Angstrom Audiolab Zenith Series ZPR22

Signal Stage and valves
The tubes used in the signal stage offer unquestionable musicality, characterized by tonal balance and a superlative level of neutrality, not forgetting the all-encompassing
three-dimensionality of the tube sound.

Best in class Printed Circuit Board
Although Angstrom Audiolab has established his reputations through their outstanding hard wired circuits this isn’t prevented them to develop a deep expertise on PCB design as well.
With the Zenith series Angstrom introduces a very high quality and performance devices, with the same component quality from the Stella series, but with the use of PCBs for a
more affordable Angstrom gem.
All the critical PCBs are complying to ENIG standard for a high performance, no compromise approach. No silkscreen is used and a special solder mask is applied manually for
achieving the maximum electrical insulation.
All of Angstrom’s PCBs are hand assembled and rigorously tested.

Solid state power supply work of art
A relevant part of the Preamplifier is no doubt the solid state power supply and the balanced topology with no useless complications making it a truly reliable system. The solid state choice affects greatly the sound quality with a very low noise.
Furthermore, not only the audio topology, but the power supply too is balanced, resulting a great silence to noise ratio that grants far less distortion on the amplification. In Angstrom the quality of the sound is always the drive, no matter the complication nor the cost.

Two Stage Circuit Topology
The circuit in designed in two different stages: the first which amplifies the signal by 6 dB and the second, amplifying once
again reaching 20 dB. Nothing in Angstrom is made for the sake of it, this particular design allows to reach an optimal
signal to noise ratio and a perfect frequency response. To maintain a low distortion a double buffer is implemented. All
in the pursuit of an outstanding audio quality, the circuit design grants a perfect amplification even for low impedances.

Ariamateria Technology
This Angstrom Audiolab device is equipped with Ariamateria high performance damping feet. Made in Italy from grits of natural stone (brown porphyry or black basalt from Trentino Alto-Adige) and bi- component biological resin.
