Cayin has expanded its high-end lineup with the introduction of the Jazz 90, a tube integrated amplifier that seamlessly blends classic tube warmth with modern connectivity. Set to debut at High End 2025, the Jazz 90 delivers a robust 2x50 watts of continuous power, enabling it to drive even more demanding speakers with ease. This amplifier not only supports traditional analog sources like turntables but also offers Bluetooth connectivity, allowing users to stream music effortlessly from their smartphones.
At the heart of the Jazz 90 are dual KT88 tubes per channel configured in a push-pull arrangement, providing a harmonious transition between signal half-waves. This design is complemented by a specialized circuitry that ensures a smooth and balanced sound output. Audiophiles can tailor their listening experience by selecting between triode and pentode modes for the KT88 tubes, and the option to upgrade to EL34 tubes is also available, offering flexibility to match personal sonic preferences. The amplifier features a bias control system with VU meters and bias monitoring indicators, ensuring optimal tube performance and longevity.
Connectivity is a strong suit of the Jazz 90, equipped with two high-level RCA inputs, a dedicated phono input for MM cartridges, and a Cinch output for a subwoofer. The built-in Bluetooth receiver supports high-resolution codecs like aptX HD and LDAC, facilitated by an ESS ES9018K2M DAC that handles the digital-to-analog conversion exclusively for Bluetooth signals. While it lacks digital inputs such as TOSlink or coaxial, the front-accessible headphone jack provides a versatile option for private listening. The speaker terminals are gold-plated and accommodate both 4 and 8-ohm configurations, catering to a wide range of speaker impedances.
The Jazz 90’s construction reflects Cayin’s commitment to quality, available in sleek black or silver finishes. Priced at €2,998, the amplifier is expected to be available by the end of June 2025. With its combination of powerful tube amplification, versatile connectivity, and customizable sound settings, the Cayin Jazz 90 is poised to attract audiophiles seeking both nostalgia and modern functionality in their high-end audio systems.
