TOPPING E30 II DAC 2x AK4493S XMOS XU208 32bit 768kHz DSD512 Black

Dual AKM AK4493S DAC

The main improvement of the E30 II is its digital/analog conversion stage. It now uses two AKM AK4493S DAC chips connected in parallel, each dedicated to a channel, thus offering much better performance. These chips are themselves improvements of the AK4493 chip. They also benefit from the proprietary Velvet Sound technology and ensure a sound reproduction that is both precise and rich in detail.

XMOS XU208 USB Interface

The USB-B input of the E30 II allows a simple and powerful use of the DAC. It is associated with an XMOS XU208 interface and a particularly stable and reliable Thesycon custom driver. Moreover, this input ensures an extremely low jitter level. The combination of this interface with the AK4493S DACs also allows the E30 II to support high resolution audio streams, up to PCM 32bit 768kHz and DSD512.

Discrete LNRD circuit

In order to solve the noise problem that can be caused by the 5V power supply, the E30 II includes a discrete LNRD (Low Noise Reference Driver) circuit. It filters the noise from the 5V power supply to provide an ultra-low noise and stable electrical signal to the audio circuits. Thus, the background noise of the E30 II is less than 1.5µV.

Entrée coaxiale pas compatible avec toutes les sources
J'ai acheté 2 exemplaires pour remplacer mes FDA en sortie d'un MINIDSP nanodigi (coaxiale) malheureusement cela ne fonctionne pas correctement, nombreux crépitement (leur fréquence dépend du contenu musical) ; Les 2 exemplaires ont le même soucis; En dehors de ce problème la qualité du son est bien meilleure que mes FDA et bien meilleure que mon DAC1 Benchmark donc je suppose qu'en USB c'est un très bon DAC; Bravo à Audiophonics pour son service impeccable.
