Hi, I am a retired Physics and Pure Mathematics teacher from Sydney.
About 30 years ago I used to design extremely good audio amplifiers (about $10k each channel) as a sideline. I have a friend who was showing off a top shely ($500k) syatem when I was stupid enough to say "you know the best way to do this would be to have the DAC at the speaker/amp and use two synchronised DACs. Now I am trying to realise this idea using Volumio and aUDOO quad.
Sound is great so far.
