by the way I absolutely agree it is a very different. Room EQ and Tone Control have nothing to do with each other, ultimately room correction comes first to ensure a theorically sound room and a tone control system comes second for the music. But we all have to remember that music is the ultimate goal, if the recording is badly balanced, no room correction will help. TaCT does the job apparently in digital form before the DAC (I think it is the ideal solution).
I've got tone control and it is of great help to clear out the mud of some recordings or to put the balance straight of some.
Jamiroquai is a great example of recording with no high frequencies, only 120-5k. on a different cateogry, Diana Krall as well is very badly done even with an emmy award for sound engineering....
