Integrated amplifiers — Cayin Jazz 70

The Jazz 70 is a tube integrated amplifier from Cayin, sitting above the CS-55A with considerably greater output power in both operating modes. The Jazz 70 brings Cayin's most storied engineering heritage to a substantial tube integrated chassis with genuine sonic-character flexibility.

Key specs that matter

Three single-ended inputs are provided. Input sensitivity is 380mV, with input impedance at 100,000 ohms single-ended, matching the CS-55A. Output power is 2 x 17W in Triode mode or 2 x 35W in Ultralinear mode - considerably more than the CS-55A's 20W/38W single-figure specification. Frequency response spans a wide 8Hz to 60,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 100dB, with total harmonic distortion plus noise at 0.2%. At 300 x 338 x 190mm and 15.5kg, the Jazz 70 represents a substantial commitment reflecting Cayin's most storied tube-informed engineering heritage.

Sound and use context

Expect the warm, richly textured character tube amplification is broadly celebrated for, with the distinctive Triode/Ultralinear selectability offering the listener a choice between a more characterful triode signature and greater power.

Pairing

The selectable Triode/Ultralinear operation lets the listener choose the sonic character to match different loudspeakers or moods.

Alternatives

Cayin's own CS-55A offers a more compact, accessible alternative within the same broader integrated amplifier catalogue.
