Hey everybody,
this is a thing! In general, I'm too lazy to write long reviews but this time I do so. The amplifier in question is a really great one. Telling the truth I did not expect too much for this price, but bingo! It sounds great on big speakers, with no distortion at all even on high volume. A bit more bass would be great, but finally, I put a subwoofer in business, and then it really sounded great. So all-in-all for this money, it's a good deal. I suppose it is true for all of its (real) siblings on the market.
