I am a 61 year old guy near Boulder, Colorado, U.S.A. Just got Volumio running this week on a new Tinker Board. No HAT on Tinker Board, just running USB out to a Teac DAC/amp into Vandersteen speakers. Have it wireless playing off my NAS and also off my wife’s iTunes are her phone and iPad. I will soon hook it up to my Emotiva DAC playing through a Bryston or DIY Hypex amplifier. Speakers are DIY SEAS 6.5 in midbass and Seas 1.5 inch tweeter. I may try a HAT on the Tinker Board to see if it works.
Hiya dst, welcome to Volumio & the forums. You seem to be doing a good job integrating the Tinker Board into your home audio 
Thanks. If a newbie like me can figure this out (I am not a PC, SBC, network or digital savvy person) then I think about anyone can. Lots of fun, too!
Welcome from Lakewood.
Volumio is pretty cool, isn’t it.
