So while I await the arrival of the SMSL C200 DAC i ordered last week, I remembered I had a spare Apple USB-C to 3.5mm DAC dongle.
First question I wondered - is it just an electrical pin adapter, or a true DAC? A tear down confirms that despite it's small size, the Apple dongle contains the Cirrus Logic 46L06-CWZR DAC chip (https://www.cabledo.com/apple-usb-c-digi...-teardown/).
So - also keen to ensure no problems using a USB DAC with my Pi 3B (noting the USB and ethernet share bus bandwidth, although I'm using WiFi for my Pi), I ran my Pi into the USB dongle with a USB-A to USB-C adapter, which then connects via 3.5mm to RCA to 5-pin DIN to my Naim Nait 2 amp.
....and after selecting "USB-C to 3.5mm Headphone Jack A" in Moode's audio settings - it works! No clicks, pops, drop outs, and to my ears, good sound quality.
I'm still looking forward to the SMSL C200, but pleased / relieved to know the Apple DAC and Pi 3B USB are a fully working combo. Signature updated
