Conrad-Johnson Announces New Anniversary Amplifiers

2017 marks the 40th anniversary of Conrad-Johnson design inc. and to celebrate, they are introducing two new anniversary tube amplifiers – the ART150 and ART300. These amplifiers employ the recently developed KT150 output tubes.

A single pair of KT150s produces 150 Watts per channel in the ART150 stereo amplifier, while two pair produce 300 Watts in the ART300 mono-block. In addition to utilising the KT150 output tubes, the ART150 and ART300 feature new input and inverter stages using 6922s for voltage gain, main power supply reservoirs boasting a more than ten-fold increase in total capacitance compared to their earlier ART mono-blocks and ARTSA amplifiers, and a new regulator circuit for the input stage power supply.

The ART150 and ART300 have new styling, yet still show their Conrad-Johnson heritage. The output tubes are showcased behind a clear window spanning the full width of the protective tube cage, while the input tubes are in a clear protective block.

ART150s are expected to be available for delivery by mid-May, with ART300s to follow a few weeks after. As with earlier their anniversary products, production will be limited to 250 units of the ART150 and 125 pairs of the ART300. Projected US suggested retail prices are $18,500 for the ART150 and $18,000 each for the ART300s. These new models will replace the now discontinued ARTSA and ART mono-blocks.
