Power amplifiers mono — Lamm Industries M2.2

The M2.2 is the most powerful monoblock hybrid amplifier from Lamm Industries, demonstrating unique transparency and soundstage volume, with an output stage built on high-speed MOSFET field-effect transistors. The M2.2 brings Lamm's most storied engineering to a serious, high-transparency monoblock format.

Key specs that matter

Input impedance is a substantial 41,000 ohms on both balanced and single-ended connections. Output impedance is a remarkably low 0.098 ohms single-ended. Output power is 220W into 8 ohms, rising to 440W into 4 ohms. Frequency response spans an exceptional 4Hz to 155,000Hz within plus-or-minus 3dB. Damping factor is 89. At 21.0 x 43.2 x 49.5cm and 31kg, the M2.2 represents Lamm's most powerful current monoblock hybrid engineering.

Sound and use context

Expect unique transparency and soundstage volume reflecting the exceptional 155kHz upper bandwidth combined with the remarkably low 0.098-ohm output impedance, with the high-speed MOSFET output stage delivering the control and clarity Lamm's hybrid topology is broadly celebrated for.

Pairing

As a monoblock, two units are needed for a stereo pair, and the remarkably low 0.098-ohm output impedance handles demanding loudspeaker loads with genuine ease.
