This is a giant killer. Self regulating. Auto Bias! Dual Mono pre-amplifier which will just stun. It not only sound better than most tube pre-amplifiers but it weighs more and is better built. So who says that you get what you pay for?

The glory of tubes will breathe life into your solid state amplifier. The ProLogue Three boasts tube rectification using TWO 5AR4 tubes, one for each channel. No negative feedback and no cathode followers for a vibrant midrange that creates the kind of three-dimensional soundstage rarely encountered.

Running it with a tube amp? Perfect. You will get wide bandwidth and real bass and a top end that is not bitey, but goes on forever. If you have noise issues or use high-efficiency speakers you will love it because it is so quiet. Only 11.5dB of gain and the tube heaters are DC so it will be less picky of tube choices. The power supply is perfectly de-coupled with an ultra-wideband (several MHz) constant source impedance and low corner frequency of over two octaves below the audio bandwidth (4Hz).

The ProLogue Three is non-inverting, and has two pairs of outputs so you can easily bi-amp or add a powered subwoofer. Optional ProLogue Phonostage can be added at any time.

Available with optional MM phonostage.
