MSB M205 Mono Amplifier
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.
MSB M205 MONO AMPLIFIER
MSB Technology, of Silicon Valley, California, says that the MSB M205 perfectly complements their DACs’ “ultra high dynamic range, with optimized architecture in the critical areas of audio performance, power supplies, and ultra low-noise design”.
The MSB M205 Mono Amplifier features fully modular cores, matched impedance input stages and a billet CNC cut chassis.
