I have one, was using it to power a pair of these (https://www.madisoundspeakerstore.c...0e-diy-kanspea-3-full-range-speaker-kit-pair/) on a computer desk, it's ok for med to low volumes, I didn't use the DAC or BT, the main input is a Chromecast audio as a Roon endpoint, which has 3.5" analog out, and switch that with occasional computer audio output with a Schiit SYS 2 input preamp. You want a 19V or 24V DC adapter although a 12V will work for low to medium volumes. I've since replaced it with a TPA 3xxx amp, and at some point may upgrade further to a topping or smsl dac amp, maybe black friday, but currently it's fine for what it's used for.
