I’m currently using a SBT to get audio from Roon into my USB DAC. It works great, with one limitation: I can’t play anything higher than 24/192 PCM or DSD64 (via DoP).
I have a spare 6th gen iPod touch which can now be a Roon endpoint and supports higher bit rates through the USB3 adaptor. That plays music fine, but I lose the convenient SBT display and IR remote.
Can I use the SBT as a Roon Remote to show me the current track info and control play/pause/skip for music playing through the iPod as Roon Endpoint to USB DAC?
