From the atelier
Hades combines a Demograf Audio DAC and a Class D power amplifier in one compact chassis. The output transistors are switched by a dedicated PWM chip and a custom output choke filters the switching carrier, so the amplifier turns power into sound rather than heat. Stock output is 70 W per channel, and it can be built up to 1 kW — enough for demanding dynamic and planar headphones and full-size loudspeakers. A hybrid version with a 6Zh4 or EF55 tube input stage is available.
Custom in-house transformers, and capacitors from Jamicon, Nichicon, Nippon, Epcos, Vishay and Mundorf.

Pairs well with
Does the Hades use tubes?
Hades is solid-state as standard. The hybrid versions use a 6Zh4 or EF55 tube in the input stage.
How is the Hades serviced?
Each unit ships with its own measurement report. The circuit is kept simple and serviceable, and Demograf Audio gear is serviced for as long as parts exist.
How is it delivered?
Shipping and insurance are paid by the buyer and shown as a separate line in your quotation. Every unit is packed for long-distance transport in heavy-duty flight cases and a wooden crate.
Which mains voltage and plug?
Each piece of gear is built for 100 V, 120 V or 230 V mains with the matching plug (NEMA, Schuko or BS 1363 / type G). The voltage is fixed at order time, so tell us where the unit will be used.
How long does the Hades take to build?
Build time is six months or more from the queue deposit, depending on the configuration and the queue; delivery takes from one month after completion. The atelier builds seven instruments a year. A priority build is available for an extra 50% of the price: your unit is moved ahead in the build queue.
* Photos are taken from real systems and show the specific configuration of a particular customer; your unit can look the way you want — all our equipment is fully customisable.
