Topping E30 DAC Review

[Pinkerton65]

I guess it is indeed concerning, but as I said before, no reason to extrapolate to different products. But better ask if not sure, no problem with that. Just add a source of information next time. Will make is much easier and faster to answer

@voodooless
I think you weren't very kind. I asked for opinions from those who know more than me.

Topping does seem to have had some reliability issues with some headphone amplifiers. First the one in the DX3 Pro V1, and now older revisions of the L30(?)

I'd wager it's some unfortunately design choises in relation to the unpredictability of what headphones will be used with the products and how.

I wouldn't worry about the DACs.

 

[Pinkerton65]

Presumably a reference to the failure mode on the L30 that's causing a lot of noise over the last several pages of that review thread. 'Explosion' may be too strong a work, but there's at least one charred opamp, and a picture of a destroyed headphone voice coil among the multiple reports of failed amps and blown headphones. Topping are offering to replace L30s from batches before December's production. The situation is still evolving.

But DAC hasn't also an output for headphones? (1000 mW)
Thanks for the kind answers

The E30? Nope, it's just a DAC. USB and spdif/toslink in, RCA out.

Sorry, you do your first post on the forum starting with with some outrageous claim without any sources.. I wasn’t very sure if it was a troll or something else. Being a bit blunt usually resolves this question quickly. Luckily it was the latter

And if I had Dac Topping Dx7, I should feel worried?

Many thanks! @PSO

No problems @voodooless, I was in good faith, but it could have been misinterpreted

Sorry for the word "explosion", but I read some Facebook warnings that caused a lot of concern

Is uapp a really a must, specially on Android devices? How much of an upgrade to sq does an app like this do? Because technically every dac installed on Android device will be needing it every time as it is dependent on the Android sound system.

Is it a "must"? No. You can use the Android system driver if you'd like. It'll upscale everything to 48kHz, i believe. UAPP bypasses the Android driver and uses its own.

Not its own driver, but the lower level interface introduced a few Android versions ago to cover pro audio or low latency requirements. It's a similar situation to WDM vs. ASIO or PulseAudio vs. ALSA.

hi every1 , im experiencing a problem with my e30 ... as soon as the dac is connected to the pc for either power or usb.
there is a really high pitch sound .. like a ground loop but the sound is different , i would compare the sound as a coil wine sound from graphic card.!?!
its only happening in games , or hvy demanding apps . and as i navigate ingame , the pitch sound change tones.
when i am using spdif , its completly gone.
When i switch to spdif but the usb still connected , the sound is still there. I have to unplug the usb completly to get rid of the sound. Ive tried different usb and its all the same.
The dac dsnt even need to be power on to ear the sound ..

So basicly to get rid of the sound , i had to use a usb phone charger for power and spdif from pc...

That sounds exactly like a ground loop issue. The coil wine -like sound when the PC is working hard is a classic symptom.

how do we fix this ?? I had many amp and many dac to the same pc, and never experienced this

 

[Killingbeans]

You say phone charger + spdif works. Why not just use that? Do you need the spdif output for something else?

Or, you could get your hands on an USB isolator.

true. How the e30 performance using spdif ?

 

[Killingbeans]

The same as USB:

The only limitation is the sampling rate up to 192kHz.

Perfect ! If there is no advantage going back usb than spdif solved my problem. And i have no files over 96
