CAYIN JAZZ 90 – BLUETOOTH TUBE INTEGRATED AMPLIFIER

The Cayin Jazz 90 is a meticulously handcrafted vacuum tube integrated amplifier, designed for music lovers who demand soulful analog sound and modern-day versatility.
With its selectable operation modes (TR/UL), user-selectable KT88/EL34 power tube setup and in-house manufactured upgraded toroidal transformer, the Jazz 90 embodies the spirit of tube rolling and acoustic personalization—paying homage to classic tube design while embracing audiophile flexibility and reliability.

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. Users 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 Jazz 90 is equipped with a Bias Monitoring Indicator (BMI) system. It 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 meters and top-mounted selectors for each power tube. This guarantees that bias levels remain within 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
