Cayin Jazz 90 Tube Integrated Amplifier

Presenting the much-anticipated Jazz 90

Excellence Designed and Tuned in Germany

The Cayin Jazz 90 is a meticulously handcrafted new-generation vacuum tube integrated amplifier, designed for music lovers who demand soulful analogue sound and modern-day versatility.

Its triode mode delivers intimate, refined sound, while its ultralinear mode enhances dynamics and control. It also features an MM phono input, Hi-Res Bluetooth 5.1, an integrated ESS ES9018K2M DAC, a headphone output, and a subwoofer output.

The characteristic warmth of tubes is manifested in a sonic presentation rich in harmonics, with an immersive soundstage, natural vocals, and a unique texture that only tube amplification can provide. This is complemented by superb construction, featuring select components, a robust, thick chassis, oversized transformers, and a design designed to last for decades.

This is a comprehensive solution for the modern audiophile who doesn't want to give up the soul of tubes.

Tube Configuration

At the core of the Jazz 90 lies:

• Input Stage: 2× 12AX7 / ECC83
• Driver Stage: 2 × 6SN7
• Power Stage: 4 × KT88 (switchable to EL34)

These tubes are configured in a Class AB push-pull design, offering excellent drive and dynamic capabilities across a broad range of music genres.You can also select between triode and ultralinear operating modes via a rear panel switch:

• Triode Mode: Rich, fluid midrange with natural harmonics—perfect for vocals
• Ultralinear Mode: Powerful and controlled, delivering increased headroom and energy for orchestral and electronic material.

External bias adjustment and tube selection switches allow for easy tube rolling and fine adjustment.

Bias Monitoring Indicator (BMI) & Protection

To ensure long-term performance and reliability, the Cayin Jazz 90 is equipped with a Bias Monitoring Indicator (BMI) system. This continuously monitors power tube status and activates protection in case of abnormal current. If triggered, the amp will safely shut down, protecting both the tubes and circuitry.

Bias adjustment is made intuitive with dedicated front-panel metres and top-mounted selectors for each power tube. This guarantees that bias levels remain within the optimal range at all times.

Bluetooth Connectivity

Incorporating modern convenience, the Jazz 90 features Bluetooth 5.1 with a Qualcomm QCC5125 chipset and ESS ES9018K2M DAC—supporting high-resolution codecs including LDAC, aptX HD, aptX LL, AAC, and more.

Full Remote Control

The Jazz 90 comes with a full-function infrared remote that offers convenient control of volume, mute, and input selection, ensuring a relaxed and immersive listening experience.
