Soncoz QXA1: Balanced pre and headphone amplifier

Soncoz QXA1 is both a headphone amplifier and preamplifier, supported by a high-quality balanced architecture, using components selected for their performance and ability to provide clear and accurate sound reproduction. It includes a volume control based on the MUSES 72320 chip and a resistor ladder circuit that provides very low noise and distortion, four OPA1642 op-amps and four OPA1622 op-amps, ELNA capacitors and a power regulator based on TPS7A4700 and TPS7A3301 chips. The pleasant orange LED display clearly displays information about device parameters.

In addition, the QXA1 has a full range of connectors. It has both balanced XLR and single-ended RCA inputs. On the output side we find RCA for the pre-out, as well as a balanced XLR 4 pin and a single-ended 6.35mm Jack for the headphone output. Power comes from 5V DC via a simple USB-C port.
