It really depends on what features you can use.
i2s, built in LPS - Magna,
Extra digital inputs, DSP, headphone amp - Studio
Front USB-A ports for say a HoliDaze flash drive - Allo or S2 Ultra
Cheapness - Raspberry Pi I will submit that I've spent more on a power supply and cables than the unit, as I've done for my desktop amp
