Ayre K-3

Commentary

This is a preamplifier that condensed the essence of sound design and realized a more reasonable price.

Equipped with two 1 dB step pure silver 46 contact resistance switching attenuators.

The amplifier circuit is a fully discrete configuration using FET.
A non-NFB configuration is provided up to the power supply.

The power supply section uses a choke input filter to reduce RF noise.

Direct Path Technology is thoroughly applied. Input / output terminals are directly attached to the board and devices are surface mounted.

It has a simple structure with no internal wiring as much as possible.

The volume part uses a mechanical volume by belt drive to ensure high reliability and high sound quality.

The power supply unit is contained in a separate case to reduce interference with the circuit.

Wireless remote control is included.

An optional discrete phono amplifier can be set up in the enclosure.
