In creating AQs new Conductive Carbon Fibre Brush AudioQuest created new tooling for every part of the new design. AQs reborn Brush has ideal conductivity from the Carbon Fibres through the internal parts of the brush to the conductive Gold Contacts placed right where your fingers need them. AudioQuest also re-investigated what is possible with Carbon Fibres finally choosing for our new Brush a far greater quantity of new smaller fibres in order to more effectively sweep away micro-dirt not just the less relevant visible dust.
