@donavabdear Hi, I use my esoteric K01XD as an external DAC through its USB or Coaxial inputs. I don't have IS2 on my system. Coincidentally we have common elements in our audio systems: JL Audio F113 and the CR-1.
The Rose 150b when I use the USB IN does not allow the USB output, so I can only use the coaxial output but that prevents me from hearing DSD, not even via DOP. Unless there is some configuration that allows it. Although auditory memory is generally poor and for a short time, the memory remains in my brain when I put in my system, like Roon Ready, the Esoteric N05 (discontinued model) and how I substantially improved the SQ of streaming. I do not perceive that feeling by placing the Rose 150B. There are subtleties in the sound, but they are minor and nothing that justifies the investment of that device in my system for now. I don't know if I'm doing something wrong in the configuration of the device. Thank you for sharing your appreciations. I am very grateful to you for it, when you suggestion in the settings will be welcome.
