Product Brand : darTZeel
Product Name : NHB-108 Model 2 Amplifier
Product Genre :
Condition : NEW
Description:
We consider our products to be musical instruments.
 
When an exacting musician—do non-exacting musician exist?—visits an instrument maker, technical discussion cannot always be avoided. At the end, the choice will be influenced by those more down-to-earth, we would say, considerations.
 
The high speed, dual mono power amplifier from darTZeel is not an exception to the rule. Technology matters, and makes a difference. But rather than claiming extravagant virtues which may be more or less verifiable, we much prefer to show you the facts, and only the facts.
 
Some review:
 
If you discovered the darTZeel NHB-108 model one for the first time through our web site, it may be helpful to recall some design basics:
 
    * No global Negative Feedback
    * Open-loop input and output stages
    * No relay, switch, fuse or the like in the whole signal path
    * Only 6 transistors per polarity side, from input to output
    * One single bipolar-transistor output pair
 
The five key design elements listed above are of course not exhaustive. But they do reflect the extreme care we put into the concept. We envisioned every detail of the complete design with only one thing in mind as being of paramount importance: All drawings and schematics concerning the darTZeel NHB-108 model one are copyrighted and patent-protected.
 
The most musical reproduction possible, with the highest fidelity regarding the audio signal.
