AK4493 DAC

At the heart of the digital-to-analog conversion stage is an AKM AK4493EQ DAC, ensuring excellent audio performance. The AKM AK4493EQ DAC has a very low distortion of only 0.00017% (-115dB) and a wide dynamic range of 121dB, for rich, accurate and lively sound.

The chip also supports high sample rates up to 32bit 768kHz PCM and DSD512 for a high-definition listening experience.

Bluetooth

Practical, the Loxjie D30 allows you to transmit your audio files remotely, in Bluetooth, directly from your smartphone. The Bluetooth 5.0 standard combined with the aptX protocol allows for a stable and high quality transmission.

Filters

The AKM AK4493EQ DAC chip AK4493EQ offers six digital PCM filters to adapt the sound reproduction to your audio system or type of listening.

Preamplifier mode

The D30 has a stereo RCA preamplifier output. This "Pre-Mode" has 3 different parameters: The fixed mode locks the output level at 3Vrms, the variable mode allows it to take advantage of the volume control of the device and the DDSD mode, which allows DSD files not to be impacted by the volume level processing.

Components

The entire Loxjie D30 benefits from a careful design, based on components known for their audio quality. It includes the very good AKM AK4493EQ DAC, but also an AK4118A digital receiver of the same brand, allowing efficient processing of digital streams, while ensuring a very low jitter of only 49ps for the Coaxial input and 79ps for the Optical input. The USB input is associated with an XMOS U308 interface supporting audio streams up to 32bit 768kHz PCM and DSD512. The circuitry also includes a low-distortion, low-noise AOP LM4562 and low phase noise oscillators.

Robust and elegant

The D30's components are housed in an elegant and robust Aluminum case, offering excellent rigidity that also eliminates case vibration, while limiting the impact of electromagnetic interference on circuits.

Excellent DAC
I use it via a USB connection to a Sony TA-F3000ES amplifier that powers the Wharfedale Diamond 230 speakers. I am very happy with the purchase.

Excellent appareil à prix raisonnable
Ce petit appareil a un excellent rapport qualité/prix. Le design est sobre et efficace. La finition est très bonne même s'il faut être évidemment précautionneux, notamment avec le connecteur USB-B. La restitution sonore est de qualité.
Configurations testées :
- connecté à mon lecteur CD et enceintes sans ampli, belle restitution sonore quel que soit le filtre utilisé.
- connecté à mon PC en USB, bonne restitution avec de grosses différences selon la qualité de la source (fichiers audio, vidéo, jeux, internet et streaming ...) et le filtre utilisé (avec purifieur audio en entrée de DAC).
- connecté à mon PC via Bluetooth, excellente restitution sonore à 3m, scène large et aérée, bluffant ... et plutôt cool pour supprimer les câblages !
Conclusion : je recommande vivement ce matériel au regard de son rendu et de son prix.
PS : merci à Audiphonics pour l'envoi très rapide, l'emballage de qualité et la traçabilité du produit.

Excellent appareil
Une découverte que ce petit appareil. Le DAC est très performant sur le papier, et à l'écoute aussi (Entrée USB - Flac 44.1 et 96: tout est nickel). L'ampli casque est précis et pas du tout agressif, largement suffisant en puissance pour mon AKG 702.
La sortie ligne (un ampli PP à tubes derrière) est sans défaut. On entend tout, et le son est très naturel.
Alim intégrée, ergonomie au top....
Le BT fonctionne bien (je n'utilise pas trop, juste testé.....). Ce n'est pas la philo de ce type d'appareil, je pense, mais c'est un plus.
Les 2 volumes (ligne et casque) sont indépendant et mémorisés: parfait.
L'écran n'est pas bien grand, mais l'appareil lui même est très petit. De toutes façons, une fois les réglages faits, on l'oublie, sauf éventuellement le réglage du volume.
Il me reste à explorer les filtres (il y en a 6) pour bien comprendre à quoi ça sert, et si ça s'entend.... Mais tout le reste est très bien conçu et facile à mettre en oeuvre, aucune faute de goût.
Et à ce prix là.... Rapport Qualité/Prix imbattable. Même pour le DAC seul!
Merci au support technique Audiophonics (Mr Aubert) pour les conseils avisés.

Excellent DAC & Preamp
Great quality DAC with impressive stereo soundstage, simple but flexible menu-based configuration and uncomplicated remote control. Used as preamp, switching between USB (macbook) and TOSlink (TV), to active monitors or headphones (with independent volume control). Unbeatable quality and features at this price point.
