from Zesto Audio comes the tubed Leto Preamp, pushing the
envelope in value and performance in its price range and beyond. With
styling similar to the Andros Phono stage, the Leto is a powerful
sounding, highly detailed, fantastically quiet, and superbly musical
masterpiece that will complement the finest systems. Designed by a
brilliant and pragmatic designer who knows great sound and ergonomics,
the Leto performed like a thoroughbred in every way musical, and was a
joy to control and adjust. The fun factor while working with the Leto
made me rethink what has been missing in minimalist preamps that cost
even more money these days. What a jewel! The Zesto Audio Leto is a
killer design to my way of listening and loving recordings, and may just
be the preamp you will buy and keep for the very, very long haul.
“The Leto receives my highest recommendation.” - Robert H. Levi, Positive Feedback “I compared the Zesto Leto preamp to another line stage that cost
six times asking price of the Leto. If you wanted an instrument to
analyze music, then the higher priced unit would be for you. However, if
you want a line stage that allows you to hear the richness of music and
allows you to make an emotional connection to it, then the Zesto Leto
is for you. I easily preferred the Leto to the more expensive unit.

There are many components that claim to be bargains or to be ‘over
engineered’. The Zesto Audio products are built sensibly with truly high
quality components. The build quality alone would justify a much higher
price.

If you are looking for a line stage anywhere near the price of the
Leto, you simply have to check out this superb line stage preamplifier.
Highly recommended.” - Henry Wilkenson, Audiophilia Inputs
