Guys this is driving me crazy, jack falling out every 5 minutes!! Anyone else have a better solution for a loose jack on the DPX1A? I know it's an old problem and am aware of the Hong Kong repair solution but that would be too lofty for this old DAP. Any makeshift solutions, perhaps something involving an expanding keychain tied around it, string of some sort... or what about a 2.5mm balanced to unbalanced 3.5mm adapter? Because at least my balanced connector still works great LOL.

If anyone has knows of a 4-pin 2.5mm. adapter for regular 3-pin 3.5mm headphone please post the link.

Also does anyone here have any impressions on the sound of the iBasso DX 220 vs. DPX1A? To me that's the logical upgrade path, but budget will take some time.

The only safe way to connect a Single-Ended load to a Balanced output, without shorting the L- and R- outputs together (which would damage the amplifiers), is to put series resistors between L- and R-, and the common GND point for the Single-Ended earphones.
To determine the minimum resistor values, take the maximum (+) and (-) voltage levels, and the maximum power output capability of the Balanced channels, and do a bit of math -
Resistance = Voltage [Squared] / Power

The 2 resistors would each be 1/2 of the Total resistance.

EDIT: The Voltage you use in the formula, is the difference between the most positive and most negative voltages.

It's hard to compare because one is a DAP and the other is a DAC/AMP. The latter "doesn't" have a DSP which affects the SQ.
Here are things I can remember when I connected the Mojo to the DP-X1 by USB and by transferring PCM. The Mojo gives more neural, less thin and clinical sound. Still it has a little of bass. Other said, the sound signature isn't much different between those two. The Mojo, of course, has a stronger amp. But for easy-to-drive IEMs, I didn't notice any benefits of representing details and soundstage. I felt it was waste to buy a Mojo to pair with the DP-X1 if I had no relatively power-hunger headphones or IEMs.
Sadly, I didn't try feeding DSD (DSF files or real-tine conversion) to the Mojo. Because DSD signals pass a different path in a DAC chip and reproduce a quite different sound from PCM processing.

merry christmas and HNY.
Enjoy.
I'v flashed twrp-3.0.2-0-Rai_Zin_32 .zip,then install CUSTOM DP-X1_0.1.37.8_VTX_Lite firmware for DP-X1,twrp report an error “failed to mount system”.
Now I can't boot dp-x1 to system. Bootloader and recovery are no problem.How to fix this?
Thank you very much.

Hi folks,

I have encountered some issues with my DP-X1A, maybe because it is upset about me purchasing a Fiio M11 and has given up. Yeah, probably not, but it is a bit screwy and I hope someone here can help.

As I said, I purchased the Fiio M11 and have decided that I will not hang onto the DP-X1A. So in preparation for selling it, I did a factory reset. And now, it won't start up properly. Like a previous forum member experienced, the device gets stuck trying to connect to the internet in the setup process but never seems to download anything, even though the internet connection is fine.

Here is a summary of some of the things I've done or encountered:

- After turning on, I choose my language and hit "next" followed by the selection of a Wifi network. It then checks for a connection and says this can take a while. If I let the screen time out and fade to black and turn it on again, that seems to bring a halt to the process and it says it can't connect. But if I keep the screen active, it keeps working at the "Checking connection..." stage although it doesn't ever update and I can't hit the "Skip" option at the bottom of the screen as it's greyed out.
- Occasionally, the settings menu can be accessed from the top of the screen. It's so random though. Most times, if I swipe down from the top of the screen, I get nothing. Then it activates and gives me the settings options on occasion. I can then go through all sections but I cannot tap on build number to turn on developer options (which I figured I may need to turn on to remedy this problem, based on some of the research I've been doing for this problem).
- I can tap multiple times on the Android version section and the Android Lollipop animation appears. If I tap on it multiple times, an Android "game" appears. I wonder if anyone knows this is here. I didn't buy this to play games though so I don't care.
- I've restarted multiple times and tried to restart the process but it invariably fails again.
- If I go into the recovery menu and attempt to load a firmware update from the SD card (which I thought might help), it cannot seem to identify an SD card or says it failed to mount. The SD card appears under the storage section in settings though (when I have been able to access that menu, intermittently) and seems to be mounted.
- I've attempted to sideload the update via ADB on the PC and it works fine - but once it gets to about 48%, it fails and the process stops again.
- This unit was purchased from the now-defunct DWI store based in Hong Kong two years ago so I have been rejected by the local Onkyo repairer options, as well as Onkyo USA who were no help at all. Physically, the device is fine. It's not broken. It's not a hardware problem. This device has been trouble-free for the entire time I've had it but it has only crapped itself following the reset.

