I owned Hafler stuff in the 80's-early 90's. My first real 'high-end system". Nice sounding stuff back then, not so much compared to what you can buy today, especially if it hasn't been checked for decaying electrical parts. If you own it, keep it as a good second system. But if you are looking to buy, I would agree with @jasonbourne52, for $300-400 it's a good deal, but I see prices around $600-$900. For that price for instance, a new NAD would sound better and have more modern features.
