Time and its cost is paid back with evolution and perfection
The ONIX DNA-50, a 100W Real RMS per channel, integrated amplifier.
Independent Vinyl stages,consumer up-gradable. DAC/Bluetooth boards to follow, with an ONIX designed and made toroidial pure path power supply. Crafted in a package formed of solid aluminum, that's AS7003 (aerospace spec).The main board is made and assembled by ONIX . The DNA 50 is the result of years of R & D and over 200 prototypes. Perfection takes time.
10KG, made of aluminum, 435mm wide, 285mm deep, and only 45mm / 2 Inches tall.
We have made the thinnest amp ever made with pure signal path technology, inside a 100% aluminum case that forms the ultimate heat-sink - removing all vents that normally cause weakness and reliability issues in any amplifier.
If the ONIX DNA-50 was made with steel instead of aluminum, it would weigh over 32KG.
Not everyone wants a huge ugly amp in their ever decreasing and demanding living spaces ( we sure don't ) .Some people want performance in a beautiful package . The ONIX DNA-50 can be enclosed or hidden anywhere and is capable of taking up to 100KG on top of the unit, ( no other integrated amp we know of can do that ) such as a large screen TV or other separates. It can be used at any angle with no compromise of function, sound or heat. It can be used in hostile environments ( Moisture heavy ) and was designed for such use, we believe no other amplifier can match our versatility and future proof life expectancy of the DNA 50. We are sadly not responsible for the music being made, or MP3 being rented from all and sundry . We say OWN the music before you lose the choice .
The DNA-50 is ultimate evolution of our classic OA21s.
Designed by one and the same person, Adam Worsfold, using knowledge gained from ONIX AUDIO , development founder of ONIX AUDIO and the classic ONIX OA21s. Creating a pure signal path with unmatched imaging ( Separation measured by Signal to noise Ratio ) of sound that time and compressed MP3 have forced so many listeners to forget. The ever slipping standards of cheap ear damaging junk sold everywhere today .
The digital world is here, at ONIX our analogue ears are NOT forgotten. Neither are yours.
Take care of your ears, bad sound and cheap products cant pay for new ears later with money "saved ". One set of ears is all we have lets look after them you will miss them when their gone.

Hifi Pig (April 2017)

"The DNA-50 amplifier has a real solidity and assuredness that you don’t even bother to seek out its purported strengths or weaknesses, you simply sit back, relax, spin your favourite tunes and be comprehensively drawn right in by the clarity, power and emotion of the music."

"The DNA-50 unveils plenty of detail and lets you know what's going on without making you think about the sound: in other words, the emphasis is on the music."
