Andros Téssera Reference Phonostage

Key Features For A Quieter and More Musical Phonostage

Musical Features

Completely new 100% tube analog circuit design with optimized components.
Dynamic range increased from 108dBV to 116dBV, so the quietest parts are quieter, louder parts are louder.
Loading on the secondary of the MC transformer to capture the most detail from the cartridge.
12 position MC load per channel with more finessed adjustable options like 1000, 800, 700, 500, 400, 350, 300, 250, 200, 150, 100, 50 Ohms
Two completely independent dual mono channels, with LED indicators for A and B
Gain is improved up to 7dB, which increases the output volume to better match your cartridge to your system.
The voltage increases from 250V to 300V for more headroom.
The power increases from 52W to 60W to provide more energy needed to reproduce the highs and lows of music accurately.
The amps increase from 3.4 A to 8 A to provide more current to the tubes.
Maximum output improved from 8V RMS to 12V RMS increases the headroom to allow more musical peaks like trumpet and drums.

Quieter Features

New 12DW7 tubes improves the amplification to better drive the output tubes which gives you lower noise, more headroom and lower distortion.
Dual chassis external power supply
New Toroid design ESP Supply replaces the linear regulated power supply which generates significantly less noise by concentrating the magnetic fields.
The dark black noise levels went from -90dB to -95dB.
New PCB layout with significantly more grounding for lower noise.
Dual chassis with 3-meter RFI filtered umbilical cable to eliminate external noise.
Dedicated output tubes driving high quality output transformers to create a true differential low impedance output for lower noise and ideal transfer of power to the preamp.
True floating ground, transformer balanced XLR inputs and outputs
New grounding throughout to further reduce the internal and external noise.
Switching on relays so there’s no digital chatter.
Easily adjustable MC “Load on the fly” without klicks or pops so you can hear the change
Elegantly designed 16-gauge steel enclosure to help isolate the electronic “chatter” from nearby equipment
Ground lift switches on the MC inputs on each channel to prevent noisy ground loops
All the RCA and XLR connectors are Gold plated for better conductance and lower corrosion

Other Features

Accommodates 4 tonearms, 1 MM and 1 MC per channel
All settings are saved when you switch between channels
More energy efficient Standby power that reduces the drain from 7w to 0.5W.
All switches and knobs are easily accessible, nothing hidden inside to adjust
Recessed RCA connectors are durable and will hold up to the typical Audiophile who loves to change their configuration
Each unit is hand built “Made in the USA”
50-hour factory burn in on all circuits and vacuum tubes before final testing
