Commentary
The MC type cartridge is the highest quality model of the FR-1 series.
We are the first in the world to use a pure silver coil.
Silver has the lowest conductor resistance among metals and improves electrical conversion efficiency without changing other mechanical parts.
Record sound It uses a line contact type block diamond tip that has a wide contact area with the groove wall and provides smooth tracing capability.
