A 1/4" headphone jack with discrete amplification enables private listening. 

  • 2-Channel Amplifier Configuration
  • 90W per Channel Power Output @ 8 Ohms
  • Mechanical Ground Concept Chassis Design
  • Brass Speaker Terminals
  • Toroidal Transformer

The toroidal transformer in the A-S2200 is designed to provide technical proficiency and musicality. Combined with an array of audiophile-grade hi-fi features and components, this transformer helps ensure you get the musical emotion you expect.

  • Level Meters

The level meters are both a nod to the nostalgic era of hi-fi and demonstrate the return of pure hi-fi for today's enthusiasts. Visually presenting the dynamics and pulse of the music, the level meters are designed to provide a warm feeling through their softly illuminated LEDs.

  • Open Sound Stage

The open sound stage is engineered to provide a musical experience similar to being at a live performance.

  • Thick Ground Connection Wires

The amplifier's low impedance design, aided by the thick ground wires, helps present an open, natural soundstage.

  • Pure Brass Speaker Terminals

Cut directly from pure brass, the speaker terminals are designed to comfortably fit in your hand for simple tightening to provide a secure connection.

  • Mechanical Ground Concept

The A-S2200 adopts a Mechanical Ground Concept, with the bolts of the feet welded directly to the main chassis, and the large heat sink, power transformer, and block capacitors bolted directly to the chassis. This design helps maximize rigidity and avoid unwanted vibration to achieve expressive and rhythmic bass, presenting you with the groove of the music.

  • Chrome-Plated Brass Feet

The chrome-plated brass feet help complete the rigid design of the amplifier.
