Sometimes, small teams are much more effecient than larger corporations. As of now, there has been no complain of Stax lagging too much behind to fullfill the orders. The SR009 is built on demand (by batches though of course), and you don't have to wait 6 months upon placing the order. The sales volume of Stax is still very small I think and I don't see a reason why they should turn into a 200 head corporation with a heavier top and less funding available for R&D for example.
For marketing, as you can see, Stax isn't spending huge amounts of money to make stupid videos illustrating the sound waves moving over the driver and this is almost always false information anyway. They make a brochure, give a couple of interviews and let the word of mouth propagate. I feel it is so refreshingly honest!
Sales network relies on distributors outside and sales agents in Japan. This is where Stax is hurting the most and some speculated that edifier could help with this. Doesn't seem to have moved much so far.
Only thing one might regret in the present state is that afaik there's a single engineer doing all the r&d. Stax develops pretty much only 1 product at a time so line refresh / new products don't turn out every 6 months. But I also appreciate this in some way. I don't want to see revisions of the 009 show up every xmas season that claim to destroy whatever product was sold before. Not that I don't appreciate innovation but simply that if you're refreshing a product every year, it probably means you should have avoided to release something half baked...
My 2cts anyway
