Then perhaps they should design in sufficient protection from catastrophic failure and test actual real world scenarios rather than sending in something half baked that they know will top the charts and sell a few thousand units of before the failures get reported ?...I very much appreciate the truth in the above but if everyone thinks like this the manufacturers are in trouble...
Corrected the post. Copy below. Thank you.bad link
My Qudelix 5K have this feature where i can't increase the volume if audio is not playing.
So if I sat on it the increase will take a few seconds to build up giving me time to pull out my IEMs.
Needless to say that have saved my hearing a few times.
my MiniDSP products never showed the issue OP is talking about either. so that's a solution for Stereo people.
Edit: They have now new DAC drivers on their WebsideSince last October, Topping is totally quiet, nothing heard from @JohnYang1997
anymore, no maintenance, on their web side.
They are still in business? Or sell the distributors only the rest.
Any betaEdit: They have now new DAC drivers on their Webside
so only missing @JohnYang1997
A firmware won't fix the possibility of the unit glitching out. This could happen with every DAC that uses a digital volume control.
Just use the DAC in fixed mode and adjust the volume with a preamp.
The point I was trying to make was this was not a one off incident. Two of us had the same situation occur so Topping needs to either come up with a fix or tell customers not to use it as a preamp. My guess is that every single E70I've had Logitech (Squeezebox, Transporter), Chord, 2 or 3 Benchmark, Motu, a crappy Emotiva XDA1, OktoResearch, etc - over the past 15+ years and this is the first time I hear about such a problem...

How exactly did it happened?I have a new Topping E70 and the same thing happened to me this week. Out of the blue the volume shot to max while on preamp mode. I was not touching the unit or the remote. This creates a risk to the speakers, amplifier and the ears. Hopefully it can be fixed by a firmware update. I may consider returning mine as it is only a week old.

After power cycling or during playback?
Yes,I have arleady seen that but our friend here is just saying that it suddenly went full volume without defining if it was after turning the DAC on or during listening to it.
It's a known risk, you just haven't been aware of it. I first saw it happen with a voltage controlled amplifier gain stage in a professional tape machine more than 30 years ago. Inevitably, I couldn't reproduce itI've had Logitech (Squeezebox, Transporter), Chord, 2 or 3 Benchmark, Motu, a crappy Emotiva XDA1, OktoResearch, etc - over the past 15+ years and this is the first time I hear about such a problem...
To answer your question, out of the blue with music playing, the volume went to full without me touching anything. I was listening to the music on floorstanding speakers and jumped out of my chair to try to turn it down. The unit was frozen in that the volume control did not work and had to be turned off. I turned it off - put it into DAC mode and stopped using it as a preamp.Yes,I have arleady seen that but our friend here is just saying that it suddenly went full volume without defining if it was after turning the DAC on or during listening to it.
That's scary,lets hope manufacturers will pay more attention against events like that.To answer your question, out of the blue with music playing, the volume went to full without me touching anything.

A frozen system happens mostly from a firmware problem. Please what is the actual firmware you are running?To answer your question, out of the blue with music playing, the volume went to full without me touching anything.
