The NHB-108 was the first power amplifier designed and built by darTZeel.

The NHB-108 has earned legendary status among critics and music lovers alike. Its immediate success and multiple awards helped to quickly establish darTZeel in the premium market. Regularly updated over a number of years and now reinvented in a «model two» version, this ultra-rapid, dual-mono amplifier is the high-end offering in the NHB series. With power output of 150 watts per channel and its circuits patented worldwide that prevent global negative feedback, the NHB-108 model two connects effortlessly with any type of speaker, unleashing its full magic and capability.

With two power supplies, two transformers, two audio circuits, and two coolers, the darTZeel model two is very much a dual-mono power amplifier in every respect. The power supply cord is the only sign that everything is housed within the one chassis.
