Currently using a PC USB interface to Sabaj A20d 2023 (AK4191 DAC) and a Mini DSP (analog In/Out) with REW.? A believe REW accomplishes the same thing as DIRAC, but REW is a bit more of a manual? process.? At times I find the DQ-10s a bit bright.? I EQed the DQ-10 to the harmon curve and didn't like the way it sounded. It sounded a bit dull.? So, I am using the MiniDSP right now? to only integrate in my subs with the DQ10s. I may go back to full-band EQing the DQ-10s at some point.?
