From the original creators of the portable DAC/Amp as we know it today: Audioquest follow up with the Dragonfly Cobalt, on the back of the rave Dragonfly Black and Dragonfly Red. [See Product Desc. For More] Digital audio has moved on from the very earliest days. Cobalt comes brought up to speed with ESS Sabre's latest ES9038Q2M, MQA decoding and an adherence to minimum-phase reconstruction for the smoothest yet most detailed sound yet. Coming with its own USB-C adapter for smartphone, tablet and Apple iPad use, Audioquest have thought of everything in their most mature product yet. Please view their options here or our other DAC/Amp ones here.
