AIYIMA DAC-A7 HIFI Headphone Amplifier ES9038Q2M Audio USB Decoder Preamp Bluetooth 5.4 for 3.5/6.35mm Headphones Active Speaker
Audio/IEMs
“The Aiyima DAC-A7 pairs an ESS ES9038Q2M DAC and a TPA6120A2 headphone amp with socketed OPA1612 op-amps and a Qualcomm QCC3084 Bluetooth 5.4 module (LDAC/aptX HD). As a compact USB-C/optical/coax desktop DAC + headphone amp with switchable RCA pre-out, it delivers powerful drive and neutral presentation for entry-level audiophiles, though it lacks some high-end clarity/features and a bundled power adapter.”
