  • LAMM M1.2 Reference

    LAMM M1.2 Reference

    model M1.2 Reference and model M2.2 click here for more information Model M1.2 Reference represents top of the line in LAMM hybrid and solid-state audio equipment. 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

  • LAMM M2.2 220 W class A/AB hybrid

    LAMM M2.2 220 W class A/AB hybrid

    Model M2.2 is the most powerful amplifier in the line of LAMM hybrid and solid-state audio equipment. It is one of the best creations of its designer's professional career -- a result of years of intensive research directed at attaining the most accurate reproduction of recorded music. The M2.2 is a masterful blend of design and engineering simplicity. It assures the recreation of a three dimensional sound stage in the home, recording studio, etc. without boundaries and limitations. A distinctive feature of the M2.2 is the extraordinary transparency and localization of perceived sound. It is a pure class A amplifier, with the exception of the output stage which operates in a highly biased A/AB mode. The M2.2 incorporates high-speed MOS-FET transistors in the output stage with no overall feedback. Special switch-selectable biasing circuit maintains the optimal idle current of the output stage for all load conditions between 1-16 Ohms. It is a hybrid design with the one specially selected 6922 vacuum triode. The M2.2 is conservatively rated to deliver 220 Watts into 8 and 4 Ohms in a highly biased A/AB mode (high and low impedance settings, respectively); 440 Watts into 2 Ohms, and 600 Watts into 1 Ohm (low impedance setting), continuous. The M1.2 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.

  • 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

  • Jadis JA80 single mono amplifier

    Jadis JA80 single mono amplifier

    Jadis JA80 single mono amplifier The JA80 is a power amplifier working in pure class A. It is the first amplifier created by the JADIS in 1983; it has been upgraded several times but remains the flagship of the brand. It works in a "push-pull" configuration with triple load and autobias. It can work with various types of penthodes: KT120, KT90, KT88, 6550, 6CA7 or EL34. The function phase shifter is insured by a triode double ECC82 and the function driver by an ECC83. The output transformer, guaranteed for life, allows an adaptation of impedance from 1 to 16 ohms. The cathode circuit is protected by an individual fuse. The power transformer is oversized for a better dissipation of heat and vibrations. The filtering of the high voltages is assured by high capacity capacitors. Heating the tubes is by alternate current with balance and noise reduction. Output terminals allow a bi-wiring. Gold connections assure a faithful broadcast of the signals. The device is assembled with conventional cabling "point by point" and uses a silver / copper tin solder. The frame, in 316L non-magnetic stainless steel, does not influence the electronics and renders the device unsensitive to external disturbances. Learn More
