Of two thing one or the other :
We define high fi by pricing...( i refuse this because i heard one million bucks system sounding bad)
Or we define it by the optimization learning process necessary to make any system/room able to reach his potential..
Why?
Because there is no relation between a system/room ,at any price, before and after the optimization process.. No relation at all... ( i suppose a minimal level of synergy already given between the gear pieces here)
I know for a fact that most people dont know what their system/room optimal level S.Q. is because they dont know how to optimize it...They prefer to buy than to learn...It takes times...If their budget is low they resign to an unsatisfying experience...
It is why they upgrade uselessly half the time to shift the pain for a moment ... The other half upgrading could be motivated by absence of budget constraint or synergy lackings...
