LAMM LP1 Signature Tube Phono Preamplifier

The dual monaural phono preamplifier model LP1 Signature
is the ultimate statement of perfection in High End audio.
Just like the ML3 Signature and LL1 Signature, the LP1 Signature is one of the best creations of its designer’s professional career.

The LP1 Signature has been designed to complement the ML3 amplifier and the LL1 preamplifier.  It completes the SignatureSeries triad and, in combination with the other two Signature components, represents a “match made in heaven”.  However, the LP1 Signature will perform its magic in any system provided it is of sufficient quality.

The experience of listening to the LP1 is a unique one.  It is, at once, intimate and expansive—as if being transported to a space that belongs to just the listener and the music as they merge with one another. With no electrical artifice to impede communication, a greater understanding of the music is immediately possible. Thus enabled, the listener can enjoy each and every musical element locked in the LP’s grooves with newfound depth, profundity and insight.

The LP1 Signature features a topology that brings out the most natural sound performance in the audio path.  The main distinction of the LP1 Signature from any other comparable type of preamplifiers is its almost 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.
The LP1 Signature is a vacuum tube preamplifier that employs a high current pure class A operation from input to output.  No loop feedback is employed.  Other features include:

• Audibly neutral power supplies (one for each channel) featuring full-wave vacuum rectifiers, choke contained filters, vacuum tube high-voltage regulators, and solid-state low-voltage analogue non-switching regulators used as the heater supplies
• Three separate inputs for MM and MC (two inputs) cartridges
• All amplification stages utilize high transconductance super low noise high-current vacuum triodes
• Very accurate RIAA EQ network

Each preamplifier is carefully handcrafted of the finest materials and hand selected top quality parts like military-grade DALE metal-film resistors, RCD wire-wound resistors, BOURNS multi-turn potentiometers; ELECTROCUBE, CORNELL DUBILIER and ROEDERSTEIN film capacitors; high frequency switching grade CORNELL DUBILIER electrolytic capacitors; HAMMOND chokes; gold-plated NEUTRIC connectors; and military-grade low-noise long-life vacuum tubes.

A custom-designed massive damping panel installed in the preamplifier unit significantly reduces all types of mechanical vibrations which, in turn, leads to a more extended, coherent and natural bass reproduction.
The LP1 Signature features a custom-designed super-low noise power transformer.
