Consider checking with the Company directly.
If no one brings any TP (Thunderpants) products, or other desired products from other companies not attending, perhaps someone can contact that company to see if they might loan them a few items to bring to the Show. That way, while they may not be able to have a physical presence they can still be able to reach out to the audio community and their customer base. I'm already working on this with a few other companies letting them know their goodies will be returned after the Show.
I have just been in contact with Schiit directly and they are unfortunately unable to make the Show for some valid reasons. I have asked if they would send a few items for those interested to check out and am awaiting a response. More later.
