About
It’s a kind of magic !
Dear friends,
welcome to the magical world of Bluetone Audio Engineering ! 
To all those who have seen and listened to our audio systems even once, surprise is the most certain feeling. And there is a reason …
It’s a world of
Stunning Beauty and Absolute Performance.
Bluetone Audio Engineering is a new and distinguished Hellenic Company committed to the Design and Construction of Innovative and Beatiful High-End Audio Systems.
Bluetone Audio Engineering was founded by Chris Fotakis (an Electronics / IT Expert) and Sophocles Harlaftis (a Dr. Mech./Electr. Engineer). The goal of the company is to create the best possible audio systems of worldclass quality, by applying – without any compromise regarding cost- crystal clear engineering design principles plus our own innovative and patented ideas. 
No other company has resolved the problem of cabin standing waves in such a radical way. The shape of the Full Pentahedron Pyramidoid with Upright Base (patent) eliminates completely all resonances due to the geometrical shape, has less vibrating modes and combines more stiffness at less weight : the loudspeaker SIRENE 60 and 1,45 m tall weighs 24,8 kg only, without it’s fin (made out of aerospace alunimum FORTAL).
The result is incredible !
Completely free and natural sound, total absence of the “box”, amazing 3D staging…
Music is breathing, sound reproduction is transformed to a live musical event.
Let’s talk about electronics. 1rst order filters for the loudspeakers, with phase correction (PHASE proprietary circuit, not Zobel). Single Ended Triode or Push Pull Triode Amplifiers : 3 X 300B power triodes per chanel in parallel - pure class A operation only – without any local or global feedback. Preamplifiers are equiped with selected E88CC/6922 double-triodes, regulated voltage at the filaments and bias, handmade -special rated- transformers. Minimalistic and original design approaches, patents, skillful construction, just a few components wisely selected from well known and absolutely top rated High End Brands. The signal path is formed by components soldered “point to point”, while regulations of filaments and bias are gathered on a military grade goldplated PCB.
There is a reason why …
