I get exactly the opposite between IQAudio DAC and the Piano/Kali combo using MoOde, on the Piano/Kali I get about 30-40% more width/soundstage and better cleaner bass which results in more slam/kick

Did you make sure the alsamixer was set right on both setups, I know on mine that if I reboot or switch dacs I need to go back in via SSH and set the Digital output on the Piano/Kali to my preferred gain, currently set at -2.0 db on the digital setting, both analog levels set at max.
