Totally agreed.It would be nice if Topping would/could say "The problem was found and now fixed. All PA5 shipped after September 1st are operational" (something like that)
Outrageous. Especially since when they decide it is advantageous to respond to your emails, it is a withering deluge of nonsense (asking for you to take videos of your malfunctioning amp, etc...) What in the name of reason does an iPhone video of a broken amp add??? So it’s not like they can’t respond, they do, but only after they got you at a disadvantage by running out the clock on you.I have had my PA5 since March, I was really initially impressed with the sound quality, but now it has started crackling and an audible whine in the left channel. I wrote to Shenzen Audio about the issue on the 14th August, they didn't answer until the 180 day period for their 180 Days up to the Quality of the Exchange or Refund had expired!
There is a reason and a specific term for this; tax-dodging. The don’t want to pay duties on the turnaround to and from China. Crooked. So it all ends up on you.Now they are saying return it for repair, with their unusual request to state the value at under $50.
Yeah, that is Shenzhenaudio’s address. They lost mine, or whatever. Told me lots of packages getting lost these days. I never saw it again, which is actually a good thing.The other thing is the address they asked me to send it back... is that the address of Shenzenaudio? Has anyone else sent a unit back for repair?
Same person I dealt with. I wanted to believe intentions were good, but the stench of scam was too strong. After 5 months, I just opened up on her and started screaming over email. She first refunded me 80% of the price, I accepted. I then sent a few more emails from the bowels of hell, and she refunded me the remaining 20%. So I got even I guess...Consignee: CaiYangyang

The broken A30 is sitting on my workbench, not sure if I have the patience or curiosity to look into it.
Disgusting terms of sale that they devised for supporting Topping product. I was a staunch Topping supporter but as I mentioned some weeks ago that all changed and I don't recommend it now.And never, ever, buy the brand again.
Dude, I wanted to like their kit so badly but I ended up with the same conclusion as you.Disgusting terms of sale that they devised fort supporting Topping product. I was a stanch Topping supporter but as I mentioned some weeks ago that all changed and I don't recommend it now.
Best advice yet, perhaps some alcohol involved!Make a youtube video blowing it up, or smashing it with a hammer- that will get them to sit up and take notice.
This was possibly the first post you made to me on ASR... Still true. I hate it when you‘re right!!!And never, ever, buy the brand again.
I'm going to go out on a limb and take a guess that the engineering of the devices is on the edge of performance and that means more heat, more stress and strain and more failures. Maybe it's time to back off the performance numbers a tad and add some features.@TOPPING-Service @JohnYang1997
The left channel has now completely stopped working. The left channel subwoofer only briefly comes on when the PA5 is turned on to make loud a popping sound that shakes the sub. Can someone from Topping confirm that the problem has been fixed and won't happen again? I haven't seen anything indicating this from Topping. Anyway, after this, I'm done with Topping and won't be purchasing any more of their devices. Good measurements are not worth the hassle.
Every Topping item I've ever owned seems to have had a flaw of some kind.
The L30 died and took headphones with it, the E30 reversed polarity, and now the PA5 left channel is dying. I wonder if there is a problem with my E50 as well.
Making audio equipment, Topping seems to be repeatedly demonstrating their incompetence.
.."add some features"...like reliability and durability if it can now be considered as features.I'm going to go out on a limb and take a guess that the engineering of the devices is on the edge of performance and that means more heat, more stress and strain and more failures. Maybe it's time to back off the performance numbers a tad and add some features.
I don't want to defend Topping, especially not, but in general the after-sales service has deteriorated, including with the big brands that have technical stations in the countries where they sell.Over a bunch of years I estimate that I've serviced about 55K units of electronic repair and many many of those where due to heat. Near everything I've seen was broken in that aspect. So I'm on board with that. It's not malice. It's just design or lack of qualifying the design and components.
Could you explain this more. It’s sounds relevant to my own situation and a question I’ve been trying to understand. I connect an SMSL Do100 DAC to my PA5 via XLRs for streaming from my PC in my home office. The PA5 runs warm even when there’s no music playing, unless I put it in standby. Neither of my two previous desktop amps (a Topping from 2016 and 20 watt Lepai class T) got warm like this when left on without music playing. It seems like a Design 101 flaw by Topping. With all the heat and electricity problems others have described with his amp, I want to do what I can to extend its life.These failures within normal???
Wtf
No these failures are high.
I knew it was over heating problem. Iam using a mates pa5 he had the problems but we attached a fan blowing into a side vent Problem went away.
And is still working fine.
It could also be that pa5 likes 2.6v
I bet folks are using full 4v. Dac on full volume. Dac needs dialling down 3.5 dB.
Which explains getting hot = failures
The volume setting of the SMSL do100 will make no difference to heat dissipation of the PA5. I have the same DAC and Amplifier. The PA5 has a volume control which essentially attenuates the signal from the SMSL so that the result is exactly the same for the PA5. The only thing you will achieve by turning down the SMSL is a lower signal to noise ratio due to the digital volume control.Could you explain this more.

The question — if I cut the volume out of the SMSL DAC, will that reduce the voltage into the PA5? And might that help? (I’ve been running it like this the past few days. It still gets warm but I have no idea if it’s less warm.) I’ve read here in the forums that the issues seems to be associated with 4v output from a DAC. Quite a design flaw given the PA5 only excepts XLR cables typically bringing higher voltage.
Appreciate any advice or tips for living with this thing now that I own it.
I will say that other than my anxiety over the warmth, and the possibility of fire, I like the performance. Sure is a pain though to always have to be worried about turning it off. That’s not something I have had to worry about with my other amps — class A, A/B, D or T — which either run cool at idle or have internal power off functions when there is no signal.
Dear XXX,
We apologize for the inconvenience.
We certainly remember that we told you that it would be sent to you via DHL/FEDEX.
However, due to the impact of COVID-19 during that time, the area where our company is located cannot send DHL/FEDEX, so it can only be sent through USPS. We apologize for this. We are also very helpless.
Regarding the situation of this package, the latest news we got from the logistics provider is that this package will arrive in the United States probably tomorrow or the day after.
The tracking number may change.
Anyway, we just want to let you know that we have daily inquiries with the courier and have been tracking this package for you.
Apologize again.
keep in touch,
Judy (Aoshida hifi)
It's a great progress just to receive such an email from the shop.An update on my situation: my amplifier is still in transit back to me. AOSHIDA told me they would send it FedEx, then sent it via postal mail. Here was their reasoning:
Sounds like a lame excuse, but I have no reason to doubt it. The end product is a longer wait. My satisfaction continues to decrease.
Sounds like you're dealing with Aoshida? Sounds exactly like the same process I have been going through. My unit is en route back to me, will let you know the outcome.Just spoke with amazon. They offered a return with a restocking fee. I declined. I got "escalated" to someone who told me that I should follow the instructions given by the seller (which included committing perjury). They didn't give a shit that the warranty promised on their website by a seller was fraudulent.
Not surprised by this, but figured it was worth trying for completeness.
