This was purchased via the Art of Sound Forum around 18 months ago, built by a regular of the forums (see link below to original sale thread).
A very non-digital sounding bit of kit, the most enjoyable DAC I have had so far in my system, hence this being an IC rather than a straight sale whilst I test other DACs. I have used as a Roon endpoint, but can be used with other pi-based software such as Volumio etc. The pi has a Kali Reclocker before connecting via i2s to the DDDAC, avoiding issues typically associated with USB and SPDIF connection.
A SPDIF input is also included for connecting CD player/transports/other streamers.
Prefer collection from Stratford upon Avon, or meet up/delivery as this is unboxed. I can emails pictures, there are also some on the original listing of the very tidy build.
£550 for a very good DAC and streamer .
