After over 35 years of work in the field of High End Audio, from the design and manufacturing of entire playback systems to the recording of over 300 acoustic concerts to gain further musical insights, the last thing that artist-designer Kostas Metaxas wanted to produce was “another set of boxes with transistors on a heatsink”.


Kostas was dreaming of the most spectacular architecture, design and sculpture he had experienced and wanted to bring that emotional intensity, daring and seductive beauty to audio amplifiers. 


As a recording engineer, Metaxas also wanted to “voice” them for extremely realistic recording playback, to be able to reproduce all the nuance and emotion of a musical performance.


His new IKARUS, SOLITAIRE and SOLILOQUY amplifiers are the result. Machined from a solid block of either aircraft aluminium, copper or titanium, they're totally bespoke and the modular electronics make them future-proof. Even the circuit boards can be CNC machined from 1mm solid silver coated clear polystyrene.


From the sensual, organic and striking casework [inspired by the stunning work in Sports cars of the 1950’s/60’s of Ercole Spada, as well as the architecture of Hadid, Gehry and Calatrava] to absolutely every part of the amplifiers including the circuit, topology, layout and casework have been developed by Kostas Metaxas. It is the logical evolution of his ground-breaking design concepts pioneered in the early 1980’s.


Then, it true “Bugatti fashion”, each and every amplifier is assembled by the master or his sins — either Andreas or Alessandros Metaxas.


The individually 5-axis CNC’d “sculptural” enclosure presents a very heavy, solid, inert, non-resonant structure to RFI shield and ultimately protect the delicate electronic signals, driving the noise floor to ultra-ultra-low levels, revealing a wealth of detail that has never been heard before.

Soliloquy Mono-block power amplifiers

Each Soliloquy channel is made up of essentially five complete amplifier circuits, encompassing the linear gain input stage with high current output stage and four amplifier circuits whose role is to supply an absolutely stable voltage and current source irrespective of A.C. line condition.

The U.H.F. and R. F. circuit board techniques have been essential to ensure that the amplifier is unconditionally stable into any known loudspeaker load, including inductive electrostatics or low impedance ribbons.


Each mono-block amplifier features two massive 800W mumetal toroidal transformers and a separate 200W mumetal toroidal to ensure that the high current output stage does not affect the low current input stage. All connectors are of the highest quality, and every component, including the 40,000uF computer grade capacitors are directly connected to the printed circuit “high-current” board or separate “future-proof” input voltage amplifier/discrete voltage regulator board for ease of servicing and to maintain the shortest possible signal path.

 

So neutral though, is the Metaxas Opulence/Soliloquy set up that I could have used just about any sources I liked once the interconnecting cables were sorted. All I’d be hearing were the individual characteristics of the source components. However neutral or ‘naked’ the sound, the MAS doesn’t come off as ‘transistory’ or clinical... it had a feather-light touch and a way with tiny details that suggest either a pedigreed 60W or 70W per channel tube amp of recent vintage...

KEN KESSLER, HI-FI NEWS& RECORD REVIEW, ENGLAND.

It would make a perfect tool to assess equipment by. If any component is not in the top league, the amps will betray the culprit with surprising honesty. Its other great strength is the speed of delivery. It can keep up with the fastest of guitar runs and tabla rolls with a speed normally associated with single-ended valve amplifiers.