Do I need to "flash a stock rom" to fix this, as I suspect? Would that remedy this? More importantly, does anybody here have a stock rom that they could share?

I'm comfortable tinkering with things if I have to and have been able to get partial success with the ADB option, as I said, but there seems to be a problem that consistently causes failure. For example, if I attempt to view devices using ADB, nothing shows. But if I run the command to sideload the firmware package, it reads the file, connects to the device and gets underway with it - only to fail again at around 50% completion.

If anyone can assist, that would be massively appreciated. I know there's life in this unit yet and I want to get it back to life so someone else can buy it and give it a good home.

Thanks in advance.

Anyone compared the SQ of the onkyo vs chord Mojo?
Hi

I have both but I must admit my Onkyo is very seldom used as a result.

The Onkyo has great versatility as an all in one unit but with Native DSD for example will not play without converting via PCM unless connected to a USB DAC along with a few other caveats.
I prefer the holographic sound stage from the Mojo and I even for a while used the Mojo as a USB DAP for the DP-X1.

These days I have the Mojo/Poly and have the Onkyo for times when I need to travel light or for MQA playback or when the battery is flat on my Mojo.

I have no regrets on owning both but for me the win goes to the Mojo sound quality wise

Well, something odd happened today on my rooted DP-X1.
While at lunch, I checked and saw that there were 6 updates from the Play Store (UAPP, Spotify, and some others) available - so instead of immediately listening to Spotify, I clicked on Update.
The update started, and then the screen timed out, and went off.
I logged back in, and saw that UAPP had finished downloading and was installing.
Then, the next app (not sure which one, but it wasn't Spotify - that was further down the list) started downloading / installing.
Less than a minute later, I noticed my DP-X1 was rebooting, and ended up in a boot-loop (shows the initial Android screen, and then the boot animation - over & over).
I long-pressed power to shut it down, and then booted into TWRP.
In TWRP, I cleared the Dalvik / Art Cache, and Cache.
Still boot-looping.
.
I'm busy this week, scanning slides, negatives, and photos for a family reunion - so I won't be able to do any troubleshooting until next week.
.
Do you have any suggestions for logs to check, that might indicate what is causing the boot problem?
Or, can you suggest System files than might need to be edited / replaced while I'm in TWRP, that could allow it to boot normally?
.
Thanks!

I am using DP-X1A to run a Focal Utopia (80ohm impedance). Some people say it isn’t powerful enough, but I get great sound, even at low2 gain. I do listen at low volumes. Mostly classical and jazz. I use UAPP (I find it much better than the Tidal app).

Any suggestions how to maximize the sound for the Utopia? Would an external headphone amp improve things? Should I use Low2, or higher gain? What about ‘lock range adjust’ and ‘Digital filter setting’. Frankly, I don’t hear much difference other than using balanced output.

Hello, in my opinion the most noticeable difference gives the change to the BAL out (regular BAL for loudness and dynamics improvements, ACG for the best clarity and sq overall). Next step is to set the lock range to the one step away from the narrowest. Of course for more juice nad power- High gain. And in the end- if you like even more forward mids then Filter Short. Sharp gives you the biggest soundstage and peaks in hights. Slow evens everything, making everything flatter, short pushes mids forward.
