N21 프리앰프의 경우는 전면에 대형 5인치 LCD 디스플레이로 프리앰프가 전달해야할 다양한 정보를 제공함과 동시에 세련된 외관을 보여주고 있다. 또한, 2개의 밸런스 입력과 5개의 언밸런스 입력으로 아날로그 입력을 구성하고, 옵션으로 밸런스 입력단이나 포노단을 추가할 수 있다고 한다. 프리앰프가 가져야할 덕복인 유니티 게인 기술을 통해 넓은 다이내믹 레인지와 동시에 초저노이즈와 퓨어한 사운드를 제공하도록 제작되었다.
한편 매칭된 N21 파워 앰프는 파워앰프가 해야할 히트싱크를 전면에 디자인적인 포인트로 내세워 제작하였다. 심플한 출력단과 높은 효율을 가진 클래스 D로 소형 히트싱크를 가지고 있으며, 트랜스포머는 내부적으로 노이즈를 차단하기 위해 차폐되었다. 또 하나의 중요 기술로 'LASA(Linear Analog Switching Amplifier) 2.0' 기술을 사용하였는데, 클래스D 증폭에서 나오는 고역에서 나오는 임피던스 변화에 따라 발생하는 것을 없애기 위해 LASA 2.0 기술 사용하였고, 임피던스 매칭과 관계없이 일정한 주파수가 나오도록 했다. N21 파워앰프는 4Ω 기준 380W이며, 높은 댐핑 팩터를 가지고 있어 왠만한 스피커도 구동할 수 있다.
럭셔리 하이엔드 오디오의 선두주자 독일 'MBL'의 Noble Line N11 Pre, N21 PowerAmp 는 2018 멜론 서울국제오디오쇼 샘에너지 부스에서 만나볼 수 있다.

MBL Noble Line N21 Power Amplifier |
LASA 2.0 amplifier – MBL-developed technology that combines the advantages of |
different amplifier concepts. The resultant amplifier is perfectly suited to drive complex |
loads such as loudspeakers, ensuring that the frequency response remains stable even at |
varying loads and has a homogeneous tonal balance throughout frequency range |
Symmetrical layout for better common mode rejection |
Soft Clipping – even at very high volumes the amplifier goes gently into clipping mode, |
never sounding aggressive or distorted |
Power supply is made by a massive analog toroidal transformer with protective shield |
technology in its MU-metal enclosure |
380 watts (4 Ω) power with 28 Amp peak output current, values that ensure a sovereign |
and unconstrained performance even at higher volume levels |
Rectifier with low recovery losses |
High-quality, vibration-damped full copper loudspeaker connections (binding posts) by |
the German manufacturer WBT |
