TOPPING DX3 PRO+ DAC ES9038Q2M NFCA Headphone Amplifier TPA6120A2 Bluetooth 5.0 aptX HD LDAC XMOS 32bit 768kHz DSD512 Black

USB XMOS XU208 USB Interface

In addition to this ES9038Q2M DAC chip, there is a second generation XMOS XU208 8-core USB interface, in charge of processing the data transmitted via the USB input. This one allows notably the support of high resolution audio streams, with PCM up to 32bit 768kHz and DSD up to DSD512. This chip also offers excellent compatibility with the majority of systems, whether the device is running Windows 10, Mac OS, Linux, iOS or Android.

QCC5125 & Bluetooth 5.0

The DX3Pro+'s Bluetooth 5.0 reception is provided by a QCC5125 chip designed by Qualcomm. This allows the DX3Pro+ to benefit from Hi-Res Wireless certification, thanks to the support of high-quality transmission codecs such as aptX, aptX LL, aptX HD and LDAC.

To achieve even better performance, this Bluetooth input is directly linked to the ES9038Q2M DAC for decoding the audio stream.

Preamplifier Function & Output Modes

The DX3Pro+ offers a preamplifier function and no less than four output modes to suit different uses:

Excellent rapport qualité prix
Fabrication propre , pratique à utiliser, aucun problème à l'installation. Il drive très bien mon hifiman sundara.
Au niveau sonore, c'est exactement ce que je recherche et rien à lui reprocher.
Le seul défaut que je vois est le bruit que fait l'alimentation au niveau de la prise. C'est léger mais suffisant quand je n'écoute pas le casque pour que je regarde à la remplacer.
