For more than 20 years, conrad-johnson has sustained a reputation for producing audio components that are able to convey the emotional content of the musical experience.

From the superlative ACT-2 pre-amplifier all the way through to their PV10B pre-amplifier, and MV60SE tube amplifier, conrad-johnson have defined what tube designs of modern high-end are all about.

Premier 350 Stereo FET Amplifier

Krell FPB300c Amplifier
ACT-2 Preamplifier

 

The ACT-2 preamplifier embodies conrad-johnson's latest advances in line-stage preamplifier technology. It is the successor to the legendary ART preamplifier that has been widely recognized as the reference standard for line-stage preamplifiers since its introduction in 1996. The ACT-2 incorporates the breakthrough concept of the composite triode circuit (which has garnered more than a dozen international awards for conrad-johnson preamplifiers). The ACT-2 refines this approach by implementing circuit upgrades and by taking advantage of recent advances in materials technologies. The end result is a line-stage preamplifier that we believe will quickly be recognized as the new industry-wide reference standard.

These new conrad-johnson linear pentode amplifiers are designed to meet the needs of industry professionals and other audiophiles who require near audio perfection for their reference systems. While the demand for precision and musicality is the common denominator of these systems, the power requirements can vary considerably. To meet these varying needs, we offer the LP70S stereo amplifier rated at 70 watts per channel and the LP140M monaural amplifiers rated at 140 watts each.

LP70S / LP140M

The LP70S and LP140M share the same basic audio circuit. This circuit consists of three stages. The input signal is amplified by a triode amplifier. The signal is then direct coupled to a cathode coupled phase-inverter. This high current, triode phase-inverter stage provides a balanced, low impedance drive to the output stage. Output power is developed by 6550 output tubes, chosen for their musical accuracy, high power, and reliability. Each channel of the LP70S uses one pair of 6550s to produce 70 watts per channel, while the LP140M uses two pair to produce 140 watts per each mono chassis.

Exacting attention to detail enable conrad-johnson to extract the full potential from their circuit designs and ensure that their products will perform to this potential for years to come. Visit Sound By Singer today to hear for yourself just how true to the music an amplifier can be.
