Equalizer in a Hi Fi system

Have spoken with dealer. I will hear this system in the next few months or less. He said Elon Musk is putting BACCH in Tesla!

Must be one helluva sophisticated DSP algorithm 

Still have concerns about that much digital processing of the original signal. There’s something elegant and simple about keeping signal pure followed by high end dac and augmenting with high end analog EQ. It’s simple and elegant.

The BACCH-SP is a computer program which cancels "crosstalk" by DSP. It is either Apple or Windows specific. It is not a preamp and does not have EQ capability. It is said to make the image more holographic. It also measures the system with microphones. The DEQX Pre 4 and Pre 8 are full function preamps with Speaker management, bass management, Room Control and EQ capability. I have not heard the BACCH-SP so I can not comment.

There is no magic with DSP. The computer has high resolution control over amplitude (volume at specific frequencies) phase and time, the time it takes for the signal to reach your ear. It controls nothing else that I am aware off although it can be used to add effects such as echo. I'll leave the effects to the artist. 

Analog is the enemy of signal purity. Again, most music is recorded digitally. Keeping it there until the final conversion to analog at the listeners DAC is the only best way to deal with it. A number can not be distorted. It can only be changed. 

Actually, the dealer at Theoretica said the BACCH SP WILL have room correction EQ capability come 2024 as well.
