Is anyone here able to say if the iBasso D-Zero MK2 would allow me to listen to Spotify/Tidal/Quobuz on my Xperia Z1 Compact?
I know it's a new device, so knowlegable speculation would be almost as welcome as actual confirmation!

 
I received the Ibasso D-Zero MkII today and I confirm it works perfectly with my Galaxy S4 (stock ROM 4.4.2) with native audio (spotify, etc) and also with USB Audio Pro with files up to 96khz.
 
It's a great device to use with phones thanks to it's battery. So draining the phone should not be a problem.
 
I plan to use the line out to use with a Cayin C5 portable amp and Senn HD650 headphones.

@king conan That sounds like a very nice setup. I use the Cayin C5 with my S4 too. I was going to purchase the MkII but went with the microstreamer instead. I now have my eye on a future upgrade to the iBasso PB2 as it as balanced output. Unlike the MkII however, the microstreamer will only work on android 4.4.2 with USB Audio Player Pro.

I tried the D-Zero (Mk1) with my SGS3 and the C5 on my HD600, not much difference at the loudness level I needed. The MkII has an improved amp section so the gap will be even smaller, if not equal or better than the Cayin.

I really appreciate your reply conan, thanks!

I'm certain now tjat this is the device for me.
As soon as I've put enough cash aside, I'm getting one

 

[DanBa]

  thank you for clarifying that, DanBa.
 
what would be the effect, then, of using different players? neutron vs poweramp vs stock.  i know that at least on my last phone's onboard system, i did some a/b/c comparisons, and the music sounded better using neutron than stock or poweramp. 
 
how big would the effect be of using different players when run through a much better external dac/amp?  i'd appreciate your thoughts.
 

 
I have different players, but I don't use different players: from the time being I use USB Audio Player PRO (UAPP) most of the time.
Before USB Audio Recorder PRO / UAPP, Neutron was my preferred music player.
UAPP "boosts the audio experience to the next level above the normal" generic music players (Neutron, Poweramp, ...), at least because there is no 48kHz sample rate conversion.

  also, how does this compare with a dap? i have an ibasso dx90 that sounds very good [i'm looking to see if i can can even better sound without having to spring for an ak240.]  in my dx90 there is a "player" with involves the interface.  how good is THAT player?  [since we know all players are not created equal.]

 
Who knows?
That is one of the issues with DAP. But DAP is an all-in-one system, it is more convenient for a lot of people.
 
Personally, I like to tweak my separate component setup. I can replace individual components over time.
 
My next tweaking step will be the addition of a virtual reality headset for legacy movies, virtual reality movies, concert in a virtual reality way, etc.

Nowadays, we can spend an intimate moment with a musician at work in his studio loft in a virtual reality way by using a Samsung Galaxy Note 4 and a Samsung GearVR headset.

We can go to a giant screen movie theater at anytime, anywhere in a virtual reality way by downloading a movie file into the Galaxy Note 4 and launching  the Oculus Cinema app.
 

 

 

 
"It was better than sitting in a real theater, and immediately made me wonder why I'd ever go to a theater again if I could get my movies this way. When Carmack told me he watched the entire Matrix Trilogy and a full season of Max Headroom in there, I got a bit jealous. It feels like a true killer app for virtual reality."

I have contacted HibyMusic. They have responded to me that a new version 2.0 with new UI is coming next month.
 
Also, DSD256 and multichannel PCM will be supported soon!
 
This will surely beat UAPP.
 
If you're interested in contributing themes to HibyMusic app, please contact:

They're looking for theme artists!

"Exo-Drive cases bring expandable micro-SD card storage to select devices."
"MicroSD, microSDHC, and microSDXC cards are supported. Currently available cards up to 128GB will work. Cards up to 2TB in size are supported, however currently do not exist."

Nice concept for sure, let's see if external microSD via USB OTG were draining the battery like this

Hugo is powered by its own internal batteries, somehow the battery drain of Sony F880 series / ZX1 would go off the chart once we hook it up with Hugo.

Computing devices (i.e. PC, smartphone, ...) & noises:
http://align-centre.hatenablog.com/entry/2014/05/10/233000
 

 
Intentional 4G/3G/2G/WiFi/Bluetooth radio frequency emitters and receivers with a high electronic integration density within a very limited small volume like smartphone should create a lot of EMI/RFI noises.
 
 
A solution: moving the DAC/amp from the noisy Android phone
 

 
"In the second design, the external audio peripheral C can be designed for higher audio quality and greater power output without impacting the cost of the basic mass market Android device B. Yes, it is a more expensive design, but the cost is absorbed only by those who want it.
Mobile devices are notorious for having high-density circuit boards, which can result in more opportunities for crosstalk that degrades adjacent analog signals. Digital communication is less susceptible to noise, so moving the DAC from the Android device A to an external circuit board C allows the final analog stages to be physically and electrically isolated from the dense and noisy circuit board, resulting in higher fidelity audio." [Android audio team]
http://source.android.com/devices/audio/usb.html
 
 
A further solution: no 5V voltage bus power line from the noisy Android phone (cleaner 5V power from an external 5V battery, no EMI/RFI noise issued by the Android phone via the 5V Vbus power line, no cross contamination of the USB data lines by the USB Vbus power line)

"Qantas Group Executive, Brand, Marketing & Corporate Affairs Olivia Wirth said the technology will open up a new world of lounge and in-flight entertainment for customers, as well as give Qantas a powerful way to preview destinations and experiences.

“From an in-flight entertainment perspective, it’s an industry first.

I'm wondering if there's a hi-fi grade OTG USB cable for Android phones and Geek Out.
I saw one of them on this forum but I don't know where to buy it.
There are a bunch of them for normal tablets and ipads, of course. I'm looking for a one with socket so I can use it with my Geek Out.
