iBasso DC07PRO (black)

The DC07PRO is a USB-C DAC and headphone amplifier small enough to hang from a phone cable. Inside are four Cirrus Logic CS43131 DACs and iBasso's own FPGA, which generates low-jitter clocks for the DAC and USB receiver so timing errors from the USB bus are reduced; it decodes PCM up to 768 kHz/32-bit and DSD512. iBasso states a THD+N of 0.000098% and an efficient DC-DC converter that draws only about 80 mA, 40% less than the older DC04PRO, while giving 82% more output power. A 0.96-inch OLED screen and an ALPS rotary encoder let you change volume and settings on the device, and Android users can also use iBasso's app. It has balanced 4.4 mm and 3.5 mm headphone outputs and can send S/PDIF up to 768 kHz/32-bit to an external DAC. The body is CNC-machined aluminium with a tempered-glass back.
