Earlier models were 6 Moons integrated amp of the year, Stereophile Class B. I love mine. Mine is 15 yrs old. I am second owner and have had it now for 8 yrs. Was thinking of replacing it last year just because of age, but it is such a wonderful integrated amp that instead I had it modded by Underwood Hi-Fi. Hopefully it will serve me well for the next 15 yrs or more. A really under appreciated amp!
