XTZ Class AP100
Class A Power Amplifier

XTZ Class AP100

Class AP100 silver / A powerful amplifier with finesse

Class AP100 is a pure power amplifier capable of delivering high end sound to your loudspeakers. AP100 offers you the possibility to switch between class A mode for maximum sonic performance, or class AB for maximum power. The AP100 is a robust yet technically advanced product giving the listener a perfect balance between performance and a long life span, which guarantees many years of trouble free use.

A few key properties for AP-100:

  • New circuit board layout
  • Shielded design for each internal section 
  • All inputs and outputs are gold plated high quality units
  • Symmetrical circuitry 
  • Balanced input
  • Bridged mode option

Class A or Class AB
Class AP100 is constructed to let you select class A or class B mode. If you want to focus on lower power consumption, select class AB mode and if you want maximum sonic performance select class A.

Technical presentation
The amplifier is equipped to offer you top end performance. All inputs and outputs are gold plated high quality units. A powerful toroidal transformer guarantees an efficient power supply.

All sections are separately shielded to minimize cross hearing and interference. Twin differential input stages and fully symmetrical circuitry through the complete signal path ensures perfect performance. The differential circuitry helps suppress distorsion, especially the odd overtones. The output stage itself provides High End performance thanks to the use of fast bipolar transistors from Toshiba, which are also capable of very high output currents and handling tricky load impedances. 

The cabinet
The new cabinet design, with its softer and smoother edges, is in all essential parts made from highly stable aluminum. This enhances the impression of quality and provides a rigid construction. Outer interference is effectively shielded, and the aluminum helps with heat dissipation, spreading it evenly through the amplifier.
