Underwood Hifi is glad to announce that we are now selling Zesto Audio. We love their all American made products and while not inexpensive, we feel they offer a real value in the crazy world of insane hi-end pricing.

George Counnas designs great sounding products. His phono stages are second to none and the Leto Ultra preamp featured in this ad is our favorite tube preamplifier at even double its cost. We were shocked at how much better it sounded than our previous big selling PS BHK preamp. The unique contour control even makes poorly recorded music sound good on highly resolving systems.

This new Leto II version gets an upgraded ESP power supply. It is quieter and even more dynamic than the model it replaces.

We can give you $4500.00 in trade for your a PS BHK. 

In the Feb 2020 review by Positive Feedback Robert Levi says:

"The Zesto Audio Leto Ultra Preamplifier is Zesto Audio's ultimate
statement of preamplifier perfection. It is made 100% in America. The
all-tube unit is chock full of useful and creative features a dedicated
audiophile and music lover will enjoy, styling which would be right at
home at MoMa, a flexible remote control without flaws, and Zesto's best
overall musical performance to date. Sonically superior to anything
solid state I have ever heard, you would have to spend a ton more to
equal its high definition and many features in the tube world."

tube preamp at any price is quieter or has better facilities to manage
hum and noise in your entire system like the Leto Ultra. The Leto Ultra
is one superior innovative product, and right at home in the Zesto line.
My highest buy recommendation!"

Here are a few other quotes from the review:
created a preamplifier that is neutral with a bullet, remotely
changeable to enhance lesser recordings or sources, has remotely
adjustable outputs that provide unity gain with no editorializing, and
uses fully balanced tube circuitry throughout...all on one normal-sized
chassis. Plus, it is a 100% ultra-quiet advanced tube circuit super easy
to roll. Joining
the Bia amplifier and the Andros Deluxe phono, the new Leto Ultra
preamplifier premiers in excellent company—the three most innovative and
dramatic advances to date of AFFORDABLE state of the art musical
reproduction in the home."

Leto Ultra soundstage is grand. From ceiling to floor and wall to wall,
and front to infinity, the speakers disappear and the music flows. With
a state-of-the-art source, expect a state-of-the-art performance from
the Leto Ultra."

The new 2019 Ultra version replaces the extremely well reviewed Leto 1.5. From their website:

has announced their newest, all analog product - the Leto Ultra
preamplifier, which replaces the discontinued Leto 1.5.
Of particular interest are the 'tone controls', the new Presence
Control. George Counnas says, “This was born out of my frustration that
the more resolved my system became, many of my favorite new and old
recordings, became unlistenable due to the inconsistencies of the
Mastering, regardless of the source. I realized the part that bothered
me was the harmonic balance of the mid and high frequencies, the region
that can be considered too bright, edgy, aggressive or fatiguing.” The 6
position Presence control easily allows you to dial it back without any
technical knowledge required, just listen for the most enjoyable tonal
balance for every song. George says, “It works great for your mood too,
because sometimes I’m in the mood for lots of detail and sometimes I
want it laid back and I can do it from my sofa with the remote.

Top 7 New Features of the Leto Ultra Preamplifier

New upgraded circuit topology delivers more musical detail with a
tighter bass. It has a robust input design to handle higher output
sources. Dynamic range is expanded by new circuitry that produces a
higher output before distortion. Still 100% Analog tube circuitry
throughout the signal path.

New tube configuration with the 12DW7 allows for the smoothest
transition from the input section to outputs, providing the cleanest and
most musical path for your signal.

New 3 gain positions 3dB, 6dB and 9db make the Leto Ultra one of the
most versatile preamps available. It easily accommodates the many volume

differences from all your sources such as a high output DAC, as well as a
low output phono. Your preferred gain settings are saved on each input
and can be conveniently adjusted “on the fly” with the Remote or Manual

New 6 inputs for your many sources include 3 true dedicated transformer
Balanced Inputs and 3 Single Ended. All are high quality, gold plated
connectors for better conductance and less corrosion for the most
reliable connection.

New 6 Position Presence Control adjusts the harmonic balance in the mid
and high frequencies allowing you to dial back what you may consider to
be too bright, edgy or aggressive. This is an exceptionally useful tool
that addresses the inconsistencies of mastering from any source. It’s
easily adjustable “on the fly” with your remote or manually for each
piece of music.

New 9 button Remote control to conveniently adjust “on the fly” settings
including Input, Volume, Presence, Mute, Mono and Gain. In case you
misplace your remote, all features can be adjusted manually.

7. New LED indicators on the front panel clearly display all your adjustments.

In the first review of the original Leto Positive Feedback summed with:

"The Zesto Audio Leto 1.5 Vacuum Tube Preamplifier bests the 1.0 in
features and in every parameter I can think of. It hosts improvements in
the highs, mids, and bass which will mightily please audiophiles. It
has improved definition and neutrality. It makes the music live in your
high-end system. Plus, it is not more expensive, just improved and
perfected! It even sports an excellent headphone output jack on the
front panel for added pleasure. The 1.5 is a real keeper in my book and
worthy of any system no matter how expensive.

This new Ultra preamp is another step forward in sounics and features
My congratulations to Zesto Audio. They did it again! Most highly recommended."

Stereophile summed the original Leto review with:

was very impressed with the Leto. Zesto Audio has produced a well-made,
stunningly gorgeous product that gave me hours of pleasure as I
listened to a wide range of recordings. In this crazy market of
ever-increasing prices, a tubed line stage with so many strengths, so
few and negligible weaknesses, and that can produce this level of
musical satisfaction without costing somewhere in five figures, is
commendable. In that sense, the
Zesto Leto line stage is a veritable bargain." 

Other Important Features you may want to know about:

  • Automatically goes to mute when
    turned on or off, preventing any pops which could damage your speakers
    or surprise the hell out of you.

  • Each preamp receives 50 hours of factory burn in on all circuits and vacuum tubes.
