Awards & Innovations
01
2 X AUSTRALIAN EXPORT AWARD, BHP STEEL DESIGN AWARD,
runner up in AUSTRALIAN SMALL BUSINESS AWARDS
First - Amplifiers- No wire construction with
shortest possible signal path
First - 'Capacitorless' circuits in Audio design
First power amplifier can put full power into
8 ohm load at 1.0MegaHertz!
(refer to article in USA "AUDIO").
First - High Speed diodes in power supply
First - DAC to use lowest jitter 'APOGEE CLOCK'
First - FULL range and high efficiency electrostatic
First - Audio Manufacturer to use BMW-Porsche CAD-PCB
software design systems
You are about to listen to
an amplifier which has
evolved from over 20 years
of dedicated listening and
the application of the
state-of-the-art in every
process of design and
manufacture. I’m sure
you’ll enjoy listening to it
as much as I do.

Using technology borrowed from Aerospace and Formula 1, the new
Kostas Metaxas Audio designs reflect the extraordinary
advances that have been made recently in modelling and simulation
software.
For the first time, a High End Audio manufacturer offers audiophiles a
rare glimpse into the conception, design and execution of a complete
product on a component by component basis in 3D.
The Protel PCB software [www.protel.com] extends the quite normal
listening tests on a component by component level to the PCB level.
Schematic Based simulations can test [or verify] the PCB's signal integrity
by running the "Signal Integrity Simulator" which displays a Reflection and
Crosstalk Analysis. And the 3D visualization allows one to include the PCB
as part of the overall wholistic design.

Listening Philosophy
05
The only way to design state-of-the-art audio equipment is to have
first-hand experience with the finest available recording equipment AND
playback equipment.
This is important for two reasons; it ensures that our designs work and
'mate-well' with other products and that their resolution is not limited
by the weakest link in the playback 'chain'.
Kostas Metaxas products have been conceived using
extensive listening tests with a variety of state-of-the-art ancillary
equipment for more than 25 years.
Our amplifiers have been designed using a variety of state-of-the-art
phono playback equipment and our ABSOLUTE REFERENCE a custom-made battery-powered Stellavox SM-8 Tape Recorder using
1/4" tape at 30 ips and a Stellavox TD-9 using 1/2" tape at 30 ips
specially calibrated for the Bruel & Kjaer 4003 1/4" omnidirectional
electrostatic instrumentation microphones.
