Power amplifier model M1.2 Reference is a pinnacle of its designer’s professional career -- a result of years of intensive research directed at attaining the most accurate reproduction of recorded music. Unique topology and application of the most advanced technological resources and processes bring the M1.2 Reference to a threshold of excellence in sound reproduction. A distinctive feature of the M1.2 Reference is its presentation of the extraordinary transparency of perceived sound which in turn assures the recreation of a three dimensional soundstage in the home, recording studio, etc. without boundaries and limitations. The M1.2 Reference is a masterful blend of design and engineering simplicity. It is a pure class A amplifier featuring high-speed MOS-FET transistors in the output stage with no overall feedback and special switch-selectable bias/voltage settings for 8- or 4-Ohm operation. The bias setting switch assures the pure class A operation of the M1.2 Reference when matched with a speaker load of either 4 or 8 Ohms, whereas conventional class A designs double the power into 4 Ohms resulting in one fourth of the doubled power in class A and the rest in class AB. The M1.2 Reference is a hybrid design with one specially selected 6922 vacuum triode in the second stage.The M1.2 Reference is conservatively rated to deliver 110 Watts into 8 and 4 Ohms in pure class A operation (high and low impedance settings, respectively); 220 Watts into 2 Ohms, and 400 Watts into 1 Ohm (low impedance setting), continuous. The M1.2 Reference can drive any known speaker. The harmonic structure remains intact regardless of the speaker load, while the extreme clarity is maintained at all power levels. Each amplifier is carefully constructed and hand-crafted with the finest materials and parts currently available, some of which include military graded low noise DALE metal film resistors; PRC wire wound resistors; ELECTROCUBE and ROEDERSTEIN film capacitors; high frequency switching grade CORNELL DUBILIER electrolytic capacitors; BOURNS multi-turn potentiometers; HAMMOND filter chokes; military graded low noise long life vacuum tubes; high quality heavy duty gold-plated binding posts and RCA jacks; gold-plated NEUTRIC XLR connectors, and CAMAC-type coaxial connectors from FISCHER. Special attention was given to designing the toroidal power transformer, which has no mechanical contact with either the transformer cover or the chassis and is suspended in a special encapsulant that almost completely absorbs even the residual mechanical vibrations. This plays a significant role in assuring the absolutely unique clarity and micro-resolution during sound reproduction. The M1.2 Reference works on all world AC line voltages. Learn More

  • Cary 211 mono amplifiers

    Cary 211 mono amplifiers

    Top of the line. Cary 211M mono amplifier, used pair in excellent condition original crates and double boxes. Photos are without tubes but you get those packed separately. It is well known that using monoblock amplifiers, as opposed to both channels together as a stereo chassis, is the best way to get powerful and lifelike music. By using separate power supplies that can be much more massive, each amplifier can have more dynamic power and be quieter. Keeping two separate amplifiers also makes any inter-channel crosstalk in the amplifiers impossible, so separation is better, meaning your soundstage and musical imaging will be larger and more well-defined. The simple act of separating the two channels provides a lot of distinct advantages, but also increases the investment because of needing to double up on power supplies and chassis parts. Is this extra expense worth it? One listen to the CAD-211FE will convince you that it most certainly is. With over 70 watts of class-A power, automatically transitioning as needed to over 150 watts in class-AB, this powerhouse will effortlessly drive nearly any speaker to realistic live performance levels. It includes a bias meter on the front panel to help you maintain your amplifier at its peak operating level, and offers both XLR balanced and RCA single-ended inputs to match your system. Fully differentially-balanced construction, zero global feedback, and huge reserves of current and power mean that your system will come alive with all types of music and movies. Learn More

  • Conrad Johnson Classic 62 - 60w/ch stereo, vacuum-tube

    Conrad Johnson Classic 62 - 60w/ch stereo, vacuum-tube

    The conrad-johnson design team is committed to adapting the advances from our state-of-the-art pursuits to more affordable offerings accessible to a wider range of music lovers. This resolve is clearly evident in our new range of Classic amplifiers. Borrowing heavily on the technology of our flagship ART amplifier, the Classic amplifiers preserve the distinctive tonal character of individual instruments and voices, with each clearly located within the overall acoustical environment of the original recording. Musical transients are reproduced with realistic impact, but without artificial enhancement. Like their more costly siblings, the Classic amplifiers capture the emotional impact of the live event, never getting between the listener and the musical performance. There really is no mystery to our chosen path to outstanding musical performance: best results come from simple circuits executed with quality parts. The circuit design for the Classic amplifiers is about as simple as possible, employing just seven vacuum tubes in the Classic Sixty-Two. Single-ended triode voltage gain and inverter stages are coupled to an output stage comprised of a single pair of ultra-linear operated EL34 tubes for each channel. The Classic One-Twenty adds a second pair of output tubes to each channel to achieve twice the output power. Simple but highly effective discrete voltage regulators supply rock-solid stable DC voltage to the critical voltage gain and inverter stages. And speaking of simple, maintenance of the Classic amplifiers could hardly be easier: the owner need only make a simple bias adjustment using the built in bias indicators when installing fresh output tubes. The use of premium quality component parts is the other half of the conrad-johnson recipe for superior musicality. In this area as well, the Classic amplifiers are leaders in their class. Precision, metal-film resistors yield low noise performance for greatest clarity. Polypropylene and polystyrene capacitors, chosen to achieve a high degree of temporal accuracy, are specified for both the audio cir¬cuits and the regulated plate voltage supplies for the input and inverter stages. The result is an exceptional range of dynamics – reproducing both subtle variations in level as well as dramatic loud crescendos. Our proprietary trans-spectral wide-bandwidth output transformers contribute importantly to the extended, “airy” highs that help distinguish the Classic amplifiers from ordinary tube amplifiers. The base model Classic amplifiers offer an ideal introduction to the joys of modern tube amplifiers, while the ease of use, low maintenance costs, and reliability will be a revelation for those who have only experienced “entry-level” tube gear. Those who wish to take the experience a step further will want to investigate the upgraded Classic Sixty-Two SE and Classic One-Twenty SE amplifiers. These special edition versions upgrade the output tubes to KT120s and incorporate CJD Teflon Capacitors and ultra high-performance metal foil resistors in strategic applications in the circuit. Any of the Classic amplifier models are sure to rekindle your passion for enjoying great music in your home. Learn More
