Topping DX5 II

Hopefully this doesn't delete the target curve/source FR for me again

It deleted my target curves, and source FRs again . None of the PEQ profiles were affected (just like the last time), though, so that's good. I will probably e-mail Topping about that.

You are on a Mac, right?

Yeah. I did e-mail Topping about this. I have requested v1.14 so that I may be able to capture a video to properly document the issue.

I clearly misread. I realize now that you're recommending they change the option in TT to shut it down when closing the window. Apologies. That's what happens when I haven't had enough coffee to fully wake myself up

We were having a short vacation a Holiday, so sorry for the late response. The apology wasn't needed. I really thought.... Yes, I forgot to show the location where to find the setting, good that you pointed to it. I personally think that no one is waiting for just the message that I solved a problem without showing exactly what I did. It's just that I dislike the default setting. I hate to have undocumented processes running. And certainly when the only functionality for me is signaling there is an update waiting.

OK, so, because my purchase was through a third-party seller through Amazon (Shenzenaudio DE Store, which is operated by leiyinaudio.com), there was no return option or anything on my order history on Amazon. The 30 day return window had long expired and the help pages and the chatbot directed me back to the A-to-z Guarantee page where you're told that:

When you buy from a third-party seller on Amazon Marketplace:

• Amazon only facilitates the transaction but isn't the actual buyer or seller.
• The sales contract is exclusively between you (the buyer) and the third-party seller.
• Amazon isn't a party to this contract.

So, last Friday, I contacted the international seller Shenzenaudio via e-mail and told them about my defective DX5 II. They took my description of the issue and said they would get feedback from a technician and get back to me. Today (Monday), after not getting feedback (yes yes it was a weekend, but still), I tried the Amazon chatbot again, but this time I pressed the right buttons and got to speak to an actual assistant.

The whole interaction then took literally 10 minutes max. I told him I purchased DX5 II in December and that now the unit was defective and that I wanted to know how to proceed, expecting him to tell me that due to third-party seller I should contact the seller directly etc. But he asked for a minute to check instead. He then came back and asked for another minute as he was checking with "another team". He then came back with a link and asked me to upload a picture of the unit, so I did. And after another minute he came back and said this:

After checking the item and the system, and since the item is defective, you can keep the item and we will arrange the full refund for you and you don't have to return the item, Is that okay?

I was shocked. They will refund me the full price, and I can keep the brick, which means I have spare parts now.

When I asked him why they wanted me to keep it, he said:

since the return fees will be high. I've requested a refund without return as an exception and they approved that.

I don't know if the "other team" was Shenzenaudio he was speaking to, but man am I happy that I went through Amazon. What an amazing support experience.

This is why I generally order these kinds of things through Amazon. Returning/refunds are so much easier.

My DX5 Mk2 died after about 2 weeks of light use, smoke free climate controlled. Returning to Amazon. I really liked it while it was alive. Won't even power on now.

You shouldn't repeatedly plug headphones into the 4.4mm port. The 4.4mm balanced output breaks easily and causes the device to short-circuit. It’s a problem that affects all of them (presumably).

I should use it as I need (and as is normal), which involves plugging headphones into various ports at will

Now that I have a brick, I thought I might as well take some pictures of it.

However, this is as far as I got. There is this ribbon cable connecting the board to the display, preventing me from pulling the board out.

Does anyone that has already disassembled these once have an idea how to approach this? Maybe from the front instead, but I have no idea how to get the front section off.

I always recommend to buy on Amazon and that Amazon is involved in the process if not as seller than at least for shipment.

Topping DX5II teardown

Hi. Could you please tell me how to disassemble the DX5 II? I took mine to a repair shop, but they didn't know how to disassemble it, so they refused to repair it. I’m interested in this as well, because once the warranty expires, I might try replacing the ATAZ power supply with a Mean Well or...

While I wait for my 15cm long 2mm Allen key to arrive, so that I can open my brick and stick my multimeter in it (not that I know how to use it, but it'll be fun), I was wondering if proper power regulation might be the main issue of the DX5 II, and if a DX1 II might be a better alternative for someone that just wants a DAC with PEQ, knowing that the DX1 II runs on less power, therefore cooler, and also isn't influenced by AC fluctuations as it takes its power from USB.

You can compare the reviews, and decide whether the DX1 II is a better fit.

I should use it as I need (and as is normal), which involves plugging headphones into various ports at will

When content is playing, there's a risk of things happening if you pull out/plug in headphones -- this is not really specific to the DX5 II. FWiW, I have connected/disconnected headphones from all of the jacks on the front of the unit countless times, and haven't had any problems. Never while content is playing, though.

Some of the accounts of the 4.4mm issue could be due to how finicky the 4.4mm jack is (the first time I used it, there was no sound from one channel, and the other one was crackle-y, but it was because it wasn't fully seated -- it was literally less than 1mm out of being fully seated), some accounts could be due to carelessness, and some accounts are definitely legitimate defects. Your unit not powering on is unrelated to this, though. That sounds like the power supply just died, which (again) isn't an issue that is specific to the DX5 II.

I did and it looks good on paper.

I'm just hesitant to get another DX5 II now until I manage to open this one up and check what actually went wrong with it. After 7 months of continuous use, always with the same headphone (and keeping it plugged in), and not even using the 4.4mm jack, the only variable I can imagine is an AC power related issue.

Maybe there was a surge and the unit has bad surge protection. If that's the case, then I'd know how to mitigate with the new one. But if it turns out to be a random component that just died (due to it running warm), then it'll be a gamble with the new one also.

What is the HW revision of your DX5 II? Mine is 0.15, but I know there's a 0.16 revision because (I believe) they changed the 4.4mm jack component.

FWiW, the DX1 II looks excellent on paper, and you probably won't notice a difference (the only tricky thing looks like the RCA output is weird).

It should be indicated on the sticker on the bottom of the unit.
