Dear Music Lover,

I wanted to personally thank you for your purchase of my Andros Téssera Reference Phonostage.

I have loved music all my life – as a musician, record producer and audio engineer. That makes me fussy

about sound. That’s a good thing.

Each unit is built by hand with precision and pride to produce the most enjoyable listening experience for you.

I am proud to put my name on it and honored to share this with you.

Wishing you many happy years of listening!

Sincerely,

-- George Counnas, President of Zesto Audio

FYI:

Zesto

is Greek for hot

Andros

is a Greek island and the home of my grandmother’s family.

Téssera

is the number 4 in Greek because this Phonostage can accommodate 4 tonearms
