Topping DX3 Pro+ Headphone Amplifier

Selling my Topping DX3 Pro+ desktop DAC/Amp as I've recently upgraded my setup to a FiiO K13 R2R.

Purchased new from Amazon in March 2025. It's in great cosmetic condition, working 100% perfectly, and has been used on my desk to drive a pair of HiFiMAN Arya Stealth Magnet headphones—which it handled with ease thanks to its high-power NFCA amplification.

Key Features & Specs:

DAC Chipset: ESS ES9038Q2M DAC + XMOS XU208 USB processor (supports up to PCM 32-bit/768kHz & native DSD512).

Amp Circuit: Built-in NFCA headphone module outputting up to 1800mW x 2 @ 32Ω / 250mW x 2 @ 300Ω—plenty of clean headroom for power-hungry planar magnetic or high-impedance headphones.

Bluetooth 5.0: High-resolution Qualcomm QCC5125 receiver supporting LDAC, aptX HD, aptX LL, AAC, and SBC.

Outputs & Modes: 3.5mm headphone jack, dual RCA line-out; operates as a standalone DAC, DAC + Headphone Amp, or Pre-amp.

Gain Settings: Two gain stages (+6dB low gain / +19dB high gain) for easy pairing with sensitive IEMs up to full-size over-ears.
