A real new-generation class-D amplifier
with latest highly accurate PWM switching devices

By employing the latest developed class-D amplifier devices, power MOS-FET achieves ideal highly accurate current switching in the power stage, and high-voltage gate driver IC with excellent time-axis control maximizes the ultimate PWM switching. The exceptional performance of the class-D devices ensures ultimate real-sound with quality damping in the mid to low ranges even when driving low-efficiency speakers. Furthermore, the sweet and rich tonal character in the mid to high ranges of the amplifier is almost like the tone of the best triode tube amplifiers.

Superb power source of RSA-F33EX / RSA-M3EX / RSA-V1EX ensures the real musical sound

In order to maximize the potential of the unprecedented high performance of this amplifier (power utilization in the power stage at maximum output; 96%), we daringly employed a classical and very simple plus/minus power source composed of minimal numbers of high quality components, such as only transformers, bridge-diodes and capacitors.

Specially selected parts of low-pass filter contribute to the Real-Sound

The sound of this class-D amplifier owes a lot to the individual parts of low-pass filter in the final stage of the amplifier. The capacitor and the coil employed for the low-pass filter were custom-ordered after careful listening tests and guarantee the excellent musical sound of RSA-F33EX / RSA-M3EX / RSA-V1EX. Above all, many custom hermetic seal paper-oil filled capacitors are employed in the low-pass filter and snubber circuit of RSA-F33EX because of the natural and vivid character of the sound only those old type capacitors have. These paper-oil filed capacitors have been supplied to the aerospace industry for the past half century and made to meet the strict MIL standards for getting the highest reliability.

Wooden base-chassis and insulators to realize rich and beautiful instrument-like sound

In an unusual endeavor for an audio amplifier, natural wood was used for the base chassis and insulators.
Base-chassis of RSA-F33EX: A solid laminated panel of European spruce from Austria was used for the under-base. Spruce has long been used for the top plate of stringed instruments and the soundboard of pianos, and is known as a material with excellent sound quality that provides quick vibration trans-mission and moderate damping.
The combination of this material with the rigid steel chassis produces a rich pleasant sound.
Insulators of RSA-F33:Three insulators combine pure painted maple from Hokkaido, Japan and hickory from North America. Maple has excellent strength and is used in combination with spruce for the sides and backs of stringed instruments. Hickory is a hard material that absorbs impact well and is used for drumsticks for example. The maple and hickory insulators moderate the vibrancy of the spruce material and help provide rich musicality.

The rich, sweet tone and exceptional powerful RSA-M3EX′s “Real-Sound” realizes true delight of music

Two types of oil-filled capacitor used in low-pass filter reproduce both tonal characteristics of finest vintage tube amplifier′s tone and above all modern vivid sound

  • Two types of custom oil-filled capacitor made in USA by Arizona Capacitors, Inc. and exceptional high quality mica capacitors are adopted in the final stage of the amplifier′s circuit for the best suited reproducing any kind of music with deep, tender and also fresh tone for our hearing.
  • Custom made inductor featuring special ring core selected only by hearing allows the low-distortion and like an open air sound through the entire range.

Outstanding power source ensures high quality and dynamic sound of RSA-M3EX

  • The latest SiC (Silicon Carbide) schottky diodes, designed to completely eliminate switching noise,
    achieve not only transparent, beautiful but also very powerful and clear-cut low-range.
  • Multiple electrolytic capacitors with different audio characteristic are used in parallel to ensure a well-balanced sound across the entire range. In addition, high voltage paper-oil filled capacitors, connected in parallel to improve the characteristic of ESR (Equivalent Series Resistance), achieve a precise and fascinating tone over the mid to high-range.
