The Arkhipov’s Laboratory offers a line of exclusive, hand assembled headphone amplifiers - with a choice of valve (tube), solid-state and hybrid configurations. Our design philosophy is aimed at achieving superlative audio performance at the power levels needed by high quality headphones.«RETRO»

All our valve (tube) amplifiers use proven, classical circuit topology based on triodes or pentodes as well as combinations of both. Output transformers are hand wound and designed individually for each unit. This results in a brilliantly light, lively and open sounding amplifier having excellent dynamic range suitable for reproduction of all types of music - from the lightest instrumental and vocals to hard driving rock, electronic or jazz.«ULTRA NOVAL»

The transistor and hybrid models are designed and made with the same perfectionist approach as our all-valve (tube) units.

The proof of our designs lies in the very low level of listener fatigue - even after extended periods of listening.

FEATURES

Arkhipov amplifiers cater for a wide range of headphone impedances from 20 to 600 Ohms. Some models accept loads down to 8 Ohms. Each unit has dual outputs using two standard 1/4" (6.35mm) jacks.

Signal source for our amplifiers is line-level of 250mV rms or higher, from CD players, phono preamps, computer sound cards etc. «ULTRA DUAL EL»

An additional & very useful application is as a high-performance buffer-amplifier between a signal source & consumer-grade power amplifier driving speakers. You will be pleasantly surprised by the improvement in sonic quality that is possible with such a configuration.

The designer and constructor of these high grade amplifiers, Alexandr Arkhipov, is a highly qualified electronics engineer with decades of professional design experience in this field. His expertise guarantees first-class quality and finish of all his products.

Arkhipov amplifiers are constructed by hand in laboratory conditions. Metal chassis parts are professionally fabricated with a high-grade black powder-coat finish. The timber plinths are entirely made from solid timber with a choice of oak, cherry, plum or other quality woods. All timber parts are coated with a hard-wearing, satin lacquer finish.

Wiring is point-to-point with teflon insulation used exclusively and all components are of the highest quality. Each unit is subject to rigorous inspection & testing during each stage of construction, and additionally, undergoes a week-long proving cycle including burn-in, performance & listening tests.

Not all versions of the Akhipov range are shown on this site, because the designs are subject to constant upgrading & improvement as well as often being custom-made to order. But all our amps carry a lifetime warranty (with the exception of valves (tubes).
