I received this little Lepai about 3 months ago and was able to take into operation immediately, even though the power supply plug adaptation is a bit shaky and getting used to for our outlets him. Power supply and amplifiers operate in switch mode. From power supply No Fiep-noise can be heard and the amplifier produces a result of this innovative circuit technology no sensible heat losses at desk operation / low volume. The Lepai has a filed with blue LED volume control and a treble and bass controls. The tone control is bridged by means of direct-switch, so that when necessary gets an unadulterated audio signal to the speakers. As Speaker, I have currently turned on the little boxes from Yamaha MR040. Sufficient for this completely. For large floor-standing speakers seem a bit "steam" to be missing for powerful bass reproduction. But given the small capacity and the thin wires from the power supply, the device is probably not designed for level orgies, but adequate enough for small room sound. To my taste, the sound could still use some more heat.
