Cayin Jazz 70 tube integrated amplifier
17 W/8 Ω triode, 35 W/8 Ω ul · min load 4 Ω · push-pull tube · BT, DAC, headphones · current: unknown; drive: unknown; speakers ≥ 91.1 dB/W · mid
Audiomania expert verdict
A compact tube integrated on four EL34s (push-pull, class AB1) with triode/ultralinear switching (17/35 W), hand wiring and LDAC Bluetooth 5.1. For sensitive speakers in a small room and quiet, tone-rich listening; only three line inputs, so vinyl and digital need external boxes. No auditions yet — the character is from manufacturer data.

In brief
Best if you are looking for:
- two characters in one box: triode 2 × 17 W (“suppleness, tonal richness, intimacy”) and ultralinear 2 × 35 W (“dynamic reserve and control”) AI draft, under review
- sensitive speakers (≥ 90 dB/W) in rooms up to ~20 m² at moderate volume AI draft, under review
- Bluetooth 5.1 with LDAC and aptX HD through an ES9018K2M DAC — a phone as the source, no extra boxes AI draft, under review
- hand-wired point-to-point, a matched EL34 set, VU meters with bias control — classic tube construction that is easy to service AI draft, under review
- 16–300 Ω headphones from the tube output, a remote and a compact 300 mm width AI draft, under review
Keep in mind:
- only three line inputs and Bluetooth: no phono, USB, optical, HDMI, sub or pre output AI draft, under review
- 17/35 W — not for loud parties, big rooms or demanding speakers; by rule 100 dB peaks need ≥ 91 dB/W speakers AI draft, under review
- a tube amp runs hot (up to 240 W draw) and needs ventilation; tubes are consumables with periodic bias checks AI draft, under review
- 15.6 kg and 338 mm deep; no specialist comments or reviews yet — the sound character here is from manufacturer prose AI draft, under review

Technologies and construction
4 × EL34 push-pull, class AB1, triode / ultralinear
What it is: A matched EL34 quad in push-pull class AB1; mode switch: triode 2 × 17 W, ultralinear 2 × 35 W.
Practical benefit: Two characters: “suppleness, tonal richness, intimacy” or “dynamic reserve and firmer speaker control”.
3 × 12AU7 / ECC82 preamp
What it is: Three 12AU7/ECC82 tubes in the preamp; 380 mV input sensitivity, 100 kΩ input impedance.
Practical benefit: Common, inexpensive, easily replaced tubes — room for tube rolling. AI draft, under review
Hand-made toroid, EI output transformers, point-to-point wiring
What it is: A hand-made low-leakage toroidal power transformer; wide-band EI output transformers; hand point-to-point wiring.
Practical benefit: Stable power and carefully laid-out signal paths; the serviceability of classic tube construction.
Bluetooth 5.1 LDAC / aptX HD with an ES9018K2M DAC
What it is: Qualcomm QCC5125 module, LDAC, aptX HD, aptX LL, aptX, AAC, MP3, SBC; ESS ES9018K2M DAC; range up to 10 m; name “Cayin HD BT”.
Practical benefit: A phone, tablet or PC as a source “without an extra receiver” — the only digital path into this amp.
VU meters with bias control
What it is: Two meters show power and serve for setting and checking the output tubes' bias current.
Practical benefit: Tube replacement and bias trimming without external instruments — by the front-panel meters. AI draft, under review
4/8 Ω taps, 16–300 Ω headphones, remote and cage
What it is: Separate 4 and 8 Ω terminals, a 16–300 Ω headphone output, a remote, a removable metal cage; 300 mm wide, 15.6 kg.
Practical benefit: Speakers connect by nominal impedance; “the relatively small width simplifies placement”.
