The LL2 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.

LAMM LL2.1 Line Level Vacuum Tube Preamplifier. 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; new knobs

As the next generation of the original LL2 LAMM vacuum tube preamplifiers, a main distinction of the LL2.1 is its almost inaudible sonic signature. When connected to the right LAMM amplifiers, it recreates a three-dimensional soundstage in the comfort of your own home.

2005年9月25日 · Lamm Industries, of Brooklyn, New York, makes two different line-level preamplifiers. Their flagship is the L2 Reference, a $14,390, two-box affair that uses vacuum tubes for rectification and regulation, and transistors for gain, and which I've heard only in unfamiliar systems: trade shows and the like.

The LL2.1's input impedance is specified as 50k ohms and its output 250 ohms, the latter suggesting good compatibility with a variety of power amplifiers. Lamm's recent introduction of the LL2.1 brought with it the opportunity for Stereophile to listen once again to the company's analog stalwart, the LP2 Deluxe phono preamplifier, which Mikey ...

Lamm Industries LL2.1 Tube Dual Mono Preamp. Line level vacuum tube preamplifier with 3 inputs, 1 tape/HT processor loop, 2 sets of single-ended outputs. Attenuation for gain reduction by 15 dB.

Taken as such, the Lamm LL2 is not for the audio enthusiast who demands home-theater–like luxury from his music system, or who wants at his fingertips various adjustments—phase inversion, mono blending, channel reversal, even bass and treble lift.

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 LL2.1 Deluxe didn’t have the over-the-top, dripping-wet richness and presence of some tube preamps, or the largest-scale dynamic swings of the costliest solid-state preamps, but it definitely sounded richer and grander than most solid-state designs, and dynamic enough to make recordings sound all the more real and alive.
