The Jazz 70 is an integrated amplifier by Cayin that delivers 35 watts x 2 channels in ultralinear mode and 17 watts x 2 channels in triode mode, Class AB1 push-pull, with 4 and 8 ohm speaker outputs. Cayin rates distortion at under 5 percent at full power.. It was released in August 2026. It is a 2-channel design using a Class A/B output stage. The Jazz 70 is an all-valve design, running 4x EL34 output, 3x 12AU7 / ECC82 input. Speakers connect via binding posts. Its output transformer offers 4 / 8 ohm taps, and matching the tap to your speaker's impedance matters more here than a minimum-load figure would on a solid-state amplifier. It has a built-in DAC (ESS ES9018K2M), so you can play digital sources directly with no separate DAC unit needed. The Cayin Jazz 70 has an MSRP of $1,399.
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Cayin Jazz 70 is rated at 35 watts RMS into 8-ohms. Cayin provides this wattage at a THD (Total Harmonic Distortion) of 0.2% at 1 W / 1 kHz, under 5% at rated power which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 35 watts into 8-ohms (8 Hz-60 kHz) at 0.2% at 1 W / 1 kHz, under 5% at rated power
- 35 watts into 4-ohms
- 4 / 8 ohm output transformer taps - match the tap to your speaker's impedance
- 100dB Signal to Noise Ratio

Which speakers suit the Cayin Jazz 70?
35 W into 8 ohms, 35 W into 4.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Cayin Jazz 70 is rated at 35 watts into 8 ohms, which puts it in our Up to 60 watts band. The next band up is 61 to 90 watts, which is worth about 3.9dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room.
When pairing the Cayin Jazz 70 with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.

Cayin Jazz 70 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓A valve design running 4x EL34, which is the point of buying one.
- ✓Signal-to-noise ratio of 100dB, so the amplifier itself should be inaudible between tracks.
- ✓Built-in DAC, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Bluetooth (version 5.1 and LDAC, aptX HD, aptX LL, aptX, AAC, MP3, SBC) for playing straight from a phone.
- ✓Headphone output.
- ✓Has VU meters.
- ✓At 300mm wide it fits where a full-size component will not.
- ✗Output rises only from 35 to 35 watts when the load halves to 4 ohms, so it is happier with an easy 8 ohm speaker than a demanding one.
- ✗Valves are consumables: they need replacing periodically, and often biasing, which a solid-state amplifier never asks of you.

How much power does the Cayin Jazz 70 have?
The Cayin Jazz 70 delivers 35 watts x 2 channels in ultralinear mode and 17 watts x 2 channels in triode mode, Class AB1 push-pull, with 4 and 8 ohm speaker outputs. Cayin rates distortion at under 5 percent at full power..
Does the Cayin Jazz 70 use vacuum tubes?
Yes. The Cayin Jazz 70 is an all-valve amplifier: vacuum tubes do the amplifying from input to output. It runs 4x EL34 output, 3x 12AU7 / ECC82 input.
How long do the tubes in the Cayin Jazz 70 last?
Output valves are a consumable. In normal domestic use a set lasts somewhere between about 2,000 and 5,000 hours - a few years for most people - and they degrade gradually rather than failing outright. Input and driver valves last far longer, often the life of the amplifier. Check the warranty card before you buy: valves are almost never covered by the amplifier's own parts warranty, and are usually warranted separately for 90 days to a year.
What speakers suit the Cayin Jazz 70?
A valve amplifier is judged on the speaker's sensitivity, not just on watts. At 35 watts, the safe rule of thumb is a speaker of about 90 dB or better - an insensitive speaker will run out of headroom long before the amplifier sounds bad. It also has 4 / 8 ohm output transformer taps. A valve amplifier has no minimum impedance the way a transistor amplifier does; you match the tap to the speaker, and a speaker whose impedance swings a long way will shift the tonal balance slightly because a valve amplifier follows that curve.
What amplifier class is the Cayin Jazz 70?
The Cayin Jazz 70 uses a Class A/B amplifier design. Class A/B is the traditional linear design: it runs warmer and is less efficient than Class D, but it is long valued for its natural, low-distortion sound.
Does the Cayin Jazz 70 have a built-in DAC?
Yes. The Cayin Jazz 70 has a built-in DAC (ESS ES9018K2M), so you can feed it a digital source directly without buying a separate converter.
Can I connect a turntable to the Cayin Jazz 70?
No. The Cayin Jazz 70 has no phono input, so a turntable needs an external phono preamp (or a deck with one built in) before it can be connected.
Does the Cayin Jazz 70 have Bluetooth?
Yes. The Cayin Jazz 70 supports Bluetooth (Bluetooth 5.1 and the LDAC, aptX HD, aptX LL, aptX, AAC, MP3, SBC codec), so you can stream straight from a phone, tablet or laptop.
Does the Cayin Jazz 70 have a headphone output?
Yes. The Cayin Jazz 70 has a Yes-inch headphone output on the front panel for private listening.
How much does the Cayin Jazz 70 cost?
The Cayin Jazz 70 has a manufacturer's list price (MSRP) of $1,399.
