Vlumio 3 Spotify connect sounds strange

I have fresh installed Volumio 3 3.175 on Raspberry Pi 3B+ HIFiBerry DAC + with Spotify connect plugin. There is something odd happening there. It sounds almost like a polarity of one channel is reversed resulting in distorted sound something similar to ‘enhanced stereo’ but in the wrong way. This effect does not occur if the source is internet radio without any plugins so I think it might be caused by Spotify connect plugin. I wonder if it happens only in my system or it also was noticed by other Volumio users. BTW Volumio 2 did not have this problem. Thanks
