Very interesting but puts me in mind of the early days of cd when a lot of the big manufacturers insisted that they all sound the same because they all measure the same, but anyone who actually listened to them could hear huge differences. I built an elaborate linear psu to power a cheap dac after noticing huge differences with two different types of switched mode psu.

But I would LOOOOOOVE to see this articles implementation, or the future DietPi implementation compared to a Sonore microRendu or ultraRendu. I'd bet dollars to doughnuts there's no improvement with spending 20x the cash. But I'd love to see it proved.

I've been using a RPi 3 as a Roon Bridge for months and it sound great.
