Cayin Jazz 70 EL34 Integrated Tube Amplifier

 Meet the new Jazz 70

Classic Valve Sound Meets Modern Connectivity

The Cayin Jazz 70 is a beautifully handcrafted integrated tube amplifier that combines the unmistakable warmth and musicality of EL34 valve amplification with the convenience of today's digital technology.

Designed as the ideal entry point into premium tube audio, the Jazz 70 delivers exceptional performance through traditional point-to-point wiring, selectable Triode and Ultralinear operation, high-resolution Bluetooth streaming and meticulous hand-built construction.

Available in Silver or Black, the Jazz 70 offers timeless style and sophistication together with impressive versatility and an engaging listening experience that brings your music to life.

Handcrafted EL34 Performance

At the heart of the Jazz 70 are four carefully matched EL34 output valves operating in a Class AB1 push-pull configuration, partnered with three 12AU7 (ECC82) valves in the preamplifier stage.

Renowned for their rich harmonic character, smooth midrange and natural musical presentation, EL34 valves have long been a favourite amongst audiophiles. Cayin complements this classic design with traditional point-to-point hand wiring throughout the amplifier, providing a shorter, cleaner signal path while showcasing the craftsmanship that defines premium valve amplification.

Two Distinctive Listening Personalities

One of the Jazz 70's standout features is its ability to switch instantly between Triode and Ultralinear operation, allowing you to tailor the amplifier's character to your music and loudspeakers.

Triode Mode

Operating at 17 watts per channel, Triode mode produces a beautifully smooth and intimate presentation. Vocals become more lifelike, acoustic instruments gain texture and recordings are reproduced with exceptional warmth and finesse. It's the perfect setting for jazz, folk, vocals and relaxed evening listening.

Ultralinear Mode

Switch to Ultralinear mode and output increases to 35 watts per channel, delivering greater dynamics, improved bass authority and increased control over more demanding loudspeakers. This mode is ideal for rock, orchestral recordings and larger listening spaces where extra power and headroom are beneficial.

With the flick of a switch, the Jazz 70 offers two distinctly different listening experiences within the one amplifier.

Superior Quality Transformer Design

Powering the Jazz 70 is a handcrafted toroidal power transformer designed to minimise magnetic interference while supplying exceptionally clean, stable power to the amplifier circuitry.

Complementing this are Cayin's custom EI-core output transformers, engineered for wide bandwidth and excellent linearity. Together they contribute to the amplifier's impressive frequency response of 8Hz–60kHz (-3dB), delivering superb detail, openness and natural dynamics across the audible spectrum.

Complete with High-Resolution Bluetooth Streaming

While firmly rooted in traditional valve amplification, the Jazz 70 embraces modern digital convenience with integrated Bluetooth 5.1.

Using the Qualcomm QCC5125 Bluetooth platform together with the acclaimed ESS ES9018K2M DAC, the Jazz 70 provides wireless playback quality worthy of a serious hi-fi system.

Supported codecs include:

• LDAC for high-resolution wireless audio up to 990 kbps
• aptX HD for 24-bit Bluetooth playback
• aptX Low Latency for synchronised video audio
• aptX
• AAC
• SBC

Bluetooth operates over a range of approximately 10 metres, making it easy to stream music directly from compatible smartphones, tablets and computers.

Functional Dual VU Meters

The illuminated twin VU meters provide more than vintage-inspired aesthetics.

During playback they display real-time output levels for each channel, while also acting as the bias monitoring system for the EL34 output valves. This allows straightforward tube bias adjustment, ensuring the amplifier continues to perform at its optimum throughout its life.

Built for Everyday Listening

The Jazz 70 has been designed to fit effortlessly into modern listening rooms.

A dedicated headphone output comfortably drives headphones from 16Ω to 300Ω, making private listening just as enjoyable as speaker-based playback.

For convenience, a full-function remote control is included, allowing volume adjustment and source selection from your listening position. A removable protective metal tube cage is also supplied to safeguard the valves while maintaining the amplifier's distinctive appearance.
