 LAMM
 INDUSTRIES
Lamm Industries is an American company that has been in business since October, 1993 producing a limited line of very high-quality products known as some of the best tube and hybrid gear in the world.

 

 
 Sound
The company sound is natural, musical and consistently excellent across the entire line of products.

There is something called the 'Lamm Magic', which, when added to a system, helps imbue that system with a much needed dose of musicality.

Anyone who has heard the Wilson Watt/Puppy 7 or Pipedreams or Kharma or so many other speakers being driven by amp after amp, sounding cold, harsh, fatiguing... and then heard these same speakers with Lamm amplifiers - knows that it is not the speakers that sounded so awful - or perhaps it is that the Lamm amps sounded so good.

 

 
 Technology
 

 

 

 

 

 

 
 Portfolio
Lamm makes two hybrid solid-state/vacuum tube amps, one 6C33C tube amp and one GM-70-based amp, three preamplifiers (one tube, one hybrid), and a tube phono preamplifier.

Every component in the Lamm line is best-of-class ... an amazing feat for any line of electronics. One of the most highly awarded lines in Hi-Fi.

 
 History
All of the products at Lamm Industries are designed by Lamm's head-engineer and president Vladimir Lamm. Vladimir Lamm (changed from Vladimir Shushurin when he became a citizen) emigrated to the U.S. from Russia. Vladimir has a M.S. degree in Electronics and Solid-State Physics and worked many years in Russia on his models of the “human hearing mechanism". More...
