A Four 1200

Our high-end Integrated Amplifier is the ultimate bridge between accessibility, practicality and uncompromising sonic excellence. Designed for those who demand the best, it brings together the ease of use with the artistry of sound, transforming your listening experience into something truly extraordinary. Every detail is carefully crafted to deliver a dynamic and immersive soundscape, while maintaining a compact design that fits effortlessly into any environment. With power and precision, it elevates every note, every chord, making each moment of music feel vivid, alive, and deeply personal. This is where sophistication meets simplicity, redefining what it means to truly hear.

The A Four I200 stereo amplifier from the Absolute line inherits the technology developed by Orpheus Lab for the Opus II of the prestigious Heritage line. It features a current amplification stage driven by six high-power MOSFETs, meticulously hand-matched for each channel, capable of reaching instantaneous current peaks of up to fifteen amperes. To ensure optimal control throughout the amplification chain, each MOSFET is governed by a bipolar technology control stage. This approach, combined with a multi-point feedback topology, allows for the precise application of feedback, achieving a perfect balance between musicality and technical performance. As a result, the A Four I200 adapts seamlessly to any type of loudspeaker.

The Class AB architecture is brought to life by a carefully calibrated 125 mA bias current, delivering a thermal idle power of 15 WPC and allowing the amplifier, at rest, to stabilize at 15 °C above ambient temperature. To guarantee flawless power delivery, each amplification channel is powered by an oversized toroidal transformer with a capacity of 880 VA. The polarization circuit ensures optimal biasing regardless of the operating temperature. Furthermore, its low impedance BJT component architecture maintains constant biasing irrespective of the load type, even at the highest current peaks.

The integrated preamplifier of the A Four I200 is equipped with six analog inputs, each featuring an input level selection stage (High, Med, or Low). This flexibility ensures optimal adaptation to the wide variety of sources available on the market. Volume control is entrusted to the renowned PGA2320 integrated circuit, whose implementation has been meticulously optimized to fully unleash the musical expression. Every nuance, every detail, unfolds with grace and power, revealing the soul of the music in its most vivid depth, offering discerning listeners a sound experience of rare intensity.
