Cayin JAZZ 70 EL34 Integrated Tube Amplifier

Classic EL34 tube sound meets modern wireless convenience.

The Cayin JAZZ 70 is a refined integrated tube amplifier created for listeners who want the warmth, texture, and musical character of traditional vacuum-tube amplification without giving up modern-day convenience. Combining an elegant retro-inspired design with Bluetooth 5.1, selectable operating modes, and handcrafted construction, the JAZZ 70 brings classic tube amplification into the contemporary home audio system.

At its heart is a classic Class AB1 push-pull tube design, featuring three 12AU7/ECC82 tubes in the preamplifier stage and four fully matched EL34 output tubes. This carefully selected tube complement delivers the rich tonal character and expressive musicality associated with EL34 amplification while providing enough output capability to partner with a wide variety of loudspeakers.

Two Distinct Listening Modes

Tailor the JAZZ 70's presentation to your music and system with selectable Triode and Ultralinear modes.

Triode Mode — 17W + 17W RMS
Designed for a smoother, more intimate and refined presentation—ideal when tonal richness and nuance take priority.

Ultralinear Mode — 35W + 35W RMS
Provides additional power, dynamics, and control for a more energetic presentation and greater flexibility with different loudspeakers.

Premium Transformer Design

Cayin equips the JAZZ 70 with a specially designed, handmade low-magnetic-leakage toroidal power transformer along with wide-frequency-response EI output transformers. These components help provide stable, clean power delivery, broad frequency response, and the natural tonal character expected from a high-quality tube amplifier.

High-Fidelity Bluetooth 5.1

The JAZZ 70 makes wireless listening easy without abandoning its audiophile focus. Its built-in Bluetooth section uses the Qualcomm QCC5125 chipset together with an ESS ES9018K2M DAC, allowing music to be streamed directly from compatible smartphones, tablets, and other devices.

Supported formats include LDAC, aptX HD, aptX LL, aptX, AAC, MP3, and SBC, giving listeners extensive options for high-quality wireless playback.

Classic Dual-Function Meters

The distinctive front-panel meters are more than a retro visual touch. They also provide practical bias adjustment and bias monitoring functionality. During playback, their movement adds to the unmistakable visual appeal of a traditional tube amplifier.

Handcrafted for the Tube-Audio Enthusiast

True to Cayin's traditional approach to tube amplification, the JAZZ 70 features hand-made construction with fine point-to-point wiring. A removable metallic tube protection cage is included for added safety while maintaining the amplifier's classic appearance. A headphone output and supplied remote control add further everyday versatility.
