Cool to know.
Keep in mind, raw materials are stupid expensive right now. Jeff uses Baltic Birch which is wholesaling in my neighborhood for $68 per 5x5 sheet (18mm). So you decide how much may be greed vs covering expenses.
(Keep in mind, that if he isn't building cabinets himself, then he is paying a vendor to do that for him!)
I also know his premium Drivers and Preferred Amp modules are also not... inexpensive. This all adds up for a small American Company!
