Bass performance is authoritative, deep, and exceptionally well controlled. The PC-1 Supreme Mono does not exaggerate low frequencies or add artificial warmth; instead, it reproduces the weight, texture, and fundamental power contained in the groove. Double basses possess realistic body and resonance, timpani have satisfying impact, and large bass drums convey both physical scale and the distinctive character of the instrument. Importantly, the bass remains agile and articulate, preserving pitch definition and rhythmic momentum even during demanding musical passages. This combination of extension, control, and tonal accuracy gives the cartridge an impressive sense of foundation without sacrificing speed or transparency.

The midrange is richly coloured in the most natural sense, offering beautiful tonal density without sounding overly warm or romantically embellished. Voices possess convincing presence and texture, while strings, brass, and woodwinds are reproduced with a striking degree of timbral authenticity. Treble performance is extended, delicate, and highly resolved, revealing fine harmonic detail without becoming aggressive or etched.
