Basics Rule

 

My design philosophy is to focus only on the important components and add nothing that could compromise the signal path. The only active components are the vacuum tubes that create a warm musical sound.

Balanced Means Lower Noise

As a longtime audio engineer and producer, I’ve worked with a lot of professional equipment. I always preferred “true floating balanced” inputs and outputs because of their foolproof ability to isolate one piece of gear from the next. 
And that means lower noise for a strong, clean and quiet signal.

Easy to Use

The Leto preamp will compliment most systems: tube, solid state or digital. It will work with single-ended and balanced input source or power amplifier combinations.

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.

What is Leto?

In Greek mythology, Leto is the mother of Apollo.

 

Key Features

 

  • Plenty of volume to handle all your source material .
  • The input selection uses only electromechanical switching to provide the most musical detail.
  • The wide frequency response allows you to hear the finest passages in your music.
  • True floating transformer balanced Inputs and Outputs have lower noise and isolate one piece of gear to the next.
  • Left and Right ground switches allows you to control the grounding of the single ended outputs.
  • The output transformers provide a strong and clean signal to your power amplifier.
  • Recessed RCA and XLR connectors are high quality, Gold plated, with an isolated ground.
  • All connectors are durable and will hold up to the typical Audiophile who loves to change their configuration.
  • No pops when the unit is turned on or off.
  • Automatically goes to mute when turned on or off.
  • Remote control Volume, Mute and Mono
  • The remote Mono helps you to trouble shoot your system.
  • Remote bypass switch overrides the mute in case the remote is misplaced.
  • 50 hour factory burn in on all circuits and vacuum tubes.
  • Elegantly designed 16 gauge zinc plated steel enclosure to help isolate the electronic “chatter” from nearby equipment.
  • On/Off power switch conveniently mounted on front side panel.
  • Each unit is hand built "Made in the USA".
