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

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:

speaker transformers on EI core

Khozmo 64-step attenuator with
IR remote control

Nichicon, WIMA, Jantzen Superior

Top quality PCBs made in Poland

ceramic vacuum tube sockets

WBT speaker terminals and Neutrik
input sockets

metering socket for setting BIAS for power vacuum

Omron high quality source selector relays

The power supply uses:

two toroidal TELTO

Nichicon electrolytic capacitors

filtered mains socket

Amphenol military 10-pin output

Connection of the power supply to the amplifier is
realized with a cable line in military technology of Raychem.

voltage was separated from DC voltage by screening and cable

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.

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

Our amplifier is addressed to connoisseurs of excellent
sound and top craftsmanship.
