I have 3 different DACs in my system, including the X1. I already use the USB output from my server to another DAC. As one of my options, I. at times, willl use USB from the X1 to stream digital content to my Makua preamp DAC (Tambaqui) I can either use Roon or LUMIIN app from the X1, and I predominantly use the LUMIN app when doing this or using the X1 DAC. Roon is better interface, but sound quality, to me, is better with the LUMIN app. The idea came to me years ago when there was an associated review of using the X1 to the Tambaqui DAC, and the reviewer being very impressed with end results. I agree. I have lots of listening options with the various DACS, types of outputs, software, etc. I enjoy them all, though different. I am very happy with the X1.
