The new top model is equipped with the ES9038Q2M converter chip and a particularly power-saving and even faster micro-controller than the "Red". In addition, the supply voltage should be better protected against interference from WLAN, Bluetooth or mobile radio. The "Cobalt" is even 5 millimeters shorter than the "Red". With its 2.1 Volt output voltage, it can power most headphones directly. The volume is set lossless on the digital level. Like the other two models, the DAC can handle resolutions up to 24 bit / 96 kHz and acts as an MQA renderer. The stick can be operated directly on computers with a USB-A port - an adapter for USB-A is included for smartphones or laptops with a USB-C socket. Apple devices with a Lightning port must be connected via Apple's "Lightning to USB Camera Adapter".
