darTZeel NHB-108 Model Two
From AUD $95,000.00
Stereo (Twin Mono) Power Amplifier
Although the darTZeel NHB-108 Model One power amplifier was first introduced in New York in 2002, it had taken Hervé Delétraz over 16 years research to ready it for production. It was immediately recognised as the most advanced amplifier ever designed, a description that the modern incarnation, the NHB-108 Model Two still carries. 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.
Hervé Delétraz meticulously explored the possibilities for reproducing music in all its emotional richness and splendour. The end product is an electronic audio circuit that has been greatly trimmed back to offer exceptional simplicity, which no one before thought possible.
The NHB-108 is the ultimate dual-mono power amplifier. In the relentless pursuit of perfection, everything must be considered down to the slightest detail. With two power supplies, two transformers, two audio circuits, and two coolers, the darTZeel model two is very much a dual-mono design in every respect. The single power supply cord is the only sign that everything is housed within the one chassis. 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.
darTZeel amplifiers delight not only in terms of how they sound, but also how they look and feel. Through its toughened mineral glass panel, one can admire the fine-brushed, crescent-shaped bus bars made from 24-carat gold and the carefully partitioned internal layout that gives this exceptional amplifier its unique character.
The sonics of this amplifier are communicated in its part number ‘NHB’ (Never Heard Before) and one audition will reveal the truth of this statement. The sound has a warmth and naturalness that convinces people that they are listening to a high-quality tube amp yet at the same time a speed and dynamic headroom that convinces them that it is in fact a high-powered solid-state amp. It reveals in fact, just how limiting our references and discourse has been in the world of audio reproduction, reveals in fact what is possible.
The NHB-108 Model Two is a revelatory product that simply has no sonic equal. It awakens the senses and opens a portal to an invigorating, engaging musical experience. Superb!
