Excellent advice, Tim.
ProtoDAC is simple and no on-board voltage regulators, so it is very dependent on the power supply. I have used linear supplies, various SMPS, LiPO with LT1963, ultracap supply. They all sound different in terms of noise, bass, dynamics and soundstage. Describing sound is metaphorical and imprecise. Personal taste and music is different. In the end, experiencing the options for yourself is often the only way you can really know.
A ProtoDAC customer recently told me that he is using a beefy 12V linear power supply with a 5V LT1963 (this with a DIR9001 SPDIF to I2S board as a CD DAC), and it sounds very close to his Audio Note AD1865 tube DAC. Link
