7 New Features of the Leto Ultra Preamplifier

1. 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.

2. 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.

3. 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 control.

4. 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.

5. 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.

6. 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.

has a unique  t Presence Control, which was born out of my frustration after finding some of my favorite recordings became unlistenable the more resolved my system became, regardless of the source. This new feature deals with the harmonic balance of the mid and high frequencies. Now I can easily adjust the balance for every song.

I have been enjoying this in my own listening and am certain you will too.

Focus on the Music

With the Leto in your system it will allow the sonic detail to come through, so you focus is on the music and the hardware will seem to disappear.
