Topping G Series G5 Portable Headphone Amplifier and DAC, Black Overview
The Topping G Series G5 Portable Headphone Amplifier and DAC gives you a way to upgrade your audio on the go, with three-stage gain control to adjust output to match your headphones. With up to 21Vpp output on high gain for power-hungry models and low gain to keep sensitive in-ear monitors free from hiss and distortion, you can match whatever you're wearing. The onboard ESS9068AS DAC processes high-resolution audio with support for PCM up to 768kHz and DSD512. Paired with the NFCA amplifier—adapted from their highly regarded desktop models—it provides low-distortion output, offering the kind of precision typically found in more expensive setups.
For wired listening, the G5 offers both USB and AUX inputs, giving you the flexibility to connect to a wide range of devices, including phones, laptops, and dedicated audio players. The 3.5mm and 4.4mm headphone outputs also let you choose between standard and balanced connections. If you prefer to go wireless, the G5 supports Bluetooth with LDAC, allowing you to stream high-resolution audio with minimal compression. The onboard QCC5125 chipset ensures stable connections and broad codec support, including AAC, SBC, aptX, aptX HD, aptX Adaptive, and aptX LL. Whether you're plugged in or streaming, the Topping G5 give you pure, portable sound without compromise.
