Jaguar is an authorized retailer for all Lamm Industries gear. These products, designed by Vladimir Lamm and built at the Lamm New York city headquarters, are legendary, for amazing sound...there's nothing else like it.
Lamm produces three models of linestage preamplifiers that fit in distinct budget categories. At each level, these are some of the finest linestage preamps in the world.
- LL2.1 Deluxe - A great value, not inexpensive, but most definitely world-class. This is the best choice for most audiophiles.
- L2.1 Reference - This model provides reference-level performance. This model uses a more intensive power supply, in a separate chassis.
- LL1.1 Signature - The Signature is the ultimate Lamm preamplifier and uses four chassis, with a separate control and power supply unit for each channel.
The LL2.1 is a direct replacement for the LL2 preamplifier. The LL2.1 features the following upgrades and modifications as compared to the LL2:
addition of a built-in remote on/off for LAMM amplifiers
introduction of the attenuation for gain reduction by 15 dB
some new parts
slight changes in schematic diagram
Model LL2.1 is the next generation of the original LL2 which was the first in the line of LAMM vacuum tube preamplifiers. Unique topology and application of the most advanced technological resources and processes bring the LL2.1 very close to the threshold of excellence in sound reproduction. A main distinction of the LL2.1 from any other comparable type of preamplifiers is its almost inaudible sonic signature. When connected to an appropriate type of power amplifiers, especially LAMM amplifiers, it assures the recreation of a three-dimensional soundstage without boundaries and limitations.
The LL2.1 features a topology that brings out the most natural sound performance in the audio path, as well as graceful and sophisticated design. It employs a pure class A operation from input to output; all stages are single-ended. The preamplifier's audibly neutral power supply features a full-wave vacuum rectifier. This rectifier, together with a choke-containing filter, allows to practically get rid of the hum and buzz and, in the end, to ensure the verity of dynamic range without coloration. Other features include 3 inputs; 1 tape loop; 2 sets of outputs; front panel muting switch; attenuator for gain reduction by 15 dB; built-in remote on/off for LAMM power amplifiers; protection circuitry coupled with automatic mute at turn on/off.
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; NOBLE potentiometers; ELECTROCUBE and ROEDERSTEIN film capacitors; high frequency switching grade CORNELL DUBILIER electrolytic capacitors; and specially selected long life vacuum tubes. The LL2.1 features a custom-designed power transformer.
The LL2.1 is available in two versions: standard and deluxe, both of which utilize identical chassis, PC-board and parts. In the Deluxe version, the power supply energy storage is approximately twice that of the standard version (four identical light-blue capacitors next the choke; only two of these are installed in regular version -- see first detail image insert).
Also, all film capacitors in critical paths are paralleled by polystyrene capacitors of the highest available quality (yellow capacitors on two images -- right and below). The LL2.1 works on all world AC line voltages.
"the Lamm presented music so cohesively and convincingly, with so exceptionally natural and thoroughly engaging sound, that I easily lost myself in the music, largely ignoring the nitpicky things that so worry audiophiles -- and especially reviewers. Not many components can do this for me. When I did dissect the LL2.1 Deluxe’s sound, I found things here and there that other preamps do better -- but that missed the point of what the LL2.1 Deluxe did so well: present a realistic and thoroughly engaging sound that was tough to stop listening to."
