Headphone amp

Ethereal

“Imagine a true ultra-high-end system using the finest headphones ever made - electrostatic headphones, ”
— which rivals large physical hi fi systems at upwards of over USD$1M

“at a fraction of their cost...but which also is a desirable objet d'art.

This is the "Ethereal System".

FEATURES

Ethereal

No stranger to creating objects which never existed before, artist/engineer Kostas Metaxas has also managed to marry a Swiss Tourbillon [LePee] clock and offer it as a beautiful abstract moulage mannequin. Like all Metaxas & Sins amplifiers, the CNC-machined “Ethereal” can be meticulously finished in a choice of 10 aluminum colours, or automotive painted finishes.

The CNC's casework also features one of Kostas' patternation called "Geometrika" which creates a visual patina of squares and rectangles recessed into an organic shape - requiring the most advanced 5-axis CNC machine to create it. Other patternations will be offered similar to those used in Kostas' Haute Creation work for S.T. Dupont of Paris.

The solid CNC-machined base encloses the power supply to keep all stray RFI and noise from the delicate low-level signal stages.

FEATURES

PAPPILION

Inside the case are two entirely mono ultra-low-noise high voltage purely discrete and utterly balanced amplifiers dedicated to electrostatic headphones running at over 1000V peak-peak.

The Bias voltage of 580V [standard for STAX, SENHEISSER and most electrostatic headphones] is absolutely ripple-free and running at high frequencies to avoid any interference with the delicate audio signals.

The head section can be offered as a "stand" to support the headphones when they aren't in use, or in different configurations including a Tourbillon Clock version, a DAC [Digital to Analogue Converter] or in the near future, a full digital music streamer.

Ethereal

“Listened to the SR-X9000 driven by the Metaxas & Sins headphone amp in Florida last weekend. Hans down the best I've ever heard the SR-X9000. I would even go as far as to say it was one of the best sounds I've ever heard in my life.”

I got the listen to the amp through a pair of Stax SR-X9000 headphones and immediately acknowledged the fidelity of the system. It was truly astonishing. With some of the most intricate and stylish designs of any HiFi equipment I have ever seen, these items really make a statement.
