Zest-pwr

Pure Analog Power Amplifier

"Everything should be as simple as it can be, but not simpler." — Albert Einstein

Zest power amplifier expands our product line of high-value products. Exceptional quality of the Zest integrated amplifier has been preserved in a simplified package suitable for integration with a wide range of preamplifiers. Zest power amplifier features a dedicated subwoofer output expanding its applications range. Zest power amplifier is yet another meaningful product in the Vista Audio lineup.

Features

Dedicated subwoofer output
Ultrafast diodes in the rectifier circuit
Custom-made, oversized power transformer
30,000 micro Farads in the power supply filter providing large reserve of instantaneous power
Low background noise thanks to the gold-plated printed circuit board (PCB) with dedicated ground, power and signal planes
Short signal path due to judicious use of miniature surface-mount components (SMD technology)

Fundamentals are still the same: oversized custom-made toroidal transformer (built by Trafomatic), double-side metallized polypropylene capacitors at the input, and time-tested circuit topology. The result is a product that fits perfectly into the Vista Audio lineup and follows the tradition of exceptional performance and sound quality.

Please note: There are two versions of Zest, with 120 V and 230 V input voltage. These two versions are sold worldwide. The power cord does not ship with the unit: all power cords need to meet local safety regulations. A power cord with a standard “PC plug” (standard C13 connector) can be used. Minimum wire cross section of the power cord should be AWG16 (or 1.5mm²).
