Onkyo HF player does not have an option to change the buffer size. 
 
I made a conclusion, based on responses (THANK YOU) that ipad/iphone+Onkyo HF combo is not able to supply Mojo with stable 5.6 and 11.2 MHz data to decode.

Where are you guys getting that 8 ensembles in one bit album? I get brief cut outs with double rate DSD on my iPhone 6 so I'm sure it would cut out even more with quad. Can anyone with an iPhone 6s test if they get the same cutouts on double or quad rate DSD?

There was a coupon in the Mojo box when I bought it. There was a reference to the site to download it from (free).
And for quad rate - I tested it today, there are even more cutouts

  I've tried 3 micro usb cables.  Tried both usb ports on 2 macbook pros.  I went to get a camera connection kit just now and it works using the micro usb that came in the box, so its not the cable or the mojo.  It's something with the settings I think.  At least it's not the mojo.

Well, my experience is that it just works. I use mine all the time on my iMac and it just connects and works. I don't remember having to change any settings. Changing the MIDI settings just keeps OS X from upsampling the signal it sends to the Mojo.
 
So, I got out my Macbook Pro, Model 11,1 running OS X Version 10.11.4 which I have never used the Mojo with, and connected it. Turned the Mojo on and it just worked, upsampling to 768kHz because the MIDI settings default to the highest the connected device will take. Turn the Mojo off and the sound shifts back to the internal speakers.
 
Sorry, but I have no idea what else you can try.

I hvave deletrd all my dsd files and replaced them with cd 16/44.1 flac rips. Flac sounds better on chord dacs than dsd. Save your hard drive space, dsd isn't an improvement and actually just wastes space

No problem playing DSD on my iPhone SE and iPad Air 2. But then my devices are 'clean' (well-maintained).

Try to close all browser tabs, force close background apps, etc. If that doesn't help, increasing buffer size won't help much. All modern iOS devices have fast storage (check Anandtech). I think the bottleneck is processing power or software optimization. I suspect Onkyo HF doesn't optimized as the latest iPhones are more powerful than most android phones.

Have you tried double or quad rate DSD though? No one is having problems with single rate DSD. I'm just curious if the 6s or iPad Pros have the extra speed necessary to power through whatever is causing double and quad rate DSD's to skip.

How costly is quad dsd? How much space does it take opposed to a flac file? Has anyone heard it on mojo vs flac?

q-dsd is much more space consuming for little gains over flac, i have same songs on flac and d-dsd and q-dsd and only get minor refinements in the music

 

[Jangir]

For the same song in DSD64 - 113Mb, DSD128 - 226Mb, DSD256 - 552Mb. Unfortunately, I do not have FLAC version to compare the size.

It takes up A LOT of space. There really aren't a lot of quad rate stuff out there, just random things like that 8 Ensembles in 1 Bit.

The one double rate DSD album I have is Tea for the Tillerman and that takes up around 3gb. I personally think it sounds amazing and is the best I've heard the album.

Comparing a lot of these DSD albums to flac is useless most of the time because the DSD is usually a different master. One thing most of these DSD albums have going for them though is great dynamic range. People can crap on DSD all they want but it's simply the best sounding version of many of my favorite albums.

Have you guys tried different dsd formats on mojo? I haven't tried abing music formats in years. Maybe now, I'd be able to hear a difference between them with mojo? Last time I heard a difference was between <320 to alac, flac, or to 320.

Great album for demonstrating the Mojo's capabilities. Any issues will most likely be on the transport used, the power of the CPU of the device. Remember the Mojo just deals with the data fed into it, provision of that data will be down to the source ie iPhone, Android phone or DAP.
 
This has got me thinking, I wonder if the forthcoming SD attachment will handle DSD 11.2Mkz files (only asking out of interest) 

 

[warrior1975]

I should check that out. I totally forgot it was included in my childish Xmas level excitement.

These are the connectors of Black Dragon coax cable from Moon Audio.



These are much better than connectors of EBay cable



I think you could ask @Peterek to make your cable with more options (cable, sleeve color ...)

Mojo arrived far earlier than expected, waiting for my USB adapter to come in the morning. What apps are recommended with iPhone? I'm seeing Onkyo quite a bit.
