Best DAC for RPI Roon Bridge

In your opinion whats the best DAC for RPI ?

Here is my weighted ranking of quality, usability, and price.

  1. Allo KALI + PIANO basic is my preference for overall sound quality and usability.

  2. Best vocal and low, mid, high sound detailed reproduction is Audiphonics 9018K2M, but almost no support from vendor and no drivers that would work. So, w/o major DIY mess and extra jumper cabling you can play on it only 24bit files, or must use the new Roon DSP with up-converting to 32 bit. Touch it only if you are advanced and want to waste 24 hours plus to get it up and running.

  3. Allo Boss the best sound quality today in the market for 59$.
