IMHO Stax have a reputation of delivering their products at the best price they can afford. This is what explains their tendency to bankrupt. Their products are as reliable and well built as it gets. More competition wouldn't mean cheaper-better products, but perhaps right the opposite, worse products made at lower cost and using poorer materials and QC at the same prices, so profit is larger with lower sales.
I may be wrong but electrostats, needing dedicated specialty amps which can't be shared to drive cheap dynamic headphones, aren't going to become a consumer market thing no matter how good and cheap you can sell them. If not why isn't people going nuts getting a 207/252S combo, when it outperforms most mid budget dynamic combos? I see Stax as Linux, something that is good, but that if you don't try and face some restrictions and difficulties, you won't get to know how good it really is.
