MBL N51 MKII Integrated Amplifier

The MBL N51 MKII is the flagship integrated amplifier of MBL's Noble Line - a refreshed 2026 version of the N51 that adds MBL's LASA 2.0 (Linear Analogue Switching Amplifier) technology, Soft Clipping for distortion-free playback even at very high volumes, and MBL SmartLink networked control. 2 x 380 watts into 4 ohms with 25 amp peak output current means the N51 MKII can drive any of MBL's Radialstrahler speakers (116 F, 120 MKII, 126 MKII) with authority in a single-chassis, integrated form factor.

Up to 7 source inputs (balanced XLR + RCA + optional phono module). Analogue potentiometer with precision stepper motor volume control - the same volume topology used in MBL's Reference Line preamps. 5-inch TFT high-resolution color display shows source, level, and system status. Backlit multi-function remote with elegant rotary volume dial. Individual inputs can be enabled/disabled for quicker source selection.

Differential amplifier inputs for optimum common-mode rejection. 100% Made in Germany at MBL's Berlin factory, backed by a 5-year unconditional warranty. Priced at $23,800 in current MBL pricing. Pairs naturally with any MBL Radialstrahler speaker - or with the N31 CD-DAC for a complete Noble Line system.
