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”.

FAQ

›What is the difference between triode and ultralinear modes, and which to pick?
Maker: triode (2 × 17 W) — “suppleness, tonal richness, intimacy”; ultralinear (2 × 35 W) — “more dynamic reserve and firmer speaker control”. In practice: triode for quiet vocal/acoustic listening with sensitive speakers; UL for dense music, higher volume and less sensitive speakers. Switch and compare — it is a stock feature. AI draft, under review
›Which speakers suit 17/35 W?
By rule §4.9.17 (100 dB peaks at 3 m, 3 dB headroom): ultralinear needs ≥ 91 dB/W sensitivity, triode ≥ 94; for quiet listening (90 dB peaks) 81/84 dB/W suffice. In the catalogue the Radiotehnika Sigma 1.02 (91 dB, 6 Ω) fits these numbers. Favour sensitive speakers with a benign impedance and use the matching tap.
›Which tap — 4 or 8 Ω — should I use?
Use the tap equal to the speakers' nominal impedance: 8 Ω → 8 Ω terminals, 4 Ω → 4 Ω. For 6 Ω speakers try both and keep the tighter one (4 Ω usually gives more control, 8 Ω more power). Never run the amp without a load. AI draft, under review
›Can I stream Yandex Music?
Yes, from a phone over Bluetooth 5.1: LDAC and aptX HD (best from Android), AAC (iPhone); the DAC is an ESS ES9018K2M, range up to 10 m, device name “Cayin HD BT”. No network or Wi-Fi.
›Which headphones can I use?
The output is rated for 16–300 Ω headphones (per the table). Planar and 600 Ω models fall outside the stated range.
›Is there a phono stage?
No — only three RCA line inputs. Vinyl needs an external phono stage (e.g. Radiotehnika PH001) or a turntable with a built-in one.
›How do I connect a TV or PC?
There are no digital inputs: TV and PC go through an external DAC with RCA outputs into a line input, or over Bluetooth if the source transmits it.
›Does it run hot, and is the cage needed?
Four EL34s and up to 240 W draw — it runs hot: open shelf, headroom, never cover. The removable metal cage in the box protects the tubes from touch (children, pets); remove it at your discretion. AI draft, under review
›What are the meters for, and how are tubes replaced?
The meters show power and serve “to set and check the output tubes' bias current”. The EL34s come as a matched set; when replacing, buy a matched quad and set bias by the meters per the manual.
›Can I connect a centre channel?
No: a stereo amplifier drives two channels; multichannel cinema needs an AV receiver.
