Yes powered through the Audiophonics via Audiophonics PSU. Supposedly better as the Pi can't contaminate the DACs power.

I chose to power the i-Sabre V3 with separate a Meanwell SMPSU recommended by Audiophonics, whilst the Pi3 is being powered by the Aqvox LPSU.
I am a bit confused - are you saying you feed the Pi from the DAC PSU in order not to contaminate the DAC power?
So the power comes through the DAC board to power the Pi.
Yes the other way around would be better and two LPSUs even better.Powering a computer (the RPi) with a SMPS and the *analog* section of the DAC with a LPSU might make sense, not sure what the benefits of doing it the other way around are.

Did you have to switch any switches, toggle any toggles, jump any jumpers to do this? (just curious as I thought the pi by itself only needs 3volts or so, or have I mis-remembered/misunderstood?).

No. For purely digital circuits, a smps is better, as it is much better at dealing with the noise coming from high-speed digital circuits.
I thought that one shouldn't use SMPSUs at all in the mains circuit feeding the audio system...
I can try using an SMPSU with the Pi3 but I doubt it'll make an audible difference.
If your audio system has a properly designed power supply, it won't matter, but a smps is better at filtering the power supply line noise generated by digital circuitry.
I agree - pretty sure it won't make a difference, but if so, why bother with an inefficient linear supply?
power button, which enables the Pi to be turned of safely without the risk of corrupting the SD card
