Prompt service and delivery. I am using my Allo DS with a ADI-2 DAC FS and a set of Meze Empyrean headphones. Very satisfied with the pairing and the sound quality of the Allo DS.
I have previously used a RP4 and purchased a separate DAC hat, downloading Volumio and installing it, which is easy enough. This is an important point as my Allo DS arrived well packaged, but with no instructions what so ever. If I had no prior RP4 experience, it would have been a bit of a struggle.
