The M-3 is a mono power amplifier from Soulnote, built with an extraordinarily wide bandwidth and exceptional power efficiency. The M-3 brings Soulnote's considered engineering to dedicated monoblock power amplification.
Key specs that matter
Input sensitivity is 2,000mV, with input impedance at 25k ohms balanced. Output power is 160W into 4 ohms. Gain is 22dBu. Frequency response spans an extraordinary 2Hz to 200,000Hz within plus-or-minus 3dB - a remarkable bandwidth. Total harmonic distortion plus noise is 0.1% with full global feedback, and maximum power consumption at a modest 110W - a remarkably efficient figure relative to the 160W output. At 340 x 257 x 512mm and 31kg, the M-3 represents a substantial monoblock commitment.
Sound and use context
Expect clean, efficient power delivery reflecting the extraordinarily wide 2Hz-200kHz bandwidth combined with the remarkable power efficiency, consistent with Soulnote's broader purist Japanese engineering philosophy.
Pairing
Soulnote's own D-1N or D-2 DACs and E-2 phono stage share the brand's coherent engineering philosophy, forming natural companion components.
Alternatives
Soulnote's broader amplifier catalogue offers alternatives for buyers wanting a different output level.
