Won't that just mean the Oppo still does a conversion before outputting so you still will be limited by the Oppo's abilities? I'm not sure and maybe I'm missing something.

yes your DAP then just becomes a transport

  Correct, the US version I received was in the same packaging that serves every market and suffers the same QC issues. The advantage is the US warranty support and availability of 3rd party warranty extension plans, etc.
 
I couldn't bite on a grey market model for reasons discussed earlier in the thread, and sure enough-- my 2.5 jack has a hell of a gap. With full warranty support, I'm nowhere near as concerned about a malfunction. I'm not afraid of sugru, and I realize a warranty claim is feasible through PJ with an unreasonable (to me) turnaround time, but I'd prefer the route with less stress.
 
Still less expensive to import if you'd like to roll the dice, however 

How did you get the US version? it is not officially released in US market right? The only version I found on Amazon.com is Japanese Imports

Onkyo USA has been selling them domestically for about a week. Choose 'other sellers' via the main Amazon listing @ http://amzn.com/B01AWLQ1AY to access the $799 listing by Onkyo USA themselves (blue logo). Don't concern yourself with other retailers for now.
 
Cheers~

There is no US version, they are just going to sell the same unit everywhere. Maybe eventually they will change the retail packaging, but the units are the same. Why would they produce more than one version when they don't need to?

sq3rjick-Well done bro. Thank you for sharing, it's much appreciated. I'm going to do that on my X7, now that you did the hard part. Probably will take me a few weeks because I'm lazy.

  Just an update.  I spent the last few hours trying to replace KingRoot with SuperSU.
 
Success, and it survives reboot!
 
It's a little bit complicated, but not too terribly so if you know anything about the command line.  You can do this entirely from the device itself, which is nice.
 
1) Download KingRoot: http://www.kingroot.net/tutorials
 
2) Make sure you have enabled "Unknown Sources".  This can be found by going to Settings --> Security --> Scroll down and under "Device Administration" make sure the "Unknown Sources" is checked.
 
3) Open the downloaded KingRoot APK file.  You'll get a warning about this not being safe, with a little arrow.  Click on the arrow and click on "install anyway".  Once it is installed, click on "open".
 
4) Once the app is open, scroll down three screens and click on the "Try It" button.
 
5) Click on the big circle button to attempt root.  It will identify your device as a "DP-X1", and after a little bit it will say that there's no strategy.  That's okay.
 
6) Click on the new "run anyway" button.  This should take a few minutes.  Your device may reboot, but mine didn't.  After a few minutes, you'll be told that you were successful.
 
7) If you are happy with KingRoot, you can stop the process now.  You have root access.  I don't quite trust KingRoot myself so I wanted to replace it with a better (more well-known) alternative: SuperSU.  Warning: the following is intermediate level, and you very much could break your device.  Don't proceed unless you are comfortable on the linux command line and know what you are doing.  I take no responsibility if you brick your device, which is very possible to do.  However, if you do have some experience it's fairly easy and straightforward.
 
8) Before we get started, you'll want to install "BusyBox" and "Terminal Emulator" from the Play Store.  Do the first results for those exact searches and make sure they get installed.
 
9)  When prompted if you want to give them root access, select "grant" or "allow". Make sure you install everything with busybox.
 
10) Now comes the fun part.  Download the "replace kinguser with supersu v2.4" zip file from here: http://www.mediafire.com/download/mxzbt42xypvn2ts/Replace_Kinguser_with_SuperSU-v2.4.zip You'll want to extract it on your computer and move the "mrw" folder into the "/sdcard" folder in the Onkyo Android.  If you are using "Android File Transfer", the directory that you get plopped in by default is the "/sdcard" folder.  You can also use a tool like 'ES File Explorer" to open the zip file on your device and extract it to the /sdcard folder -- that's what I did.  But if you don't feel comfortable doing that, you can just extract on your computer and move over.
 
11) This part is a little bit tricky and requires a bit of juggling.  We are going to setup so we can remove kingroot and replace it with supersu.  Open the "Terminal Emulator" and type "su", without quotes, followed by the enter key.  You'll get a popup from KingUser asking you if you'd like to allow root access.  Grant/allow, and you will see the terminal prompt turn from a "$" to a "#".  This means your terminal now has root access.  This is very important: make sure you don't close this window at all for the remainder of the process, or you'll have to start over again from the beginning.
 
12) Now that you have the root terminal window, open the "kingroot" app.  Click on the three dots on the top right of the screen and go into the settings menu.  From there, you should see an option for removing kingroot and unrooting the device.  I don't remember exactly what it was called, but it's fairly obvious.  Click on that option and remove the KingRoot install.  You can keep a backup if you want to -- I didn't, but it should theoretically give you a better starting point if you need it later.  You may get a warning about it rebooting your device, but it shouldn't.  Make sure you don't reboot the device at all for the remainder of the steps.  If you reboot now before we install SuperSU, you'll lose root access.  This is why I had you open the root terminal window before -- we'll be making use of it.
 
13) After KingRoot is uninstalled, go back to the terminal emulator window that is currently running with root access from the previous steps.  You will want to enter:

 cd /sdcard/mrw

 and then hit the enter button.  This will take you to the exploit script.
 
