I don't think Josh does anything other than guarantee first stocks for him with the factories. There's no expert review of such detail. They just look at it and say "good enough, let's go sell it."
Angus at least makes an effort to publish prototype pics of the PAM models and engage in constructive feedback. The PAM029M was a great example. He published pics, we provided some specific feedback, they fixed it to right specification and now the 029M is perfect. Let's hope Angus takes an interest on the SSD because quite frankly this Josh led effort (if that's even the case) has proven fruitless.
