Conrad Johnson CA 150 Control AmplifierThe NEW Conrad Johnson CA 150 Control Amplifier has arrived at Durob Audio!

The CA150 control amplifier represents a distinctly different approach to
high-performance home audio. In many ways it is the ultimate embodiment of our
corporate design philosophy that simple circuits yield best results.

Similar in function to an integrated amplifier, a control amplifier offers the significant potential improvement of eliminating extra connections, external cabling, and inter-device connection considerations that limit conventional audio systems. But the control amplifier also eliminates an entire stage of audio circuitry (the line stage) and its inherent colorations.

The CA150 audio circuit is similar to our highly regarded MF2550 and MF2275
power amplifiers, with fet voltage gain circuit for tube-like transfer function and a high-current bi-polar output stage to achieve a high damping factor with limited negative feedback. The CA150 adds a sophisticated level control circuit that allows for precisely repeatable level and balance settings made in 1.0 dB increments.

Most integrated amplifiers not only forgo the advantage of eliminating redundant
circuits, but also are cheapened by stripping out features and sacrificing parts
quality to offer a low cost entry into a prestigious brand, thereby failing to achieve even the performance gains that could be afforded by integrating preamp and amp into a single package.

By contrast, the CA150 is a full featured control unit with seven line-level inputs including a theater loop, and its circuits incorporate the kind of top quality parts for which conrad-johnson is known. All resistors in the audio circuits and related power supplies are precision metal film types. With the exception of the large power supply reservoir capacitors (which are specially chosen electrolytic capacitors bypassed by polypropylenes), all capacitors in these circuits use polystyrene and polypropylene dielectrics. The over-sized power transformer would not seem out of place in an amplifier with much higher power rating. Even the machined gold-plated connectors have been selected for their sonic-excellence.

The use of carefully selected, high-quality parts enables the CA150 to properly
exploit the dramatic potential of a control amplifier to enhance the immediacy
of musical experience afforded by fine recordings. As a result, the CA150 is
notable for its resolution of subtle dynamic shadings and palpable imaging, for
a natural harmonic tonality, and extraordinary resolution.
