The xDuoo TA-10 Tube DAC Amp comes with the flagship AKM AK4490 DAC and the classic 12AU7 tube. It is fully balanced from input to output and comes with the XMOS 8-core chip. For inputs, it includes two aux inputs and USB, and for outputs, it has SPDIF and RCA out. The single-ended output from the TA-10 works well to deliver the same high power and accuracy even if you don t have a balanced headphone. Made out of CNC aluminum alloy, the TA-10 makes a great addition to your desk.
