has tried an amplifier with two on purpose built studio speakers and reproducing the manly acoustic registers of serious musician, with beginning to be able to go down that 20 W RMS. A global harmonic distortion was lower that 0,5 % likes alleged for Fosi, which has enabled the pleasant reproduction of any stringed instruments. A distortion of intermodulation (IMD), which confuse a sound of multiple sources, was more perceivable, especially with sets of agreements or hearts of the human voice and this was to be expected of a class D ribs of amplifier a signal of audio. In fact an IMD is present at most of some commercial speakers that has not treated the inner surfaces, he doing more difficult to distinguish a attributable quantity in an amplifier of this product by a speaker.
To appreciate a response of frequency was necessary to pose some controls of tones with some knob that signal around 3 on the dot and was mostly flat, falling sensibly only in of the frequencies way down below, down 40 Hz. A reproduction of musician of the organ of the tube was quite acceptable, included for some 32 registers of feet.
