These stunning LP140M monoblocks are near mint: the only blemish is a 3/16 inch hairline scratch on one faceplate that I found only using a flashlight. These amps come with Tung-Sol 6550s and Electro Harmonix 6922s. They are Upscale Audio’s premium grade, burned in and then sold as matched sets. As a result of that and the low hours on the tubes, these amps are super quiet. I used these CJs in a tri-amp system where they served as my midrange amps, so they have had a leisurely life.
Through the PipeDream loudspeakers, these amps produced the most lifelike, three dimension image of any amp that I have used with these former Stereophile Class A speakers. This is partially due to CJs' use of Teflon capacitors.
Positive Feedback had this to say in their Writer’s Choice rave review of these amps: “The LP140M is vastly superior to much acclaimed Premier 140 stereo amplifier. In particular, there's far better bass and upper octave extension, transient attack, low level resolution and sense of space. And the LP140Ms never run out of steam or sound stressed, even when paired with the somewhat demanding Martin-Logan Summits. To fully appreciate just what Conrad and Johnson have wrought in each unit requires pairing the ART with the LP140M. To begin with, the dual mono preamp plus amplifier configuration spells less draw on the power supply and as a result, better dynamics, soundstaging, imaging and bass. More to the point, the system is only as good as the weakest point; the inclusion of Teflon capacitors in both units allows each unit to fully bloom. LPM140 amplifier.”
In addition, this is what CJ itself has to say on their website about these extraordinarily musical amps: “At conrad-johnson we are fully aware that component parts contribute importantly to the sonic performance of any circuit design. The main power supply reservoir uses a bank of massive custom polypropylene capacitors. No electrolytic capacitors are used in any of these power supplies. The LP amplifiers maintain the exacting quality standards for which conrad-johnson is internationally known. Resistors are precision laser-trimmed metal foil types. Coupling capacitors are the new Teflon CJD caps and all other audio-circuit capacitors are polystyrene, while the power supplies use large value polypropylene in parallel with polystyrene capacitors. Proprietary wide-bandwidth output transformers contribute to excellent high frequency performance. Even the machined gold plated OFC connectors and the internal wiring have been carefully selected for optimal sonic performance. Attention to details of this kind enable us to extract the full potential from our circuit designs and ensure that our products will perform to this potential for years to come.”
