I guess you didn't read the part in the thread where I corresponded with Shenzhen Audio for 6 months going in circles with no resolution.
Or the part where I reached out to Topping, over and over but was ignored.
And you didn't bother to look where I reached out to John Yang directly several times, only to be ignored.
And you missed part where John Yang and a Topping customer service representative actually rejoined this thread, with total emptiness, only to disappear again, like ghosts, leaving us even more bewildered.
And, it seems that you either missed the part where I have multiple Topping products that failed, or you just love working with customer service on broken devices with bad solder joints, or whatever. Did you have to work with Topping for many months with no resolution on your "technical problems"? Were your "technical problems" really broken product, like did they not play in one channel, or make strange noises, or did you have a several volt DC bias on an output?
What are you talking about??? This thread is called "for Topping PA5 owners only" and is specifically about the reliability of this product, are you reading any of this??? Did you buy a PA5? If not, you are kind of trolling us with your stories. People actually bought this stuff, and weren't able to use it for months, or in some cases forever. And they can't seem to get customer service for a replacement or their money back. People feel ripped off, your ability to understand this basic fact is bewildering.
