The MB-185 Series II Signature monoblock delivers superior performance at an affordable price. It offers the same technological improvements and cosmetic refurbishment as its bigger brother, the MB 450 Series II, although in this case using six 6550C tubes and a more compact output transformer to make 220 watts per channel.

The extensive updates to the Series II amplifier include a revised power supply, SmartTube technology with automatic bias adjustment and fault sensing, and upgraded electronic components. The result is an amplifier with improved dynamics as well as superior speed and transparency at the top end. With its extraordinary agility, the MB-185 Series II is ideally suited for use with planar or electrostatic speakers as well as dynamic speakers with 10-inch or smaller drivers.
