Reviews & Awards

The sound is great -- sweet, refined, full of dynamics - fabulous on grand piano.
Tony Faulkner, Greenroom Productions, UK owner of HV-3D and M-2B preamplifiers

Guitar, violin, flutes and other instruments in stereo array with Schoeps sound so pure, sweet and spacey. I especially love the tube preamp (M-2b) with the transformer engaged
sometimes. Really a happy day and hopefully many happy days yet to come... It was preceded by two months of communication with Millennia and John La Grou - and he was so kind to me, answering all possible questions
and being extremely helpful.

This is an outstanding mic preamp. I’ve never heard our mics sound this clean on piano. We’ve been using our [46 channels of] Millennia preamps on everything... 
Jack Renner, President, Telarc Records International

A couple of experienced recording engineers here in DC thought my combination of Schoeps m222b tube mic and M-2b preamp was the greatest front end they had ever heard.
Steve Cormier

“The M-2b is an audio masterpiece. Tube technology at it’s finest- which in my book means audio technology at it’s finest! Our first choice for vocals and piano. If we owned
more channels, the M-2b would probably be first-choice on everything until we ran out of them! Like everything from John La Grou’s workbench, the M-2b is built like a fine watch. A pleasure to hear, see, and touch.”
Randy Ezratty, Effanel Music, Inc.

Still mesmerized each time we listen to this thing - the more we do with it, the more harmonics jump outta this thing! And it isn’t even broken IN yet! It’s just absolute insanity.
Compliments to the chef.
Ira Segall
