The newest power amplifier of Conrad-Johnson: the ART27A. Triode configured KT88s operated Class A. Fully regulated power supplies, including independent regulators for each channel’s output stage. Rated 36 Watts into 4 Ohms (the default configuration, recommended for most applications). Also available configured for 8 or 16 Ohms. Design philosophy of Conrad-Johnson : the sole legitimate function of a stereo system, from modest to state of the art, is to enable the listener to enjoy the emotional experience of music performances. Conrad-Johnson’s R&D efforts are concentrated on developing audio components which offer increasingly exact recreation of live music performances without interfering with the enjoyment of the music. This pursuit demands dedication and a genuine love of music that is impossible to hire, which explains the fact that in those few companies which succeed in producing musically satisfying components, product development is inevitably dominated by one or two individual personalities who are inextricably identified with the company.
