No38SL
Commentary

This is a special version of the control amplifier with new internal main parts and greatly improved sound quality.

A 4-layer board with ± power supply lines independent of music signal and ground line is adopted. By shortening the power supply line, power supply impedance is reduced and transient characteristics of the circuit are improved.

We are the first audio product in the world to use a cyanogen ester printed circuit board, a new material with excellent insulation properties used in the satellite communications field.

We put in custom-made parts.

It can be upgraded from No38L.

There was an upgrade service from No38SL to No380SL when No380SL was released.
In this version upgrade, the board and face plate were replaced, but the optical encoder was not included and the feel of the volume did not change. To change the feel of the volume, the volume part had to be replaced separately.
