Product Description

The Lamm LP2.1 Deluxe Phono Preamplifier (released in spring of 2014) is one of the finest tube phono preamplifiers in the world in this price range; it’s based on the Design of the Lamm LP1 Signature model, which retails for $34k. The LP2.1 now uses the same tubes as the Signature but is contained on a single enclosure, whereas the Signature has two additional enclosures to house the power supply for each channel. The LP2.1 Deluxe is the great value, not inexpensive, but absolutely world-class and along with the Lamm LL2.1 linestage preamplifier, the LP2.1 represents a tremendous value.

This is a dual-mono vacuum tube phono preamplifier with two electrically and mechanically separated channels. It features a topology that brings out the most natural sound performance in the audio path, as well as graceful and sophisticated design, which operates in a pure class A mode from input to output. High-current drive capability, in combination with unique single-ended class A circuitry, enables the preamplifier to drive any cable and any reasonable real-world load, while maintaining its practically inaudible sonic signature. When connected to the appropriate type of electronics, and especially LAMM amplifiers and preamplifiers, 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. All amplification stages utilize high transconductance very low noise high-current vacuum triodes. No loop feedback is employed.

The LP2.1 features a very accurate passive RIAA EQ network. The preamplifier’s audibly neutral power supply features a full-wave vacuum rectifier which, together with a choke-containing filter, helps reduce the hum and buzz to almost negligible levels and, in the end, ensures the verity of dynamic range without coloration. The solid-state analog voltage regulator is used as a heater supply. Other features include two sets of inputs for each channel and gain/selector switches for MM and MC cartridges.

Each phono preamplifier is carefully crafted with the hand-selected components of the highest quality, some of which include military graded low noise DALE metal film resistors; 1% tolerance RCD wire-wound resistors; ELECTROCUBE and VISHAY/ROEDERSTEIN film capacitors; high frequency switching grade CORNELL DUBILIER electrolytic capacitors; FISCHER “Camac” connectors; specially selected military-graded low-noise long-life vacuum tubes; and a custom-designed super low noise power transformer.

 

Michael Fremer of Analog Planet said of the original LP2 model and now with the LP2.1 the unit has been brought a big step forward toward the Signature model. Note that there were substantial changes in the LP2.1 circuit, after the LP2, including new types of tubes.

“Subtle string textures, reeds, and female voices were positively thrilling, and the size and weight of the entire picture—especially stage depth extending well behind and in front of the speakers—was particularly impressive. Add that to snap-you-back-in-your-seat dynamics and authoritative decay, and the Lamm became one of a handful of the finest phono sections I’ve ever heard.”
