For 60 euros there are now excellent Digital Amplifier that are barely larger than 2 packets of cigarettes. But can such a thing sound good? A resounding yes when it comes these amplifiers. Compared with him, I have the SMSL Sa-160 and the SMSL Q5. The Sa 160 I can not rate because it is me ist.Vielleicht after one hour playing time smoked 36 Volt (included power supply) but too much for the final stages of the SA-160. The Q5 much with me by because of its hard, annoying sound in the middle. This (Sa 50) with 24 Volt power supply sounds really fine resolution. Treble and midrange Tonal are sensational to my Wharfedale Diomond. Cloudy, with 50 watts of output power it sounds in the bass a little slim, but controlled. The bass power of NAD he has not. But he also costs only a fraction of a NAD amplifier. But this resolution and smooth without aggressiveness middle: Toll. He is even after a long season not even lukewarm. As confidence grows in the long service life, since the thermal load on the components is not worth mentioning. A few more words provided. He has only an analog stereo RCA input. I have an Apple Airport Express connected via headphone jack to RCA Adabter. So I have full access to my iTunes library. These speaker terminals are necessarily banana plug is required since there is a danger in the small, fiddly connectors, the outputs are short-circuits. What the death of the chip, ie a total loss to would result because there is no protection circuit in this Digi Amp. The volume potentiometer can be fed up and turn play. A dark, bluish light illumined the potentiometer and the mechanical on and off switch. Conclusion: Amazing how much sound you get for so little money. Giants Amp power plants are of yesterday, this is the future.
