With the Ref 3.1 you get the full enchilada—an integrated amplifier complete with a phonostage, gorgeous cosmetics, and excellent fit and finish. In particular, take note of the attention paid to important detail such as the floating 300B tube sockets and chassis isolation feet. Much to my surprise, especially in view of its modest asking price, the Ref 3.1 turned out to be a major find, a virtual sonic jackpot in not one but several system contexts.
