It's pretty cool stuff. Manley purchased the name some years ago. No original Langlavine circuit designs are actually used in the gear. Instead it's all solid state versions of the Manly catalogue. The Electro-Optical-Leveling-Amplifier is quite nice. The build quality is excellent, and pretty consistant from unit to unit. You don't get those awesome tube drivers from the Manley units, but all in all they sound great and are a really good buy for the $.Plus Evana rocks.
