September 2016

11- we are happy to announce that a modification of our long-running L2 Reference preamp -- the L2.1 Reference -- is going to become commercially available in October'2016.

The L2.1 Reference employs a pure class A operation from input to ouput, with no overall feedback at any stage; all stages, including high current output buffers, are single-ended. Also featured are specially selected high voltage super linear MOS-FETs in the signal path and TKD stepped potentiometers for volume control – the best available on today’s market.

The preamplifier’s audibly neutral power supply features a choke contained filter, a full-wave vacuum tube rectifier and vacuum tube voltage regulator which allow to virtually eliminate the hum and buzz and, ultimately, to ensure the authenticity of the essence of sound throughout the entire dynamic range without any coloration.  Other features include 3 inputs; one tape/home theater processor loop; output signal phase switch; balanced and single-ended outputs; protection circuitry designed to enable manual muting of the output signal; and built-in remote on/off for Lamm power amplifiers.

The main distinction of the L2.1 Reference from any other comparable type of preamplifiers is its almost inaudible sonic signature.  When connected to an appropriate type of power amplifiers, especially LAMM power 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. 

In a nutshell, the L2.1 Reference includes the following upgrades and modifications as compared to the L2 Reference:

  • increased immunity to unwanted radio frequency interferences propagated via both radiation and conduction over signal lines & AC power systems
  • certain modifications in protection and time delay circuitries
  • improved signal/noise ratio
  • replacement of a number of critical components with newly available types of better quality [in particular, replacement of electrolytic capacitors in the tube voltage regulation section with newly developed high density polypropylene capacitors of comparable size and value(!)]
  • utilization of a technologically new type of pc-boards of superior quality, with gold-plated traces and thru-holes.

Each preamplifier is carefully crafted with the finest materials and top quality parts like military-grade DALE/VISHAY metal-film resistors, RCD wire-wound resistors, TKD 41-step volume control potentiometers of the highest quality available on today’s market, BOURNS multi-turn potentiometers, VISHAY electrolytic capacitors, ELECTROCUBE, EPCOS and RIFA/KEMET film capacitors; HAMMOND chokes, god-plated NEUTRIC connectors, and military-grade low-noise long-life vacuum tubes.

The L2.1 Reference features a custom-designed super-low noise power transformer.

           (November 2015, issue 257):

  • ML2.2 amplifier
  • These 18W single-ended triode monoblocks are so magical (with a load-appropriate loudspeaker) that they made me question the paradigm of high-powered solid-state amplification. The directness of expression, the palpability of images, and the purity of timbres are simply sensational through the ML2.2. These amplifiers make it sound as though the musicians are speaking through time and space directly to you. It's an uncanny quality that must be experienced to be appreciated. The ML2.2s achieve this level of sonics not through a euphonic or tubey sound, but by conveying the virtues of SET amplification with SET colorations. With the right loudspeaker (a big caveat) the ML2.2s don't sound like tubes, SET, solid-state, or any other technology. Rather, they sound like music

  • ML3 Signature amplifier

    This four-chassis, 32Wpc, $140k SET may strike some of you as the Poster Child for Audiophile Excess, but theLamm ML3 Signature amplifier takes the definition of the absolute sound and turns it on its head. For 30 years, the illusion of live unamplified instruments in space has been what we've been aiming for. Now with this Lamm attack on the state of the art we can (almost) throw away the word "illusion". The Lamm ML3 Signature approaches what we all seek in the reproduction of music -- the actual sound of live instruments in space -- by reducing or eliminating two of the major sonic colorations that reviewers harp on: electronic haze and midbass overhang. The cost of entry is unquestionably high, but the performance is even higher.

  • LL2.1 preamplifier

    A direct replacement for the LL2, LAMM's long-standing, entry-level, tube linestage preamp is an all-tube design, featuring both tube rectification (6X4) and amplification. Harmonic colors are vivid and saturated to a level approaching the real thing with admirable fidelity. The LL2.1's primary concession is in the area of soundstage transparency. It also requires tube-rolling to achieve optimal performance at the frequency extremes. The LL2.1 is extremely easy to live with and integrate into an existing system. According to DO, when outfitted with the right tube complement, it captures 80% of cost-no-object performance for a fraction of the price.

  • LL1.1 preamplifier

    This four-chassis, dual-mono preamplifier is that rare breed that strikes a near-perfect balance between transient attack and instrumental body, and does so from top to bottom in both frequency response and amplitude. Its ability to deliver speed plus sustain at all dynamic levels is extraordinary. The result is near-perfect timbre and, if the rest of your system is up to it, nearly ideal imaging.

  • LP2.1 phono preamplifier

    A significant upgrade of the LP2, which was Lamm's entry-level phonostage for many years. In addition to a parts refresh, the tube complement has been changed to the Russian 6C3P and 6C45P-E triodes. Both moving-magnet and moving-coil inputs are accommodated. The emphasis is entirely on signal purity. An exceedingly low noise floor is a major plus, allowing the music to swell up from a velvety black background with no perceptible hash or grain. The presentation is detailed but not overly so. The vibrancy and urgency of human voice are reproduced exceedingly well. Tonal colors are beautifully rendered but without excessive tube warmth. The tonal balance is very much on the neutral side of reality. In sum, the LP2.1 is a perfect marriage of traditional solid-state strengths such as bass power and low-noise with the glorious harmonic textures and the dynamic convictiton of tubes.
