TOPPING DX3 PRO+ DAC ES9038Q2M NFCA Headphone Amplifier Bluetooth 5.0 aptX HD LDAC XMOS XU208 32bit 768kHz DSD512 Silver

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:

Très satisfait
Produit livré rapidement et parfaitement emballé . Ce site est très sérieux et hautement recommandable . Le Topping DX3 pro + , offre pour moins de 200€ d’excellentes prestations . Sous un format compacte on trouve un préamplificateur un Dac et un très bon amplificateur casque , il drive actuellement mon Focal Elear sans problème. La construction respire le sérieux et la solidité , et son écran est utile et visible de loin , le gros plus dans cette gamme tarifaire est la …. Télécommande , vraiment appréciable ( toutes les fonctions de l’appareil s’y retrouvent ) . Je pense que l’ajout d’une bonne alimentation linéaire améliorerait d’avantage cet appareil . Même en rodage il a une excellente musicalité . Je recommande vivement ce produit qui pour cette somme , a un RQP exceptionnel.
