The new Cayin Jazz 70 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.With 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.
The new Jazz 70 features selectable Triode and Ultralinear modes with handmade low-magnetic-leakage toroidal power transformer along with wide-frequency-response EI output transformers.
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 a wide range of loudspeakers.
The new Jazz 70 features Bluetooth that includes 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.
The new 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 versatility.
