Music spawns from something emotional. A unique, personal story an artist wishes to share. Understanding how music is created, and indeed helping artists to create, embeds in Yamaha’s DNA a fundamental understanding of music, particularly the emotion upon which music creation is inspired. In the development of each of our extensive range of Hi-Fi products, conveying this emotion to the listener is one of the most important considerations.
Toroidal Transformer
large toroidal transformer has been used in the A-S3200 in the pursuit of pure musicality. With less flux leakage there is no negative impact on other sensitive audio circuits, while the copper wire is directly drawn from the winded core, minimizing energy loss compared to other substitutes, allowing the full emotional energy in the music to be felt by the listener.
Thick Wires for Ground Connection by Low Impedance Concept
Adopting low impedance design concept minimizes both energy loss while maintaining absolute integrity in the audio signal. Preservation of the original audio results in an open, natural sound stage, bringing the listener and the artist together.
Following an intensive forging process, the PC-Triple C speaker wire has an inherently more linear structure, allowing for smoother signal transmission to more accurately present the original musical recording.
Feeling the music. Not just feeling like you are there, but feeling the story in the music. Feeling the rhythm, the groove of the music. Moving with the music. Only a true representation of the music can deliver this.
Mechanical Ground Concept
An expression of deep, rhythmic and melodious bass generates feeling from the music, the story of the music. The Mechanical Ground Concept achieves this expressive and rhythmic bass by maximising rigidity and reducing any unwanted vibration. The large power transformer, block capacitors and heat sink are directly bolted to the chassis delivering greater rigidity, while the feet, with bolts directly welded to the main chassis, provide further reinforcement for absolute rigidity. The A-S3200 has an original Rigid Streamlined Construction that further suppresses vibration.
Silver Plating Brass Feet
Completing the rigidity of the amplifier are the heavy-duty brass feet used with either spikes or the scratch-resistant base for delicate surfaces, originally engineered exclusively for the flagship M/C-5000.