14) We want to make sure we make the root filesystem writable (it normally isn't).  Enter the following command, without quotes, and then hit enter:

 busybox mount [color=rgb(102, 102, 0)]-[/color]o remount[color=rgb(102, 102, 0)],[/color]rw [color=rgb(102, 102, 0)]/[/color]system

This makes the /system directory writable, which is necessary for installing SuperSU.
 
15) We now want to actually run the script and install SuperSU.  Enter the following command:

 sh /sdcard/mrw/root.sh

Hit enter, and the fun will happen.  You'll see it attempting to clean up everything, and then install SuperSU.  Once it is finished, SuperSU will open.
 
16) When SuperSU opens, it will prompt you to update the binary.  Click "continue" or "update" to continue on.  When it prompts you for which way to run the update, choose "normal", which will install the binary to your /system folder that you unlocked earlier.
 
17) After a few minutes, you should be told that you are successful, and that you can reboot.  Reboot the DP-X1, and you should have full root access with SuperSU.
 
If for some reason you are getting an error when updating the SuperSU binary, you probably missed the step of uninstalling KingRoot before attempting to install supersu.  This was my biggest issue and took me the longest time to figure out.  You need to launch supersu from your root terminal window -- you can't just launch it from the app drawer after removing kingroot.  And if KingRoot is still installed, it actively blocks writing to the /system directory, so that's why you need to remove it before you install SuperSu.  Hence, you need to install the terminal emulator, grant it root permissions while KingRoot is installed (which will maintain its root permissions), uninstall kingroot, use the root terminal window to launch and install supersu, and then reboot to finalize everything.
 
Hope this writeup helps somebody else out.
 
I also didn't check out if we could simply do "adb root" from a computer to see if we can get root without all of the trouble.  Somebody else may want to check that for me before going through all of the steps that I did. 

after we root our dpx1. do we still get software updates in the future?
thx
 
================
and I want to ask, how to use the x-dap software? I already connecting my dpx1 to my laptop, still the x-dap link software didn't read the onkyo memory and my 2 others memory

For the root issue, please be reminded that we see two units in our chat group unable to update after root. They eventually need to send back to Japan.

There is no advantage heard for rooting the unit.

 

[warrior1975]

Problem updating if you root for sure.

Advantages of root, Viper4Android.

You can remove root and get updates. Then reroot.

 

[goldendarko]

What's the point of rooting this device? Doesn't it void the warranty ?

 

[masterpfa]

Does the DP-X1 have the same 2.5 Balanced output as an AK240
Because I already have the balanced headphone cables for the AK unit

Also has anyone successfully output to an external dac with an otg cable
I have an oppo105 linked to my whole speaker system with very good analogue output
and the oppo cannot play DSD 256 or MQA files
It's got a usb B input on it

Thanks

 
Yes and Yes

Same 2.5mm jack as AK240

The DP-X1 outputs via OTG to a DAC, no other output other than headphones.

 

[YugiRider2]

Just ordered one for about $580 shipped.
So this DAP can line out? Do I just need a 3.5mm to 2RCA cable and plug the 3.5mm end to the headphone output?

Where did you find one for $580? And why is a brand new item with an MSRP of $899 selling for over $300 less than MSRP already? Pricing structure seems very inconsistent right out of the gate.

Should be able to unroot if necessary and then re-update.  I'm not bypassing any efuse or flashing a new rom / bootloader.  Just using a software exploit to get root, and installing KingRoot --> SuperSU.  It's entirely in software and not in firmware at all.
 
I'm willing to be a guinea pig, and I know my way around Android devices, so I'm not too concerned.  I definitely don't foresee needing to send it back due to software!  I'm a software developer and I work on Android apps on the side, so it's not very daunting for me -- I think I'll be able to fix any problems as they arrise.
 
Like I said in the warning, this isn't for everybody.  But for those that do want root, it is definitely possible to get it.  For me, the ability to block ads at the system level is something that I do on all of my Android devices, and it was starting to annoy me a bit.  But I also like that I can install Titanium Backup and keep running backups of the apps and settings as different versions come out.
 
It is all about trade-offs, really.  If you want root, you may give up the ability to receive further software updates.  You may also void your warranty.  But some of us want the ultimate control and it's nice to know that it is possible.  I'm definitely not advocating that everybody roots their device, but I also wanted to lay the steps out there in case anybody was curious so they don't reinvent the wheel.
 
I will keep an eye on the firmware updates and see if I am able to update successfully when the next new one comes out.  I don't suspect there will be any issues, but if there are I'll try unrooting and updated, and if necessary (meaning that process doesn't work) I'll do a firmware reset and see if I can still get the updates (which I suspect I'll be able to do).
 
As an aside, it looks like the bootloader is fully unlocked ( http://www.imagli.com/p/1151505084145803402_2369376095 ) so we should be able to do custom roms with baked-in root, if we really want to.  This is also why I don't think that rooting and then unrooting should prevent me from getting firmware updates.
 
But like I said, I'll be the guinea pig and will report back if rooting prevents you from receiving updates.  Please don't root your device unless you have a good reason to!

I live in Australia and there is a site that was selling it for $789 AUD. A fellow Aussie recommended the site to me, I don't think they ship to the US.
I got mine from https://www.eglobaldigitalcameras.com.au/onkyo-dp-x1-b-portable-high-resolution-digital-audio-player-with-built-in-dac-headphone-amplifier-black.html .
