I disagree with you. The difference between boutique and a full blown brand is considerably big when it comes to such a specific domain like Audio.
Senns and AKGs have enough of a commercial aura to make products that cater to a not so bothersome consumer( like CX-180s and AKG K311s) and also to the elite customers(like HD700s), out of their vast history and their ability to invest - while you will not see Woo Audio or Audiostatic making non-competitive products to cater to such consumers because their capital is invested with the promise of big returns and the motive of breaking even....
What I mean to say is Brand have the power and money to cater to everyone while it is not the same with Boutique Woo Audio. But 10 years down the line, niether you nor I can guarantee that Woo Audio will have made enough profit to enter lower/budget consumer markets or become a 'Brand'
Yes, India is in fact very small a market for Audio Manufacturing but there are some really amazing Speaker manufacturers like Cadence Audio who have a good repute even in the states.
