About the LP1 Signature
The Lamm LP1 Signature is a premium single-ended vacuum tube phono preamplifier designed for ultimate audio fidelity. It employs high-current pure class A operation from input to output with no loop feedback, utilizing high transconductance, super low-noise, high-current vacuum triodes in all amplification stages. It features three separate inputs: two for moving-coil (MC) cartridges and one for moving-magnet (MM), each MC input with a dedicated step-up transformer. The audibly neutral power supplies (one per channel) include full-wave vacuum rectifiers, choke-contained filters, vacuum tube high-voltage regulators, and solid-state low-voltage analog non-switching regulators for heaters. A custom-designed massive damping panel reduces mechanical vibrations for extended, coherent bass. Handcrafted with military-grade components like DALE resistors, ELECTROCUBE film capacitors, HAMMOND chokes, and gold-plated NEUTRIC connectors. It is listed under discontinued products on the manufacturer's site, with the company undergoing reorganization but planning to resume operations in early 2025.
