Audioquest Dragonfly Cobalt is the mightiest one so far

So what exactly makes Cobalt the best Dragonfly yet?

• New, more advanced ESS ES9038Q2M DAC chip with a minimum-phase slow roll-off filter for more natural sound.
• Microchip’s superb PIC32MX274 microprocessor draws less current and increases processing speed by 33%.
• Improved power-supply filtering that specifically increases immunity to WiFi, Bluetooth, and cellular noise.
• Includes a form-fitting DragonTail female USB-A to male USB-C Adaptor.
  All DragonTails use AQ’s Carbon-level USB cable.
