Where the sound is decided
Dmitriy Gubchenko designs and voices the circuits in his own listening room — against the same vintage sources, directly heated triodes, horn and wide-band loudspeakers and electrostatic headphones he lives with.
An atelier, not a workshop
Demograf Audio units are built to order. Current lead time is 6 months or longer, depending on the model. Every unit is made in Kazakhstan by Dmitriy Gubchenko. Shipping and insurance are paid by the buyer and shown as a separate line in your quotation. A 50% deposit reserves your place in the build queue.
Two places, one standard of gear
Made by Dmitriy Gubchenko.
Where the gear is made
Units are assembled, tuned, measured and tested in Kazakhstan by Dmitriy Gubchenko and his team, who oversee the process in the workshop. Transformers are wound on the bench and wiring is point to point.
How to commission your gear
Built to order. Nothing on the shelf.
-
Write about your room, your music and the system the gear will join. Every inquiry is answered by the Demograf Audio team; technical questions go to Dmitriy himself.
-
Circuit, tubes, chassis, finish and mains voltage are agreed in writing. You receive a quotation and a place in the build queue.
-
A 50% deposit reserves your place in the queue; the build starts when your slot comes up, and we tell you the date. Transformers are wound, the chassis is made and the circuit is wired by hand: 6 months or longer, depending on the model.
-
The finished unit is measured and listened to before shipping. You receive its individual measurement report; the balance is due only then.
-
Shipping and insurance are paid by the buyer and shown as a separate line in your quotation. The unit travels in heavy-duty flight cases and a wooden crate, with the documentation for your unit. System matching and set-up are arranged where needed.
On the bench
Seven pieces of gear a year — and the time each one takes
The chassis woods
Seven woods, from the Caucasus to the Tian Shan
Around the tubes and transformers of many of our pieces is a wooden chassis. Our journal follows the seven woods we work with to where they grow: the timber each one gives, and what a wooden chassis can and cannot do for the sound.
- Fergana cherry Prunus tianschanica
- Transcaucasian beech Fagus orientalis
- Tian Shan maple Acer semenovii
- Charyn ash Fraxinus sogdiana
- Semirechye oak Quercus pedunculata
- Alatau walnut Juglans regia
- Kirghiz birch Betula kirghisorum
After the bench
We stay with every unit we build
One-year warranty
Every piece of gear carries a one-year warranty (extra warranty available: +1 or +2 years) and its own measurement report.
Insured worldwide shipping, quoted separately
Shipping and insurance are paid by the buyer and shown as a separate line in your quotation. The unit travels in heavy-duty flight cases and a wooden crate. Mains voltage and plug are configured at order time, so the unit is ready for your country on arrival.
Service from its own records
Serviced by the team that built it. Owners can upgrade or re-voice what they already own, and trade a unit up when their system moves on.
Documents & logistics
The paperwork that travels with your unit
How Demograf Audio states origin: a Manufacturing Record, a bill of materials, a NOS tube declaration and a measurement report with every unit.
Compliance documents
Declarations of conformity and safety test reports are issued per batch and supplied with your gear on request. We do not display certification marks (CE, FCC, CCC and similar) on this website until the corresponding tests are completed for the exact configuration you receive.
The document package for your unit
- Manufacturing Record stating the country of origin of your unit
- BOM listing the origin of key components (tubes, converters, transformers)
- NOS tube declaration: manufacturer, country and production year of each tube
- The measurement report of your individual unit
Sales & logistics
Orders are placed through our inquiry form or by e-mail, and we send you an invoice for the deposit. Shipping and insurance are paid by the buyer and shown as a separate line in your quotation. The gear travels in heavy-duty flight cases and a wooden crate; mains voltage and plug type are configured at order time.
If you require origin documentation for import purposes, write to us — we provide the paperwork that matches the facts.
