[Todd Anderson]

Thousand Oaks, CA, September 7, 2021 - Zesto Audio is pleased to announce the launch of their new Reference Grade Phonostage. The product is fondly known around the shop as the T-REF, which stands for the Andros Téssera Reference Phonostage.​

Andros Téssera Reference Phonostage​

Building on the success of the 2018 "Phonostage Product of the Year", the new T-REF is a complete electronic redesign of all the circuits, power supply and each component carefully curated to optimize it's potential.
George Counnas, President and Chief Engineer says, “I’m proud to give this product the Reference label. The design synergy really came together. It’s quieter, more musical and the detail from the groove is quite astonishing.” It’s the kind of product that people will say, “I never heard that from my vinyl before.”​

The Andros Téssera Reference accommodates up to 4 tonearms
with 2 MM and 2 MC inputs with fully transformer balanced outputs.
Each independent dual Mono channel has 2 sets of ground loop switches.​

What's different?​

Here are 3 main differences to the T-REF:

New ESP Supply design using 3 Toroids which unlocks the true potential of the main circuit, so it is at ease and doesn’t have to work as hard.

New tube configuration with the use of the 12DW7/ECC832, as well as 12AU7s & 12AX7s, which allows for the smoothest transition from the input section to outputs, providing the cleanest and most musical path for your signal.

New upgraded components and circuit design to deliver more musical detail, with a tighter bass, greater dynamic range, and increased headroom.
Still 100% Analog tube circuitry throughout the signal path.
