PROBLEM SOLVED - it was Enhancer!
(Enhancer info.jpg)
A week ago I made test sweeps for my diy-loudspeaker with WXC-50 feeding it analog signal. The bass sounded heavily distorted even if I had not noticed anything strange while listening to music! I thought there was something wrong with analog signal route...
So, the fancy accelerating V8 engine sound at test sweep was excessive 2nd an 3rd distortion produced by Enhancer dsp-function! Actually the info text is misleading, this feature helps small speakers to give apparently more bass, by adding heavy distorion to the bass sounds that will not be produced by speakers. I don't have a decent ADC, so I had to use my diy-speaker's output for these test. Software is REW and windowing is set to 200ms, speaker at 1m from mic at normal position in the corner. Elevated highs are necessary because I am aged with hearing loss of highs.

Then I tested Equalizer, and it has moderate effect when the unit's Volume is adjusted. Spl normalized at 1kHz in this graph.

So, please set SETTINGS2 of WXA-0 or WXC-50 to Direct for hifi listening with good loudspeakers!

Oh, I tested what loudspeaker settings and other DSP tricks in SETTINGS2 do
Loudspaker type settings make only very small changes in response, none in distortion.
Enhancer is the only setting that adds distortion!
Some single tone examples here too.
