About the Leto
The Zesto Audio Leto is an all-analog, vacuum-tube line preamplifier. The original Leto uses two 12AX7 input tubes and two 12AU7 driver tubes, with polypropylene capacitors in the audio path and transformer-coupled balanced connections. It provides three single-ended and two balanced inputs, plus single-ended and balanced outputs; one single-ended input is linked to cinema-bypass outputs for integration with a surround processor. The original model was later superseded by the Leto 1.5 and Leto Ultra generations, so its specifications should not be confused with those newer versions.
