Unison Research prides itself on creating superb sounding
and beautifully made products that are praised by reviewers
throughout the globe. Being expert in both single-ended
valve and solid state amplification, the Unison Research

S6
£2395
Hailed by Hi-Fi World as “easily the best tube amplifier at
the price”, the S6 is a Class-A design that uses six EL34
power valves to create 33W per channel in triple-parallel
single ended mode. Again, offering superb value for money,
the S6 features typical build quality and styling of a
classic Unison product and features a sound full of both
refinement and authority. The S6 is supplied with a lift-up
protective grill and radio frequency volume remote control.
The preamplifier stage consists of two directly coupled
triode valves.
The output stage uses three EL 34-type valves for each
channel, connected together in triple-parallel
configuration and operating in single-ended Class-A
ultralinear mode.
The output transformer - in the Unison Research® tradition
- has been specially designed and handmade in our own
workshops. It allows a very wide frequency response
together with the highest possible sound quality.
Outputs are provided to cater for loudspeakers of both 4
and 8 Ohms.
The mains power supply transformer is of generous
proportions and will provide all the energy that may be
needed by the amplifier under all conditions of use.
During the development stage, great care was taken to
design for the absolute minimum number of components in the
audio signal path, and thereby allow a close approach to
the theoretical ideal of unimpeded signal flow.
Last but not least, all connections to both inputs and
outputs are gold plated, which will ensure excellent
electrical contact over the lifetime of the product.
S8
£4395
The S8 represents high-end, specialist valve design at an
incredibly reasonable price. It uses two legendary 845
valves (one per channel) in its pure triode output stage to
create a healthy 24W of pure single-ended power. Sound-wise
it has depth, control, transparency and supreme detail
along with delicacy. This is a design for those dedicated
music lovers who wish to glean the best possible sound
along with. value for money. The S8 comes complete with
remote control.

triode ECC83 4 x KT88
Stereo/Mono Power Amplifier
Unison Research P30K has been designed to satisfy the
demands of audiophiles who require high power together with
outstanding sonic performance. To achieve his demanding
brief, we have chosen to use four KT88 power valves in the
output stage - two per channel - configured in pure class-A
parallel single-ended mode. This provides 30 watts of power
with considerable driving ability and quite exquisite
musicality. P30K is in short, a powerful yet refined
performer.
Extra
versatility
Uniquely for an amplifier of this type, the output may be
switched externally to give 6o watts of mono power whilst
still maintaining its class-A single-ended mode of
operation. And in order to allow perfect matching with all
loudspeakers - even those with difficult impedance
characteristics - three output taps are provided ranging
from 4 Ohms to 16 Ohms for stereo configuration, and from 2
Ohms to 8 Ohms for mono configuration.

passive RIAA circuit using three twin-triode valves and is
switchable for optimal matching of both MM and MC
cartridges. The phono board is mounted on a compliant
rubber suspension to reduce microphone noise.
