With the final darTZeel NHB-458, it sets a new standard: after nine years of constant research and continuous development, this amplifier, not only it owns all the qualities of the NHB-108, already acclaimed by the whole audiophile world, but it goes further in revealing a very special machine in every respect. Some key features -The output is still higher than that already showed off the proto...[more]

The most powerful amplifiers ever developed by darTZeel. NHB-468 monoblocks are the most powerful amplifiers ever designed and built by darTZeel. They are the culmination of nine years' research and development. NHB-468 mono amplifiers retain all the musicality of the original signal. The NHB-468's immense power supply ensures that they can cover the full dynamic range, providing e...[more]

The Orchestra displays stainless steel chassis with tubes mounted on  ceramic  sockets  with  golden  pins.  It  has  4  power  tubes mounted in push-pull which are driven by 2 ECC83. This unit is the result of a very thorough study undertaken by Jadis with one main objective: to make a product with all the essential qualities of a high-end ...[more]

A new power device provides the foundation for an upgraded output stage. This new transistor, first used in the Relentless Mono Amplifier, extends high frequency response, increases power handling by a factor of four and features tighter tolerance gain matching between complementary NPN/PNP pairs. A wider safe operating area and superior gain linearity provides greater thermal stability through...[more]

Abundant power is required for realistic sound quality and is a cornerstone of Dan D’Agostino Master Audio Systems’ amplifier design. The Progression Stereo continues this practice. A graceful anodized Aluminum chassis houses a 2,000 VA power supply transformer coupled to nearly 100,000 microfarads of power supply storage capacitance. Paired to this foundation is a fully complementa...[more]
