Zest
Pure Analog Integrated Amplifier

..

"Strive no to be a success, but rather to be of value." [Albert Einstein]

.
Vista Audio continues to create high-value products and, as proven by our Spark integrated amplifier, products offering great value trace the path for great success. Zest integrated amplifier is another Vista product firmly standing on that path.

FEATURES:

- ALPS Blue Velvet potentiometer for volume control
- Ultrafast diodes in the rectifier circuit
- Custom-made, oversized power transformer
- 30,000 micro Farads in the power supply filter are 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 the judicious use of the 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.
