Dual Mono Class-A Headphone Amp from Erzetich Audio

You likely haven't heard of Erzetich Audio; a boutique manufacturer from Slovenia specialising in personal audio, specifically headphone amplifiers and accessories.

Blaž Erzetič, CEO of Erzetich Audio was just 16 years old when he constructed his first audiophile amplification system. A solid state RIAA preamplifier, a valve preamplifier and 2 x 100 W power amplifier working between class A and AB. Erzetič proudly tells us that 23 years later, it still works.

Located in the west of Slovenia, in the woods of Trnovo not too far away from the border with Italy, Erzetich Audio designs and manufactures products that keep a clean and fine industrial design.

The latest creation is the Deimos, a prestige dual mono class-A headphone amplifier. Despite the rough, 19th century industrial look, with an aged linden wood faceplate and milled thick aluminum parts, there's apparently a gentle soul inside. This amplifier weighing in at 6.5kgs, “sounds balanced and precise and makes an important visual statement on your desk” and was reportedley a great success among visitors at the Munich High End Hi-Fi show earlier this year.

Erzetich plans only a very limited yearly production of this completely hand crafted, prestige headphone amplifier, dedicated to the ones that can appreciate exclusive high-end audio components.


  • Chassis: steel, aluminum, wood, acrylic
  • Type: dual mono with three separate power supplies – one for each channel plus one for the digital part (advantage: complete separation of power supplies to avoid inter-channel interference or interference from the digital part)
  • Analog technology: class-A (advantage: very fast and precise amplifier technology)
  • Smoothing capacitors: 43000 uF per channel (advantage: very stable power supply)
  • Frequency response: 4 Hz-40 kHz (-1 dB)
  • Volume adjustment: digitally controlled relay based, 64 steps (advantage: complete channel separation and controlled logarithmic scale)
  • Input: RCA and XLR (advantage: selection for the most appropriate signal transfer from the sound source)

The Deimos is available for pre-order now 2999 EUR until December 31st, 2014 with free worldwide shipping.
