no problem , same to you 
also i just try with the usb input of the denafrips , i can now listen all the dsd in native with default output mode and desable loopback in alsa config , i suspect it is because i did the config with the sound hardware (ian canada thing ) and i change to usb denafrips in audio output , is it possible why the loopback did not work and it output a message in a bubble : Failed to open "ALSA Default" (alsa); Error opening ALSA device "_audioout"; snd_pcm_hw_params() failed: Invalid argument
i plan to try peppyalsa with dsd64 , dsd128 , till now in usb they play perfectly in dsd native
