I would disagree with schubert "troublesome brand since day one.'. I'm with mitch2. I bought my NAD 3130 in 1984/1985. Still have it. Used it in multiple systems, and my oldest daughter used it in college and her first year of marriage, and now it's back with me. Only problem now is some noisy controls. Will probably have these cleaned. Great little amp with lasting quality. Sounds like that's not the case for NAD these days, but I certainly can't fault my 33-yr-old for quality.
