Good amplifier, clear sound. High efficiency. Use this with a 19 volt laptop supply with max current of 3.5 ampere and output power of two times 25 watt is easily possible thanks to the high efficiency. Remarkable low radio interference on medium wave and other AM frequencies! Stays cold/cool with higher output. Good choice also for Li-Ion (4 cells in series) and portable use. Frequency range 19 Hz to 25 kHz zero dB when loaded with resistor. Some deviation of frequency response with complex load, up to max plus and minus 2 dB in the 10 to 16 kHz range with some speakers. Happy with the small size too. Recommended.
