Anybody, all dogs included, can recognized a trumpet and a piano even in the worst room and with the worst recording...Especially for a dog his master voice...
My point about the RCA dog listening the GEAR not the room even if it is a marketing genius idea for sure and a FACT, does not hinder or replace the other fact that save for headphones and gramophone pavilion at few inches of our ear we listen to a speakers/room sound not to the gear alone....Then for decades people were conditioned by electronic market method of selling the gear FORGETTING to study and improve room acoustic... 😁😊 The creation of headphones did not help room acoustic understanding for the consumers crowd of audio... 😁😊 Then they throw money for so called upgrades sometimes without end....
HiFi is the dog hearing his masters voice on the old Edison and recognizing his masters voice.. That is HiFi..
C’est la vie
And using tone control with my amplifier is no more necessary, save the loudness button at very low sound volume...
Why?
Because i can control all the acoustic factors in my the room at will with a GRID of Helmholtz adjustable resonators YES but also a grid of Helmholtz SPECIALIZED diffusers...It is NOT the same devices even if all resonators absorb some frequencies and also diffuse some....And these Helmholtz specialized diffusers are open tubes with one of their mouths filtered with some fabric cloth with variable thickness and the other stay open...And Helmholtz resonators is a volume bottle or tube CLOSED at one end with a neck of variable adjustable perimeter and length at the other end not a large open or filtering mouth like a diffuser...
Then owning a few Helmholtz resonators is not the same that owning these 2 grids...
At least thanks to you to recognize the powerful impact of the Helmholtz devices IGNORED most of the times in small room acoustic method... Panels ARE NOT ENOUGH in a dedicated room...They dont adress the pressure zones distribution...
The mere fact that we MAY feel in the obligation to modify the sound balance from a recording to an another recording or from a music genre to another music style is a SURE SIGN of an acoustic room problem or of a gear synergy problem or the two at the same time...
There is only one exception for using tone control in a well controlled dedicated acoustic room : bass head who listen only bass.... There is never enough bass in their case... They dont mind about any other acoustic factors save bass... Then they will do anything to put the emphasis on bass for sure... Here my post is for jazz listener and classical listener , not metal music or cinema listener waiting for explosions...
Sound is not music, even if music is always also sound for sure... 😁😊
My deepest respect to you...
I use the Helmholtz tuning method also. Tune the room, the electrical grid and then minor adjustment if at all with tone control. It is usually because of a source issue.
