In principle I agree with your premise. Execution is another element and for some the scale solidness when patients are tested and the perceived net result is not gained. The easier thing to do is throw money at the problem.
I actually found that in my environment spending less on speakers was better. Around 20%. Moved that 10% to electronics and room 40/35 5% power and cables.
It's attention, not money, we should budget
I read with some amusement a lot of posts arguing we should spend X amount of money on speakers, or preamps or amps. I want to make a counter argument: We should budget our time and attention, not the money.
In large part because there are always bargains to be made, and MSRP has been (IMHO) a terrible guide to what an "upgrade" is, especially when considered in the context of an existing system.
30% Room
30% Speakers
5% Cables and power
35% Remaining electronics
I will read your replies thoughtfully. :)
