Stereo Power Amplifier MBL N21 MKII

The powerful synergy of the N21 MKII Stereo Power Amplifier begins with their common LASA 2.0 circuit design, exclusively developed by MBL and found in every Noble Line power amplifier. LASA delivers unbridled sound reproduction—sparkling, palpable, and completely uncolored by any audible influence from the technology within.

The signal routing concept for each channel is clever without being difficult, ensuring a perfect transfer thanks to a technique known as common-mode rejection—a factor that embodies the close relationship with the larger brother, the mono N15. Match an N11 preamplifier with an N21 MKII stereo amplifier for a combination that consistently delivers a musical experience that transcends the aural boundary of magnificent.

The new MKII generation introduces a completely redesigned amplifier module that further refines the performance of the N21. With reduced power consumption at idle, improved Total Harmonic Distortion (THD), enhanced Signal-to-Noise Ratio (SNR), and improved channel separation, the N21 MKII achieves even greater precision, efficiency, and transparency while preserving the musicality that defines MBL's Noble Line.

State-of-the-art technology – LASA 2.0

The second generation LASA amplifier technology combines the finest qualities of traditional Class A and Class AB amplifiers with the benefits of “switching amplifiers”. LASA 2.0 delivers the homogeneous THD curve of Class A operation, a stable frequency response even with multiform loudspeaker loads of Class A / B circuits, and the high efficiency and low heat radiation of a switching output amplifier. The result is a power amplifier circuit that remains completely stable even under complex, demanding loudspeaker loads, maintaining absolute authority even at high volumes.
