Millennia M-2B – No Longer Available

Transformerless stereo vacuum tube microphone preamplifier

Product Description

Unlike any tube pre you've heard before, the Millennia M-2B features a unique transformerless design, giving it a gentle voice that stands out in the preamp crowd. It's a departure from the precise and pure Millennia HV-3 solid-state series, and, at the same time, it offers something different from the color-stacked, big-mojo personality that comes to mind when you think "tube pre." The M-2B is subtle. It's detailed. It's like a splash of tube character, just enough to add that "something" you want from a tube pre, but not so much as to overbear or take over the show. Think three-dimensional tube texture without a loss of detail. That's the Millennia M-2B.


  • Subtle, gentle tube texture
  • Millennia gear is made for detail

Subtle, gentle tube texture
The Millennia M-2B proves that tube character can exist on a spectrum. It doesn't have to be an either/or of full-on, in-your face color on one end with ultra-clean amplification on the other. The M-2B occupies somewhere in between, making it a standout for engineers wanting something special, something different. Thanks to the M-2B's unique transformerless design, you can get a splash of tube texture and musicality, a bit of a glow, without losing the detail you want, too. Easy does it.

Millennia gear is made for detail
Founder and chief designer John LaGrou takes the same approach to his exceptional audio gear as he does to the wine he cultivates in the California countryside. Detail matters, it's everything. Whether in a vintage of wine or your multi-track mix, taken together, those details can make a major difference in the end result. Millennia equipment celebrates those fine, subtle points, bringing you gear that's built with uncompromising quality to deliver purity in music.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
