Topping E30

USB DAC 32bit-768kHz / DSD512 XMOS

Topping's E30 is a USB DAC with very compact dimensions and surprising performances for its size. It uses a AK4493 DAC chip which is among the most famous compopents in High Fidelity Audio for this purpose. It also uses a Xmos interface providing a clear and transparent connection to any digital sources with a USB output.

This DAC has a volume control function which can be bypassed to use it either with a preamplifier or directly with active speakers or a power amplifier.

Topping has not forgotten to work on the product looks, since the E30 has an elegant and readable display accompanied by a beautiful touch control button.

Review by Audio Science Review

Distortion levels are incredibly low at -120 dB and lower. The addition of noise takes SINAD down to 112 dB which is most competent for a small little DAC like this:

 test by the measurement forum Audio Science Review


Digital to Analog audio conversion uses a AK4493EQ 32-bit Dac chip.  This modernized version of the famous AK4490EQ benefits from better distortion and signal-noise ration than its parent while keeping all the technologies that made it popular. It includes the famous Velvet Sound technology with increasingly accurate digital filters.

The USB input is controlled by a XMOS interface that enables to properly support very high sampling frequencies (up to 768kHz 16 and 32bit). This component also provides native DSD  compatibility up to DSD512 in addition to the DOP256 support.

When starting DSD through Foobar, a plop can occurr at the beginning of tthe first track.

These components are rigorously integrated and allow the E30 to achieve a clear signal with an extremely low distortion rate of 0.0003%, less than -130dB crosstalk, 121dB signal noise ratio and 119dB measured dynamic range. This kind of performance is usually found in more expensive and bulky equipment.

Impressive connectivity for its size

Unlike the majority of compact DACs that use a micro USB port, Topping gave its E30 an USB-B port. Thus giving it is a great advantage in terms of robustness and lifespan over its competitors.

The eneregy requirements are low enough to allow direct power supply through the USB port. There is also a DC jack which is ideal for connecting the E30 to any Hi-Fi grade power-supply (LPSU) without using any adapter.

A Coaxial SPDIF and an Optical SPDIF input enable the DAC E30 to work with external digital sources. Multiple devices (CD player, TV, media platform or game console) can be connected and enjoy its excellent audio decoding capability.

Its SPDIF interface use a CS8416 low-jitter chip, which supports digital audio streams up to 24-bit / 192kHz.

The touch button on the front panel can be used to change the active source. The source selection can also be done using the included infra-red remote control.

The output is a simple RCA stereo connector with variable volume.


Infrared remote control

The E30 comes with an sober infra-red remote to control all its functions remotely. This is a very rare feature in this price range.

5 etoiles mais j'ai bien failli le renvoyer ! attention à l'alimentation
Après de nombreuses lectures sur le net (audioscience review et consor), j’ai décidé d’acheter le Topping E30 – en remplacement d’un ARCAM Rdac defaillant.
Mes premiers essais ont été faits en « optique » avec une alimentation de chargeur de smartphone (2A). Le son m’est apparu montant, creux dans le bas medium, les basses sèches mais comme « décharnées ». En clair … pas bon du tout. J’ai tenté d’alimenter avec le PC fixe, PC portable – sans résultats probants.
J’ai joué avec les filtres et le Mode PRE ou le mode DAC, rien n’y faisait.
J’ai donc changé pour l’entrée USB (en tenant des échantillonnages sortis du PC allant de 44.1Khz – 16bits jusqu’au 32bits 392Khz …) toujours pareil. – le son était creux.
J’ai changé d’alimentation (alimentation linéaire 5V – 3A) – pas franchement haut de gamme. Idem.
J’ai mis une grosse batterie (10000mAh) pour recharger les smartphones … et là, j’ai enfin eu un SON équilibré (ouf) !
J’ai ressorti du placard une alimentation linéaire régulée (TL431+ MOSFET ) (transfo de 100+VA !)
Et là, j’ai retrouvé les résultats obtenus avec la batterie.

A FINAL : sur le net il est écrit partout que le DAC se satisfait de n’importe quelle alim, mais chez moi, avec mon système (preampli et ampli Primare + Open baffles 3 voies (2x30cmpar enceinte) ) et mes oreilles (et celles de toute la famille) , l’alim joue un rôle fondamental (bien plus que les filtres).

Une fois le problème d’alimentation réglé, le DAC est EXCEPTIONNEL pour son prix. La scène sonore est énorme (il y a de l’air entre les instruments), on localise parfaitement les instruments, les détails sont là, ils fourmillent. Les instruments sonnent parfaitement (timbres) , même les saxos/trompettes qui peuvent parfois être agressifs. Les voix sont retranscrites impeccablement. Les enregistrements de moindre qualité ne souffrent pas trop, on notera simplement une scène sonore plus petite, plus basse… Bref on pourra toujours les écouter !

Dac de très bon qualité.
Je l'ai acheté pour pouvoir partir plus tard sur des éléments séparés, ampli casque et dac. Je possède momentanément un Fiio K5 pro qui fais les deux. Lui aussi est de très bon qualité .
J'ai le associé au smsl q5 pro (acheté aussi de chez vous) Je constat que le son et encore mieux.
J'ai gagné donc un dac qui va me servir pour casque et pour l'ampli salon.
Merci Audiophonics pour votre réactivité et votre professionnalisme. Vous êtes au top.

Un régal pour les oreilles et le portefeuille
E-30 : superb clarity and finesse, even has decent op-amp for an entry level system (OPA1612).
audiophonics: fast shipping, newest factory charge (2102XXX), ordered in march.

tres bien overall.

I'm in heaven!
Until today I have been relying on the DAC of my AV amplifier, but I needed highres also for my new audiophile headphones, and AV amplifiers can't properly drive high impedence headphones. This little box connected to a good amp can truly sing! I've been using it with a few flac lossless CD rips and Tidal Hifi (24/96), all streaming from a dedicated Intel NUC connected through usb (Asio drivers) . I was surprised and delighted to get 24/192 when streaming Tidal Hifi from my Samsung S21 connected via USB: tidal on android can perform the MQA unfolding via software (presumably as the Topping e30 doesn't decode MQA).
I haven't tested the spdif or optic inputs and I am using it in pure DAC mode, mostly because I always want to visualise the sampling rate. The remote is useless for me after the initial setup.
As power supplier I'm using an old ipad charger which I am sure is cleaner than the power delivery from the NUC usb, but the power utilisation is so small that I could use a battery :)
I can't yet feel any difference among the DAC profiles.
A small click can be noticed whenever the DAC switches resolution, but I'm not overly bothered as I don't switch very often using my sources.
I can't imagine a better DAC at this price. If sound quality from usb is the priority I strongly recommend this

Very good
It works with a windows 10 pc without needing to install a usb driver, its's 24 or 32 bit, sounds a little dry and lively, easy to control either in dac mode or pre (preamp) mode for using it with active speakers and a tv or power amp and a pc (usb power).
