DarTzeel true passion for music reproduction, which they have nurtured for 25 years, led us on a long quest to design an audio amplifier that can convey the emotions at the heart of a musical performance.

Absolute sounds are proud to introduce the long-awaited result, the darTZeel NHB-108 model one stereo amplifier.
Most consumer products today—even some very expensive audio components—are designed primarily from the standpoints of manufacturing efficiency and cost savings.

At darTZeel, the only question to be answerted is: Does it make the music feel real?
Their  drove us to spend 16 years researching and developing every possible aspect of a new audio circuit, embodied in a completely new amplifier.
Amplifier circuits have, in the past, usually been considered to be relatively simple.
You can be assured that for us to spend 16 years on one design, “measured performance” alone was not our only goal. Please download and read at your leisure DarTzeel’s “Audiophile’s Manual”from http ://  which tells the epic tale of their quest!
Their products, before anything, are designed and realized from a purely humanistic point of view. For us, music is not only a means for communicating and listening. Far more than this, for us music is a powerful means of soul expression—even of spiritual development.
Emotions that music generates are to be carefully taken in account in the design process. Technology is only then applied to enhance the emotions, even transcend them, without altering them.

Once that goal is reached, DarTzeel can concentrate on the "electrical performance" aspect. This is DarTzeel test bench.

Listen first, measure later.
Never the other way around.
That is the way we design our products.
The darTZeel NHB-108 model one is our first commercial product. You can be assured that others will soon follow…

We invite you to discover the darTZeel NHB-108 model one through one of our studio dealers
