Adjusting sound quality for each set by hand:
Sony original acoustic tuner
In addition to measuring each set meticulously during the manufacturing process, adjustment of
acoustic resistance material to constant values is also performed by hand. To achieve ideal
characteristics, only items that clear strict sound control requirements are shipped. Persistent detailed
tuning with precision controlled acoustic tuning components and original Sony acoustic tuners ensure
sound quality control at a level of precision higher than ever before.
Suppressing transmission loss of music signals:
High grade N-OFC Litz cord
The cord for transmitting the signal uses grade 7N OFC (Oxygen Free
Copper) of extremely high purity (99.99999 %). Suppressing signal loss in
the cord minimizes sound degradation.
