This is the DNA Ultimate , yes THE ULTIMATE AUDIO/MUSIC AMPLIFIER . The ultimate has been evolving from the ONIX AUDIO Range since 1984 . Evolution &  Improvements have made it the best amplifier EVER MADE . Every single component used in the amp is measured & matched as a pair for each channel, then selected for its perfection of sound & design specification. It is then assembled by hand in the UK and tested for a month to "Break in the components " Then we measure it again to make sure its still perfect . Its made for you and you alone, it takes a long time to make . Ultimately  you pay for what you get and you get the best   . We get perfection every single time EVERY SINGLE TIME
