Superb stereo separation and imaging
Big, full, open sound on live recordings.
The Andros PS1 was very quiet. In fact, it made the solid state ASR appear to have a bad case of tube rush by comparison. Stereo
separation was also quite spectacular.
The sound of the entire Catch Bull at Four LP ... was nothing short of spectacular.
Superb dynamics, holographic imagery, and ability to cleanly and clearly deliver highly complex passages without losing its composure.
I recommend the Zesto Audio PS1 without reservation.
Dagogo 2012 (Ray Seda)
The Andros PS1 has a tonal correctness that becomes more evident as the hours go by. There is a sense of flow, with notes flowing up
and out of the presentation, distinctly rendered. Oboes sound like oboes, not squawky and violins sound natural, not squeaky or harsh.
The soundfield produced by this phonostage is humungous and it helps to make the speakers disappear that much easier."
Comparing the Andros PS1 to a few higher priced phonostages (the ARC REF Phono 2, Pass XP-25 and Sim 810LP) and a few lower (Manley Chinook, EAR 834P and Sim 310LP) reinforce that the pricing of this unit is indeed spot on.
After a solid month of intense audition, the Zesto Andros PS1 exhibits no weaknesses whatsoever.

כיוונון נוח במיוחד לכל סוגי הראשים
MC Low Output ועד MM החל מ
It’s one of the loveliest-sounding electronic components I’ve ever
had the pleasure of reviewing. Almost miraculously, it seems to
exhibit virtually no discernable electro‑mechanical artifacts.
Its sound is unbelievably smooth and velvety; harmonically rich, full,
and vividly textured; marvelously rounded, tactile, and dimensional,
with great body and solidity; and completely natural in its musicality
and freedom from any of the usual sonic hype, audiophile style.
There is also an extraordinary homogeneity to the presentation...
The Absolute Sound 2012 (Paul Seydor)
All three Stereomojo reviewers agree: The Andros Phonostage,
made in the USA by new company Zesto, is a remarkable achievement
both in terms of absolute performance as well as artistic form and
function. If you have a significant investment in vinyl and an
analog front end that merits the best of the best phono preamps,
you should by all means audition the Zesto Andros. At its price,
its performance competes with much more expensive units. In
appearance and sexiness, there’s nothing that comes close.

Out of the box, the Andros Téssera produced luscious mids that immediately dominated the music,
producing in that region a glorious, golden, airy sound...
It's among the more enjoyable and satisfying phono preamplifiers I've auditioned at any price.

Sonic magic
The Absolute Sound 2013 (Paul Seydor)
You like super smooth, delicate highs, with pinpoint imaging Then you will love the Leto.
The high frequencies are both sophisticated and realistic, with an almost grainless presentation.
The blacks are the blackest in its class, and this is a tube unit, too! This is an amazingly quiet design.
Never edgy or unnecessarily crisp, cymbals, violins, flutes are all ultra-natural.
Soprano vocals are superbly rendered. In my experience, overall high band definition cannot be bettered in this price range.
