Bluetooth 5.0 LDAC

If the DX3 Pro already had Bluetooth connectivity, it is enhanced in this V2. The CSR8675 chip offers Bluetooth in version 5.0 and supports, in addition to aptX and aptX-HD for high audio quality, LDAC, which allows 24-bit file playback. In addition, the internal DAC of the CSR8675 chip is not used. This is directly linked to the two AK4493 DACs, which are much more efficient, for digital/analog decoding.

USB XMOS XU208

The XMOS XU208 chip used for the USB interface of the DX3 Pro V2 supports files with high sampling rates. Thus, using this USB input it is possible to enjoy PCM files up to 32bit 768kHz and up to DSD512 Native. Topping also took the time to offer a custom version of the Thesycon USB driver to ensure better compatibility with computers running Windows.

Dual AK4493 DAC

The heart of the DX3 Pro V2 is most certainly its digital-to-analog conversion stage. It uses two AKM AK4493EQ chips, one per channel, which greatly contributes to the audio performance of the device and also allows it to support high sampling rates.

S/PDIF AK4118 Receiver

On the S/PDIF Coaxial and Toslink Optical inputs side, the DX3 Pro V2 uses an excellent AKM AK4118 receiver chip to get the most out of these connectors, supporting PCM sampling rates up to 24bit 192kHz.

DAC + Preamplifier Application

The DX3 Pro V2 offers the possibility to be used as a DAC combo and preamplifier to be associated with an amplifier or active speakers. To do this, simply set the output mode to preamplifier. The signal is decoded by the DAC section of the DX3 Pro V2 and the volume level can be adjusted directly via the front panel button or the supplied remote control.

TPA6120A2 Headphone Amplifier

The DX3 Pro V2 also features a very good headphone amplification stage based on a TPA6120A2 chip. It allows to develop a power of 2x 700mW under 32Ω or 2x 125mW @ 300Ω allowing the DX3 Pro V2 to accompany a very large majority of headsets. In addition, the gain is selectable, in 0dB or 9dB.

Très polyvalent
Voulant controller tout mon système (casque Stax, enceintes de monitoring et casque dynamique) j'ai revendu mon Topping D50s, un ampli casque dédié et un préampli passif pour ce DX3Pro.
C'est hyper pratique. On passe facilement d'une line out DAC 2v pour le Stax à une line out preamp + ampli casque avec réglage du volume.
Très belle fabrication, la V2 n'a plus les problèmes de fiabilité de la v1 et le BT LDAC est un plus avec mon smartphone.
Côté son, c'est clairement excellent, très neutre, peut être un peu moins de présence dans l'extrême grave et de séparation des instruments qu'avec le D50s.
Le gain en polyvalence est sans appel, c'est sans aucun doute le meilleur DAC que j'ai pu avoir jusqu'à maintenant.
Merci à Audiophonics, expédition de la commande très rapidement malgré le confinement.

Flexible, high-performance with minor usability annoyances
I do not have the equipment to measure the performance so I'm gonna refer to AudioScienceReview for that:
https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-topping-dx3pro-dac-and-headphone-amp.4967/
Summarizing the performance: it has great performance, as good as many units at 2-3x the price.
Things I noticed about the sound:
1. Noise is waaay lower. Quiet sounds are much easier to hear.
2. A slight shift in frequency response which I assume is down to by previous (integrated) hardware having high resistance (while Dx3 Pro has 1Ohm, which is excellent).
3. Noise from the PC is mostly gone. Previously I could hear faint noise when moving my mouse. That is no longer the case. I can still hear noise when pushing my PC hard, playing games, but I'm not sure if that's due to my motherboard having poor isolation. And this noise can only be heard in headphones, not through my speakers (Line Out in DAC-only mode).

Finally, my main gripes:
1. The volume knob is nice and clicky but can sometimes skip back the other direction at a slight touch; it's not as precise as I would have liked.
2. Even when setting Line Out as DAC-only in the settings it will use the Amp when you have Headphones AND Line Out active at the same time.

Overall a great piece of hardware with minor issues. Highly recommended.

Belle musicalité
J'ai trouvé la musicalité, neutre, précise et détaillée, exactement ce que je j'aime.
Il y a des "filtres" (6) configurables. Je n'ai entendu aucune differences tant au casque qu'en line out ... !? Leur utilité est un mystère pour moi, je n'utilise pas ce genre de fonction en général, ce n'est donc pas gênant.
L’accès au menu "setting" est plus qu'original !!
La portée (récepteur) de la télécommande est très faible, à peine deux / trois mètres ... ça c'est franchement gênant.
Le support LDAC pour du bluetooth occasionnel est un vrai plus.
En conclusion, je suis très satisfait par l'audio et je reste sincèrement sur ma faim concernant l'experience utilisateur.
