  I did a quick search and found nothing on the subject.
 
Has anyone rooted their unit and used viper4android?  

I did as soon as I got my DP-X1.
One thing to note - The driver does stop processing after some random amount of time, which is "fixed" by rebooting.

Set the amp gain to Low2 should help. Most likely the amp is too powerful for you iem

Thanks a lot @addyg!!!
 
That was it! I set the amp gain to Low and that did help. Sound is excellent now, also with Tidal.
 
By the way: I do not experience any interruptions when playing Tidal form microSDXC card (HIFI Abo, best quality setting possible) - this should be dependant on the microSDXC used. I am using the SanDisk Ultra 200 GB Class 10 (read: 90mb/second).

I use the Samsung 256GB 95MB/s EVO Select Micro SDXC Memory Card (MB-ME256DA/AM) which is even faster. 
My speeds vary, but with the the Samsung and a reader I get speeds around 55-60MB/s. With a 200GB SanDisk card I get only 3-5MB/s.

I'm using the SanDisk Ultra 128 GB Class 10 card.  I'm only getting read 38MB/s | write 15MB/s  on the DP-X1. Anyone else able to play offline albums with out the random skips?

Is it possible to stream Tidal Masters (MQA) on the DP-X1?  I have both but cannot see the "Masters" in the "What's New" list.  Is there a setting I have wrong?

Tidal has yet to make MQA available in mobile apps.

Master-quality albums and tracks will be available on mobile and web application at a later date.

You asked for it:
 
In order to get music on your DAP fast, choose a good card for writing speed (or be patient with your current card)

This will also make a significant difference to the player s internal function too:

 

Spoiler: Warning: Spoiler!

There are three different standards for speed, and you may see more than one on a card. The original speed marking was a number inside the letter C (middle in the image below). The number denoted the minimum sustained write speed, so a ‘Class 6’ card would be capable of writing at 6MB/s – that’s six megabytes per second. That's a sequential write speed, so it only applies when writing large amounts of data (such as when copying large music files) in sequential memory cells.

Most Class 10 microSD cards are capable of much more than the minimum of 10MB/s write speed. The SanDisk 200GB cards can do a theoretical 30MB per second on long sequential files. On shorter ones like album art youre going to see lower speeds.

Now, for even better speed on newer cards, this is where the UHS system comes in. It stands for Ultra High Speed, and uses a number in the letter U to denote the class. A UHS class 1 card writes at a minimum of 10MB/s and a UHS class 3 card writes at a minimum of 30MB/s. So basically the U number is a factor of 10 better than the C number, which also maxes out at C10.



 
 

You may also see UHS-I or UHS-II on the card. This tells you which technology the card uses. The UHS-I ‘bus’ can operate at up to 104MB/s, while the UHS-II bus can transfer data at up to 312MB/s. This doesn’t mean the card will read and write at those speeds, only the maximums. At the moment I don’t know of any DAPs that actually take advantage of the UHS-II connections on these cards… but thats fine, we’re worried about writing to them from your Mac, not your DAP. So UHSII makes a difference. You DAP can read slowly - thats fine:

 



 
 

 

3… Choose a good card reader (writer) and use that instead of your DAP for big syncs:

Just like the cards themselves, the readers make a difference. Your DAP by itself is not a super-speed card writer. Don’t expect much over 2.5Megabytes per second using your DAP, and in some cases if it’s also doing other things (like emulating/masquerading as a disk using software) you may see a lot less. So a 90MB/s card in your FiiO X5 is basically trying to squeeze all that data through the X5 emulation software which can do 3MB/s if the planets are aligned or a horrific .1MB/s if its busy.

 

So, take out the middleman and plug the memory card into a good, fast reader thats connected to your Mac using good, fast USB 3.0! If your Mac is older and only has USB 2.0 ports, theyre going to max out at 60MB/s vs USB 3.0 at  640MB/s. Make sure to plug the reader into a USB 3.0 port directly on your Mac - no hubs, please.

 

SDCard Reader:

I recommend the Lexar Professional Workflow UR2 Three-slot microSDHC/microSDXC UHS-II USB 3.0 Reader - LRWUR2TBNA which is on Amazon for around $40

 

SDCard:

I recommend the Samsung 256GB 95MB/s EVO Select Micro SDXC Memory Card (MB-ME256DA/AM) card available on Amazon for $199

 

 

All these things together help make things faster. You’ll never get the theoretical maximum (See the “Up to” text) since Dapper is reading, and writing files over the USB connection to the card you are using, but if you get the best reader, best card and USB 3.0 your transfers will be able to use the added speed in order to help all the operations and improve you speed dramatically - our demo video below uses the best of the best on freshly formatted cards.

 

My speeds vary, but with the recommended cards and a reader I get speeds around 55-60MB/s. With a 200GB SanDisk card I get only 3-5MB/s. This totally makes sense since the SanDisk is UHS1, and the Samsung is UHS3 - 3x faster

One Tidal stutter, check the version 1.9.1.
It's old, but it sound better and there is no delay offline/online play.

With regards to other apps using the Onkyo hardware fully:

As per Onkyo support: 

Is there any way to check is the dual DAC in use or not while plaing any song. In stock player and any other aplication? I mean that even if you use standart output with ankther player no one can say that Sabre DAC is inolved in process of decoding.

Is there virus on this link? The phone has crazy pop ups

2.5 balance is dual dac. Unless your app cannot make a sound through 2.5 balance jack.

I don't understand for over a year still some people asking if it use Sabre dac / use dual Sabre dac.

It is quite clear this CPU is without GSM and this Android is tablet version instead of a phone version.

Even the pcb design of separated board for Sabre dac + amp you cannot pass these components.

I don't see any ground for the questioning.

It has nothing to do with it being GSM or not. There is a Snapdragon chipset running the OS, and Snapdragon chipsets have an integrated DAC. No one but the manufacturer can say for sure if the integrated DAC is completely disabled. I wish we knew that answer.

Yes, almost all android board will have integrated DAC. Unless manufacturer stated (like how V20 disable snapdragon astiq dac, and even then, many 3rd party app cannot fully utilize its quad dac to fullest ability. 3rd party can only use one dac, with android own interface, which downsample the music), we don't know if there is any routing done thru the integrated DAC. The only way to be sure is to disassemble X1 / X1A and see if its integrated DAC still around or not.
 
This is general android issue. I just found out that Axon 7 smartphone which have its AKM DAC have same issue, whereby only its own native app can utilize its AKM DAC fully. Other 3rd party app downsample and use the integrated DAC
