Topping E30 DAC Review
- Thread starter amirm
- Start date
Since the error code is private, the only way is to visit Topping.
If it cannot be restored even after unplugging the power plug and leaving it for about 2 hours, or if the factory default reset operation described in the user manual cannot be performed, it is a complete failure.

look the same tho...
still don't know about the specs....

If the E30 ll goes on sale, I think it's because the DAC chip has changed.
AKM has remodeled the AK4493 to the AK4493s.

I wonder if this Mk II model solves the SP/DIF input issues ?
Should (t)here be a knowledgeable & merciful soul to answer my simple question:
do I need to fix anything for my Topping E30 serial no. 2101... used exclusively for music streaming by phone via USB OTG (so no PC/laptop) ?
Thanks.

If it ain't broke, don't fix it, right?
The digital audio transceiver was changed from AK4118 to CS8416 in the wake of the AKM fire accident.
From this time on, S/PDIF connection failure began to be said, but I do not know if it will return to AK4118 again with this E30 ll.

Is this discussion about the coax output possible failure or else ?

Here are the specs
Note the kept costs down with no Bluetooth, MQA decoding and no balanced I/O. Otherwise, why buy the more expensive DACs?
'DIR" specs imply that it's solved. https://www.tpdz.net/productinfo/869064.html
My apologies if this topic has already been covered before.
I have an E30 connected to a Bluesound Node via USB. The E30 is in DAC mode. The Node recognizes E30 - I can select it as an output, and all plays fine.
However, I can control the volume in the BluOS app: change, mute, set min / max level. Is this expected?
My understanding was, that with an external DAC the Node will act as just a pass through and not process the signal in any way.
Before the Node I had a Raspberry-based Volumio set up and noticed that despite the E30 being in DAC mode, Volumio too was able to control volume. Setting the mixer to 'none' (vs. hardware and software options) never survived RPi reboot and the mixer reverted to 'hardware' every time.
Based on these similar experiences I conclude that E30 is the culprit.
Would appreciate any insights into the issue. Thanks!

That's true for SPDI/F but the XMOS firmware expose to USB a DAC with volume. So I suppose this volume is done by the XMOS.
As you have a raspy you could see and control it with the command :
alsamixer -c E30
Thank you very much. Unfortunately, I don't have the E30 connected to the RPi anymore, but I'll try to set it up again and check.
I have a Chromecast audio connected to the E30 via optical and I'm still able to control the volume from my phone (while E30 in DAC mode). I guess there's a digital attenuation applied from the chromecast side just as your bluesound applies digital attenuation in its usb out. Only in DSD mode no attenuation is permitted and you should always have your Foobar2000 (PC) or other app in full volume to work.

I have tried optical from the Node to E30 - this setup allows enabling the fixed output mode in the BluOS app. It's the USB specifically, which provides no option for a fixed output.
So, I guess it's just how E30 is designed - it would advertise its volume control to devices capable of understanding that. And DAC mode would just lock the volume for the Topping's remote.
P.S. I tested another USB DAC: the CA DacMagic XS. Same thing - Node can control the volume. But then again, the XS is a pre-amp as well.
UPD: found a thread in Bluesound support forums with multiple reports of the Node not enabling fixed output for various external DACs, including E30. Supposedly, it's caused by the Node's Linux-based OS (which is plausible as I've seen similar behaviour with the Volumio / E30 setup).
