Raysonic has just launched their new Supreme Series with the introduction of their new Red Maple monoblocks amplifiers. Priority in circuit design was given to achieving low noise and distortion with a wide band frequency response. KT88 power tubes were chosen in combination with a Class-AB1 ultra-linear push-pull power amplification stage.

In addition, five pairs of KT88 beam power tubes are leveraged to generate an output power of 220 watts. Five pairs of tubes provide five times the plate resistance for increased damping factor and slew rate, towards better overall performance.

The Raysonic Red Maple design is focused on direct and simple operation with minimal adjustment. All single paths are hand wired point to point circuitry with the simplest circuit designs chosen to help ensure consistency, reliability and high value.
