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

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.
