MSB TECHNOLOGY M205 MONO AMPLIFIER LAUNCHED

After they launched the MSB S202 Stereo Amplifier, MSB Technology said that they had many requests for an improved mono amplifier in the same compact chassis.

The MSB M205 refines the S202’s performance with an upgraded input stage and a doubling of the power supply transformers and capacitors.
