Not Square!
As you’ve probably noticed, the MSB M202 Monoblocks are round! This design allows us to keep the signal paths as short as possible for the best possible performance.
Truly Balanced Architecture
Both the inputs and the outputs of this Amplifier are completely Balanced. There is no funny business going on here! The M-202 also offers a single-ended input that is treated separately from the balanced input. A simple switch located near the input jacks allows you to switch the Amplifier between Single-Ended operation, Balanced (high gain, + 6dB) and Balanced (low gain).
Control Features
Based on customer requests, the MSB M202 Monoblocks has both a total power on / off and standby mode all selected by the lighted toggle on top and via a remote jack on the back. It also has a high/low Bias switch allowing the Amplifier to run in a cooler mode for hot environments, and hot as a pistol for the very best sound possible, even at the expense of a high air conditioning bill.
The heart of the MSB M202 Monoblocks is our MSB designed current mirrors. This approach is expensive but allows amazing accuracy. With such great accuracy we can even operate with zero feedback, greatly improving our phase response. Negative feedback is a trick used by most amp designers to improve linearity but its cost is in degraded phase performance. Our use of zero feedback is significant breakthrough and indicates the care taken in our design.
Other improvements include the use of toroidal transformers keep noise levels low as does the dense packaging. High quality connectors are used on the back of the unit with both balanced and single ended inputs.
