LP1 SIGNATURE 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 LL1.1 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 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

This is one area where the LP1 eclipsed other Lamm electronics — the ability to sound big, bold and forceful, while never abandoning its sonic roots. With recordings that bring it out, the LP1 knocks down the walls of the listening room, putting you amidst the band or orchestra. Dynamics were extreme, the whole presentation showing off the full capabilities of my analog rig — things I had never quite heard it do, in fact.
Along with this massive sense of scale was copious air in the mids and treble. The LP1 could impart an authority even as voices and especially strings trailed off like wisps of smoke in a light wind.
It also dug into recordings, focusing their energy within the listening space, and there was no better illustration of this than mono jazz.
It distinguishes records from each other, unearthing low-end weight and detail, fine points of the recording’s construction and venue, while sounding fluid and natural — like analog, but just a more varied, more complex, and more satisfying version of it.
There is just too much to be said about this phono stage — its presence and power, its dynamic athleticism, its focus and transparency, its speed, its intrinsic naturalness. It can play big or small, revealing the character of recordings with rare ability, while never parsing the music into mere sonic elements.

What I heard after the lengthy burn-in was no ordinary soundstage. A massive, unshakable foundation was laid out in front of me. The images of the instruments were precisely positioned with such density and weight the presentation had the aspect of a large piece of aural sculpture. The effect was immensely impressive in audio terms—and immensely satisfying musically.
The LP1 Sig strikes a nice balance, providing a firm foundation while allowing the images to dance. And it always projects a musical, flowing line.

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 natural, lush, dark and evolving pace is remarkably outlined. Overtones, micro dynamics and non-usual tonality embarks at a fullest scale. Music being reproduced was special and most involving. I was trapped with the flamboyant and exotic presentation.
Micro dynamics, translated into the sum of smallest nuances of micro delays, reverberations and focus points comes vividly painted only at this degree of analog high-tech. This is what makes the vinyl listening utmost involving and what creates an emotional packed listening journey of a higher degree.
Lamm LP-1 Signature phono preamplifier shines with the translucent ability in shifting from the pianissimo to forte fortissimo in exact same way! Bold in its nature, fast as it gets, retrieves the minute shifts of both micro and macro dynamics expertly. Peaks and attacks of the sudden dynamic changes are being portrayed with the sense of authority and rich tonality. And this is not obvious only with classical music, but extended all over the musical genres.
Lamm LP1 Signature phono preamplifier brings me into the same mood I’ve encountered when owning the LL2.1 preamplifier. Its a contemplating state of mind, music perpetuum mobile and similar projection of impressive sound dispersion and refined, unaltered series of individual notes I’ve encounter way back. But this time with Lp-1 Signature on even more immersive and impressive level.
