Have had this Hitachi HA-7700 for many years. 25 years
It has really been at work and yet it keeps on sounding good
It is connected to Dynaudio ORCHESTRA for now and can take control of the pair They require muscles and get it! Probably because of the large transformer and corresponding capacitors I've had several exciting amplifiers but it is this HA 7700 coming back every time. So I think I keep it, I hope at least 25 more years
