The construction cone reminds me of Where's Waldo. Waldo would be a good avatar for ASR member @TOPPING-Service

They call constructions cones, “witches hats” in Australia, but they are not overly woke.

On the iPhone, you get the picture of the pier going out into the lake, hence my comment.
Yes I thought that was pretty funny. And the text box was especially commical.
Adding no value to the discussion- but I did vote and I’ve not had a problem so far. I am also including my photo proof of ownership. I have vested interest in the ongoing issues with the pa5. Owned since Nov 2022… so actually no leg to stand on if it does fail. In hindsight I was chasing the SINAD.. but it is a good sounding amp.

My PA5 just started having issues the other day. I bought it almost a year ago in March 2022 and last week I noticed these weird popping/artifacting sounds coming out of the left channel. I turned the unit off and later in the day turned it back on to test it out. The popping went away for the most part but there was a noticeable hiss/noise prevalent in the left channel that wasn't there before. Comparing it to the right channel, the right channel was practically completely silent. I've noticed a decrease in detail ever since I heard the popping sounds so I'm sure its the same issue everyone here has experienced. Its a shame, the unit sounded great while it worked, close to the sound quality of a Purifi amp I have. I have a few Topping products and its sad to see such a fumble on their end with this product. I wonder if anyone has had luck fixing the unit themselves.

I tried it out without any connections but the speakers and there's still issues in the left channel. It now makes this whirling ghostly noise, most likely a component going out/failing. Luckily I got a full refund through the store I bought it from. My Topping DACs so far have been solid as a rock (knock on wood).
Usually the power supply is a risk from needing to supply a large inrush current.
The amps just have an undisclosed fatal flaw that causes them to go bad; and it is when others using the same chips do not fail so dependably.
Thanks. I did read the first dozen or so pages of this thread and they were all about the power supply, start up spikes etc.
Would a higher current rated power supply, combined with a soft start, assist as it may be abe to handle more current and the start-up spikes, or is the fatal flaw not power supply related in this way?

The flaw is in the amp, not the PSU.
Okay. Thanks!
I do not recall Topping advertising what the flaw was, but maybe they did.
It seems like they have been pretty quite about the failures.
Agree. It does seem strange, that a company with a good reputation and good products should suddenly do this. It would be helpful if topping stated the fault then it coud be repaired by the end user. I mean it's ony an amplifier how difficult can it be

Amir's already stated that he won't be adding warnings to reviews as a result of anecdotes:
Topping E70 randomly went to MAX volume..
Strange, doesn't the e70 even have a programmable max volume set when you start it? So far at least my DO100 and C200 has done nothing like that.. neither have a DAC mode either, the volume cannot be disabled.

@threni
@amirm did say from that link
"I am providing the platform for you all to share your negative experiences here. There is nothing else I can do unless the problem is clear, and properly shown to be a potential issue. In which case, I have put warnings in reviews."
The question is... Does 48% of ASR's members exceed "anecdotal datapoints" ?

It's nothing like 48% of ASR members. Any number of internet comments are the very definition of anecdotal - or do the creation myths beloved of billions of fervent believers somehow become plausible once a statistical tipping point is reached?
