Neodio CD players, amplifiers, cables







“…the detail of dCS, the naturalness of Wadia, the stage-width of an Esoteric and the bounce of Naim. It manages to mix the best of these without sacrificing the whole.”


“A strange aspect of the NR22 that is also common on good vinyl – but rare on CD – is its ability to change tonality with each new disc.” “…but most CD players blur this distinction.”


“The NR22 is a world class player that can do both (play CD and process Hi-Rez files via USB) well”


- excerpts from HiFi+ Issue 76 review



“NeoDio keeps impressing me on the tonal color and bass elasticity resembling much of my Da Vinci LP setup….I have not heard a better source playing vocal, violin and cello!! The realism just thrills me up!!”

“I would not spend the time to tell you all the scores by attributes if my "gang" over here was not "floored" by it. It (Neodio) eclipses the Zanden 2000p/5000s by a wide margin, as musicality seems to be newly discovered from the same records over and over."


“This Neodio NR22 CD player from France could well be the best CD player ever made. The dynamics and vibrancy of the whole frequency range eclipsed the goldmund by a planet. The vinyl-like density is shocking. We thought we need to compare again. But not necessary, it just stay on my rack now.”

"My passion for good sound comes from youth. At this time, I discovered the Hi-Fi my dad had just bought. My interest for this field grew up with the reading of specialized newspapers, and a visit to the Sound Festival in Paris.


As I was student engineer in electronics, one of my teachers gave me the whole articles of Hephaistos (Lavardin designer), published in the newspaper named L'Audiophile.


My passion focused on electronic circuits. I was shocked by the elegance and the complexity of circuits described by the author.


Engaged by Schneider Electric, I designed sensors for 12 years. An exciting job where I used my knowledge in audio electronics to improve my skills in analog circuitry.


The understanding and the right use of the transistor became one of my specialities.


In 1988, I made my first amplifier. It had two peculiarities: no global feedback (it's still the case for Neodio) and a systematic cascading of all the transistors ( a technique used in high frequencies or in oscilloscopes).


Since then, in parallel with my job, I kept improving my amplifier circuits for pleasure.


At that time I made my first disconcerting experiences: circuits never behave sonically like they should do , and the results depended a lot on details that were thought to be sonically harmless.


My meeting with the researcher Pierre JOHANNET warned me about the existence of physical phenomenon modifying sound quality in hi-fi reproduction.


In 2001, I created my company, Seven Audio, to develop my own device range, named Neodio. Today, an important part of the turnover is invested in research.

We try, through experiences, to build physical models for all the phenomenon modifying the quality of the sound."

Neodio ... Industrial Design



Neodio products have an outstanding manufacturing quality.

With his experience at Schneider Electric, Stephané Even has developed high quality circuit boards using only reliable and lasting industrial parts from professional applications.



These parts are mainly soldered with an automatic process by a sub-contractor working for medical and aeronautics fields.


Lots of calculations and test were done to optimise the dimensioning of components. This allows to use them with a high margin, guaranteeing a maximum lifetime.



Neodio Board



The whole range of products present the following features :

• Non magnetic aluminium and wood chassis.
• Gold plated circuit boards
• Specific oversized toroidal transformers
• Systematic use of industrial high reliability components (no exotic audiophile components)
• All electrolytic capacitors are of 105°C grade which guarantees the highest reliability
• Volume and balance adjusted by integrated circuit :64 steps of 1 dB (amps)
• Digital display
• Friendly remote control
• Gold plated connectors
• Chassis engineered to reduce the impact of vibrations
• Semi-floating feet
