Founded in October 1993, LAMM INDUSTRIES, INC. has gained a world-wide reputation for designing high-end audio products of astonishing sonic performance. From our LL2.1 linestage preamplifier to the ML3 Signature monoblock amplifiers, the performance of LAMM products is setting standards for audiophiles the world over.
LAMM employs tube and solid-state technology, along with innovative engineering, to create products that many have heralded as reference class. All our products are designed to deliver not only the best performance at their respective price points, but at any price. All products are designed and manufactured in the USA and are covered by three U.S. Patents. Using optimal parts quality with meticulous attention to detail and the finest craftsmanship, LAMM INDUSTRIES proudly creates what we believe to be the finest audio components on the market today. Although not inexpensive, LAMM products represent an investment in long-term musical satisfaction.
Owned by some of the finest audio critics and journalists in the world, enjoyed by countless audiophiles in many countries, LAMM products deliver breakthrough performance and uncompromising sonic quality.
LAMM INDUSTRIES, INC. has been conceived, founded and run by its president and Director of Engineering, Vladimir Lamm. As in the case of a “theater of one actor” where the actor’s character determines the nature of plays and their performance, LAMM is an embodiment of Vladimir’s extensive experience, unbending motivation, and love of music. He is involved in the entire process of product development, from concept to implementation into production, and he personally stands behind each product.
The company is operated by a very stringent set of standards. No detail is too small or unimportant; what’s hidden from the eye is just as important as what’s visible. Strict quality control is maintained throughout the entire production process. All key elements are carefully selected, tested and matched (where necessary). Every module and assembled PCB is test-bench tested, followed by an 8-10-hour burn-in period. The product is then assembled and tested, followed by a 72-hour burn-in period. The burned-in units are then retested and re-measured. The “pre-burn-in” and “post-burn-in” measurement results are recorded in a production report maintained for each piece of equipment. LAMM products operate on all world AC voltages without elaborate modification.
