M5si 

The M5si is a real high end amplifier. At 150wpc, with high current delivery, it will drive virtually any loudspeaker easily.

Internally the M5si is configured as two independent monoblocs with a separate preamp, but all mounted on one pcb. Its technical performance is about equal to the M6si. 

The M5si In Brief

• 150wpc
• Excellent technical performance
• Preamp output
• Unconditional stability, will drive any loudspeaker
• Wide range of useful inputs including asynchronous USB and MM phono
• Excellent hunky build quality
