no longer for sale

This highly-acclaimed and sought-after preamplifier has been very lightly used, meticulously maintained and is in excellent/mint condition. Please see the attached pictures.

It is one of those rare units for me that makes listening to music even more pleasing. For many reviews and detailed specifications on this truly world-class sounding preamplifier, please visit the official website page below.

The preamplifier consists of 2 units: the main control unit and the power supply unit. 

Each unit comes in its own original wooden crate with all the original packaging materials and accessories. (manual, power cord and interconnect cable to go between the control unit and the power supply unit)

For estimation of shipping costs: Please use 3-day Fedex Air as suggested by the manufacturer and include shipping insurance. Both crates are identical in size and the dimensions of each crate is provided above. Shipping weight for the control unit crate is 35 lbs and for the power supply unit crate 39 lbs.

Please add only 1.4% to the price if you would like to pay via PayPal in light of mutual convenience.

Thank you for your interest.


Description from Official Website:

Model L2 Reference represents top of the line in 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. Unique topology and application of the most advanced technological resources and processes bring the L2 near the threshold of excellence in sound reproduction. A main distinction of the L2 from any other comparable type of preamplifiers is its almost inaudible sonic signature. When connected to an appropriate type of power amplifiers, and especially LAMM amplifiers, it assures the extraordinary transparency of perceived sound and recreation of a three-dimensional soundstage in the home, recording studio, etc., without boundaries and limitations.

The L2 features a topology that brings out the most natural sound performance in the audio path, as well as graceful and sophisticated design. Its unique circuitry utilizing specially selected super-linear high voltage MOS-FET transistors ensures a class A operation from input to output, with no overall feedback at any stage. All stages, including high current output buffers, are single-ended. A unique electronic protection circuit enables manual muting of the outputs until the preamplifier has stabilized after a turn-on; it also enables functioning of the preamplifier in a "muting" mode during operation and automatic switching to muting in case the AC line voltage drops or is interrupted. Other features include 3 inputs; 1 tape loop; output signal phase switch; balanced and single-ended outputs; and built-in remote on/off for LAMM power amplifiers.

The L2 has a separate power supply that utilizes a choke contained filter, vacuum tube rectifier and voltage regulator.

Special care was taken in designing a high voltage (+350V) high speed vacuum tube voltage regulator. Using this voltage regulator, in conjunction with other technical aspects, enables the reproduction of tiniest nuances and three-dimensional subtleties in the music palette (provided that such details had not been lost in a recording process). A somewhat unusual combination of high voltage vacuum tube power supply and superlinear high voltage MOS-FETs allows to attain an enormously large output swing while retaining practically constant harmonic contents of the signal with an absolute dominance of the second harmonic.

In designing the L2 special attention was directed toward optimization of the output impedance of the preamplifier with an aim of attaining practically full independence of the output impedance from frequency, as well as to allow the preamplifier to drive (without audible sonic degradation) significant capacitive loads created by many modern interconnect cables.

Each preamplifier is carefully hand-crafted with matched components of the highest quality, some of which include military graded low noise DALE metal film resistors; unique TKD stepped potentiometers (41 detents); PRC wire wound resistors; ELECTROCUBE and ROEDERSTEIN film capacitors; high frequency switching grade CORNELL DUBILIER electrolytic capacitors; specially selected long life vacuum tubes; high quality heavy duty gold-plated RCA connectors; and gold-plated NEUTRIC XLR connectors. The preamplifier power supply features a custom-designed super-low noise toroidal power transformer. AC voltage is filtered by special RFI power line filter.

Summing up the above, we take the liberty in stating that we have been able to create a preamplifier with practically no sonic signature, of course, taking into consideration the fundamental limitations inherent in reproduction of live music by electronic means.

The L2 works on all world AC line voltages (100/120/220/230/240V).
