This weekend I will test exactly what that means, with the RTA.
It isn't customizable at all... But it's better than bass and treble controls.
The head unit recoded today, not sure how it happened or what I did "right". But I have EQ on the iDrive now and my analog outputs are dead, and I have output from the DA2 now.
I currently have the Toslink out feeding a Helix DSP, feeding an Arc amp. No noise, no hiss, clear as day.
What is the price of this unit?
