«  Amp 20 years and not a wrinkle! »

I agree with previous reviews and confirm the strength of this unit at the time. I just acquire a pair of Alesis monitor one MK2 and to feed back I get my old Technics receiver who had spent two years in a garage wet and cold and ... he left like new! So if someone gives / sells cheap copy do not hesitate, the sound quality is at the appointment.

Note: on the front it is marked "Class AA" meant, if I remember correctly, the circuits are "doubled" to ensure better sound channel (unlike the range "Class A" which was more "entry level" at the time)
