Why I sold my $50,000 DAC ...

Acoustics rules audio engineering...

Synergy matter if you dont have synergy you dont have anything to optimize...

But when the gear parts are bought, synergetically, the real work begins...

Mechanical,electrical,and acoustical optimization, will also implicate tweaking optimization even modification of gear (especially in low cost system, nobody modify in a homemade style a 100,000 bucks speakers) ..

Now think about that :  there is no relation between a system/room  S.Q. BEFORE versus AFTER well done optimization. It is like day and night.

This illustrate why price paid means not as much as people think... 

For those who need precision, my axiom did not imply that a low cost system/room will rival a much costlier system. It could be possible though when a relatively low cost system is very well optimized versus a very costly system but not optimized at all ...

But  if optimization make a system /room to reach is peak working level it cannot change the basic design constraints...

Thanks to the OP for the interesting article 

@ Deep_333 lets not forget D&B also as i have worked with all the major line array systems

being  a sound person in professional Concert  P.A Systems, also anyone  else that has been there a while remembers the Old S4 speakers at aprox 425 lbs ea. not to mention the new sttyle Digital Mixing boards and amp racks that are adjusted just by changing the IP addressing in unnder 10 minutes.

Room treatments, set up and synergy, the 3 main ingredients necessary for good sound IMO. 

Great read, and oh so true!

I think I have said it over 1599 times...the room is as important as the gear.
