    Fast delivery to Europe. Well packaged. Nice looking compact amp. All metal black case. Good build quality. Tested with 19V 2A DC laptop power supply, Douk Audio L1 pre-amp, Choseal banana plugs, FiiO m11 dap and Kef boxes. Good sound. Amp has enough juice. Better volume control than the Nobsound NS-20G amp.

  19. m***r

    cold metallic sound ….[ 12v ]


  20. B***v

    Excellent amplifier, with large speakers plays very clean. Natural nuance is a small power, heavy music is weak because there is not enough control. Well, at high volume it is also heavy. I took for the speakers from the computer, the volume needs a small one, so for this script is perfect


  21. T***v

    Quite a decent sound for such an usioka, most importantly, does not fly, does not wheezing, does not beep. I use with Dali Spektor 2 speakers, the sound source is a laptop. Power for these speakers behind the eyes. For games and yutuba just right.
