Hi, good to hear that the microphone is very good Yes I applied the correction file.

I tested Equaliser APO and Peace GUI and I didn't manage to observe any audible sound quality degradation. First I played a record from my Raspberry pi + hifi DAC+ and at the same time I started the same record on the windows pc, Peace GUI turned off, same sound level. There was no audible difference in sound. After that I turned on Peace GUI, still no difference between both systems. Then I measured both fundamental resonant frequencies using REW and added a notch filter for each individual channel. After that still no degradation of sound quality of the Windows + Peace GUI system compared to the Raspberry. So I'm convinced now that these software equalizers are quite good, at least for the low cost!

A cost of zero. The Peace GUI looks dated but it is functional. But the best bit is it isn't application specific - it works with all media player software.

Once you've used a test mic and know what is wrong with your system FR wise, I have found it to be the best method of correction. I vastly prefer it to the likes of DIRAC.

You can do things with it that aren't practical in a passive x-over. That's cool.
