The Ultimate Guide to Sansui Amplifiers: The Grandest Models148

Sansui, a legendary Japanese electronics manufacturer, has been crafting exceptional audiophile equipment for decades. Their amplifiers, renowned for their exquisite sound quality and unparalleled craftsmanship, have become the cornerstone of high-end home audio systems worldwide. Among Sansui's illustrious lineup, the highest-tier models stand as true masterpieces, offering a symphony of sonic excellence that will captivate even the most discerning audio enthusiasts.

The journey to the summit of Sansui's amplifier hierarchy begins with the AU-111, a hallowed model that set the benchmark for audiophile performance in the mid-1960s. This fully-transistorized powerhouse boasts an impressive power output of 120 watts per channel, delivering effortless clarity and dynamics. Its meticulously engineered circuitry and meticulously selected components ensure an unparalleled depth and richness of sound.

As Sansui's engineering prowess advanced, they unveiled the AU-20000, a magnificent amplifier that pushed the boundaries of sonic excellence. Released in 1973, this masterpiece employed a revolutionary dual-mono design, featuring two independent power supplies and signal paths for each channel. This ingenious architecture resulted in exceptional channel separation and a breathtakingly spacious soundstage.

The AU-717, introduced in 1977, further refined the dual-mono concept and introduced a host of innovations that became synonymous with Sansui's highest-end models. This amplifier's power output was increased to 240 watts per channel, providing an abundance of headroom for even the most demanding speakers. Its sophisticated "Super Feedforward DC" circuitry eliminated distortion and provided an unparalleled level of purity.

The AU-9900, released in 1980, represented the culmination of Sansui's decades-long pursuit of audio perfection. This flagship model featured a formidable power output of 330 watts per channel, coupled with an exceptionally wide frequency response and vanishingly low distortion. Its "X-Balanced" circuitry, a Sansui exclusive, ensured unmatched linearity and dynamic range.

While the AU-9900 marked the pinnacle of Sansui's amplifier development, the company continued to innovate, releasing a series of highly acclaimed models that further cemented their legacy. The AU-α907XR, introduced in 1984, showcased advanced Class A circuitry and a unique "MOS-FET" output stage, delivering unparalleled smoothness and refinement.

The AU-α907i, released in 1986, marked a technological breakthrough with its adoption of "MOS-FET" technology for the entire power amplifier section. This innovative approach resulted in a remarkable reduction in distortion and an unprecedented level of transparency.

Sansui's pursuit of sonic excellence extended beyond the realm of traditional power amplifiers. The BA-3000, released in 1984, was a groundbreaking integrated amplifier that combined exceptional audio performance with a plethora of features. Its built-in equalizer, phono stage, and digital input made it a versatile hub for any music system.

The C-2302 preamplifier, released in 1986, was the perfect companion for Sansui's highest-tier power amplifiers. Its minimalist design concealed a wealth of advanced features, including a fully balanced signal path and a sophisticated phono stage that accommodated both moving magnet and moving coil cartridges.

Today, Sansui's vintage amplifiers continue to be highly sought-after by collectors and audio enthusiasts alike. Their exceptional build quality, timeless designs, and unparalleled sonic performance make them enduring testaments to the artistry and innovation that have defined the Sansui name.

As you embark on your journey to acquire the ultimate Sansui amplifier, it is essential to consider your system's specific requirements and your personal preferences. Whether you seek the raw power of the AU-111, the refined elegance of the AU-717, or the groundbreaking advancements of later models, Sansui's highest-tier amplifiers offer a symphony of sonic excellence that will elevate your listening experience to unprecedented heights.
