Cayin Puts Four EL34s at the Bottom of the Jazz Range with the $1,399 Jazz 70

Cayin has added a new entry point to its Jazz range with the Jazz 70, a Class AB1 push-pull integrated amplifier built around four matched EL34 output valves. It has been announced at US$1,399, EUR 1,598 and A$2,999 — three separately quoted regional prices — and it slots beneath three larger Jazz models that use KT88 and 805A output stages.

The headline of the design is straightforward enough: a cheaper, very widely available output valve at the foot of an existing valve range. But the more interesting detail is what Cayin has chosen to put around it. The Jazz 70 carries a headphone socket and Bluetooth, and it does not carry a single wired digital input.

Power and valve complement

The Jazz 70 is rated at 35 watts per channel in ultralinear mode and 17 watts per channel in triode mode, with the mode switchable by the user. That is the usual arrangement for a push-pull EL34 amplifier of this kind: roughly half the power in triode, with the same output valves doing the work either way.

Four matched EL34s handle output duties. The preamplifier stage uses three 12AU7 valves — the type is also catalogued as ECC82 — which makes for a seven-valve complement in total. Cayin quotes dimensions of 300mm wide, 338mm deep and 190mm high, and a weight of 15.6kg. Two finishes are listed, a black or a silver front panel.

Inputs: three RCA pairs, and Bluetooth

This is where the Jazz 70 diverges from what a lot of buyers now expect at the price. There are three RCA line-level inputs. That is the extent of the wired connectivity for sources.

There is no USB input, no optical, no coaxial and no HDMI. There is no Wi-Fi, and there is no built-in phono stage. The only digital path into the amplifier is wireless: Bluetooth 5.1, implemented on a Qualcomm QCC5125 chipset and feeding an ESS ES9018K2M DAC. Codec support is broad — LDAC, aptX HD, aptX Low Latency, aptX, AAC and SBC are all listed.

It is worth stating plainly, because it shapes how the amplifier can be used. A listener with a CD player, a tuner or an outboard DAC has three line inputs to work with and no shortage of room. A listener who wants to run a laptop or a streamer over a cable, or plug in a turntable without buying a separate phono preamplifier, will need to add a box. Anyone feeding it from a phone or tablet, meanwhile, gets a fairly complete Bluetooth implementation, including LDAC and the aptX family, rather than SBC-and-AAC only.

Whether that is the right set of compromises depends entirely on what a given system already contains — and it is a set of compromises rather than an oversight, since Cayin has clearly spent the connectivity budget on wireless and headphones instead of on wired digital.

A headphone output on a valve integrated

The Jazz 70 includes a 6.35mm headphone output, rated for loads from 16 to 300 ohms. That range covers a lot of what people actually own, from low-impedance portables at the bottom end to the 250- and 300-ohm dynamic studio and audiophile designs that traditionally want a bit of voltage behind them. Cayin publishes no separate power figure for the headphone stage in the material available here.

Combined with the Bluetooth receiver, the headphone socket points at a particular kind of use: a compact valve amplifier that can be driven from a phone and listened to on headphones as easily as through speakers, without a second component in the chain.

Where it sits in the Jazz range

The Jazz 70 is the smallest and least expensive Jazz model. Above it are three larger amplifiers in the same family, using KT88 and 805A output stages. StereoNET's framing of the launch is that the EL34 design gives the range a more accessible entry point, which is a fair reading of what has happened here: rather than building a new budget line, Cayin has extended an existing one downwards by changing the output valve.

What that means for the sound of the thing is an open question, and one nobody has answered yet. No listening impressions have been published for the Jazz 70 in any of the coverage available at the time of writing, and there is no basis on which to say how it compares with the KT88 and 805A models sitting above it. Likewise, Cayin has not published distortion, frequency response, damping factor or signal-to-noise figures for the amplifier, so the specification sheet is a shorter document than it might be.

Prices as announced

• United States: US$1,399
• Europe: EUR 1,598
• Australia: A$2,999

Those are the three figures as announced for their respective regions, and they are not conversions of one another. No shipping date has been established by any of the sources covering the launch, and no dealer or distributor arrangements have been detailed.

The short version

The Jazz 70 is a 35-watt (ultralinear) / 17-watt (triode) push-pull EL34 integrated with a 12AU7 front end, three line inputs, a 6.35mm headphone output and Bluetooth 5.1 with LDAC and aptX HD support — and no wired digital input of any kind. It is the cheapest way into Cayin's Jazz range, and the specification makes clear what has been traded to get there. What it does with music remains to be heard.
