It seems that whenever I go to their website, most of their products have a SOLD OUT banner across the speaker.

Does anyone know the backstory with Omega? Are they a company in trouble? Why would a company be mostly sold out for most models, most of the time?

I ask this respectfully and with genuine affection for a boutique builder like Omega.
