Super Sound Device company was founded in 2016 as a result of joining forces by two constructors from Poland, Robert Łachniak and Michał Wiktorko. Our purpose is to build Hi-End vacuum tubes amplifiers.

We introduce our first integrated dual-mono vacuum tubes amplifier based on a modernized Williamson circuit. It is a 27 Watt per channel Push-Pull, operating in ultra-linear mode, optionally switchable to triode mode.
Soviet triodes 6N8S are used as steering vacuum tubes at the pre-amplifier stage. The power stage operates on excellent GU-50 transmitter tubes, Soviet-made for the military in the 1960s (NOS).

In order to minimize distortion, the power supply is separated from the amplifying section by placing it in a completely separate, screened case.
While designing the circuit we managed to achieve identical topography of the left and right channels, which resulted in a fully symmetrical signal path.
It should be noted that volume control does not employ a common potentiometer, but a 64-step attenuator (based on relay switches) by Khozmo Acoustic, which minimizes signal inequalities in both channels of the amplifier. The circuit employs a small number of capacitors in the signal path, which also improves sound quality.

The amplifier uses only top quality components:
Ogonowski speaker transformers on EI core
Khozmo 64-step attenuator with IR remote control
Nichicon, WIMA, Jantzen Superior capacitors
Top quality PCBs made in Poland
gold-plated ceramic vacuum tube sockets
WBT speaker terminals and Neutrik input sockets
metering socket for setting BIAS for power vacuum tubes
Omron high quality source selector relays

The power supply uses:
two toroidal TELTO transformers
Nichicon electrolytic capacitors
Schurter filtered mains socket
Amphenol military 10-pin output socket
Connection of the power supply to the amplifier is realized with a cable line in military technology of Raychem.
AC voltage was separated from DC voltage by screening and cable twisting.

All the technical solutions and components used in this construction met or exceeded our expectations. We achieved superb sound with wide and deep sound stage with high separation, sweet vocals, deep bass and detailed higher frequencies.
Listening to recordings of Diana Krall or Karen Souza feels just as if the singer was standing right in front of us.

The case presented in pictures is made of steel and natural stone veneer.
Chassis is made of stainless steel in ONC laser technology. Knobs and vacuum tube rings were also turned from stainless steel.
It means excellent materials, top labor, no half measures and no expenses spared.
Our amplifier is addressed to connoisseurs of excellent sound and top craftsmanship.
