AIYIMA D03 class D amplifier "Subjective review"

[Maerlin]

If your turntable doesn't have a built-in preamp, then you'll need to get a separate turntable preamp between the turntable and the amplifier.

Of course!

Well... I only tested a des minutes with a Chromecast Audio hooked up via optical input. Strangely it seems to deliver less power than my old AKAI AM U33 (through RCA), which is given for 43W per channel into 8Ω.
Well at the moment I do not feel the 50-60W I should get with the 32V adapter.
