MP-M201 MkII is specifically designed for complex dual-gain speaker systems and solves typical problems found in such systems, including external active crossovers and special bass amplification. When you think about the uncompromising approach we take to each project, you will quickly understand why this amplifier took years of painstaking and complex development to create something truly impressive.
The SM-011 builds on the success of the SIA-025. You get more of everything, more silence, higher resolution, more power, and better dynamics. The amplifiers are equipped with a special 1.4 kVA UI transformer with losses of <2%, a battery of 240,000 UF capacitors, are fully balanced from input to output and, as always, have zero global negative feedback.
