I totally agree.  The cabling with any CCK or Lightning-to-USB is not portable-friendly.  The best I've been able to do is a 30-pin iPhone 4 (or presumably 4s) with CCK (which is a plastic brick with no cable) to a short USB A to mini USB and then to the microStreamer which has headphone out.  Despite what has been said by HRT directly, the microStreamer does put out clean audio at CD-quality rates, and the solution is definitely portable -- in fact, in terms of overall 3D volume, I don't know of a solution that is smaller.  The 30-pin CCK lengthens the iPhone some, though, and there is that silly USB cable.  If I find a short flexible 4-inch USB cable, though, velcro the microStreamer to the back of the iPhone, and put it in a longish case, it would definitely work for me as a pocketable solution, especially given its thinness.

The CCK/Lightning to USB adapter actually implements the rest of the USB host interface required by non-Apple certified DACs - remember that the CCK was originally designed to allow direct connection via USB with digital cameras. The iDevices never had a full USB host interface on either the 30 pin or Lightning connectors.

 

I don't suppose it would be possible for a custom cable job to be able to perform that task while being shorter and easier to work into a small portable rig? I  figure it's a crapshoot but it'd be worth investigating, that could potentially open up new doors for compact, clean-looking portable rigs

ALO Audio posted a vid with an iphone5 with ios7 connected to their international via the cck on facebook.

great stuff!

What is the purpose of using a passive USB hub between the iDevice and the DAC? I thought it was because the iDevice draws too much power through USB for some DACs, but wouldn't that require a powered hub to fix?

post #80 of 440

Some hubs seem to alter the current draw of the DAC, or otherwise seem to "hide" the requested power from the iDevice through the CCK or Lightning-to-USB adapter.  Otherwise, you will get a message that "the connected USB device draws too much power."  I don't know how to measure what is happening or know the exact details.   But I've got a passive hub that works with an E17.

And not all DAC/amps need the powered hub.  My Apex and Leckerton worked fine without.

My DAC's manual says the following:

 

Quote:
Warning: Connect this DAC via an USB HUB, or via USB interface on the front panel of a desktop computer, might seriously degrade the sound quality, due to more interference!

 

It's a Chinese DAC so the English isn't great, but do USB hubs really have interference? I kind of get the part about the front panel connection, as analogue connections like headphone and microphone jacks pick up a lot of noise from the components inside the case on their way to the front panel. Didn't know digital data like USB could be affected though.

post #83 of 440

If the only thing connected to the hub is the DAC, and the host is an iPhone or iPad, I would doubt a hub introduces interference.  I think the warning has more to do with multiple peripherals (mice, portable hard drives and the like) in a PC environment.

It works with my iPhone 4S! I was searching for some type of digital out for the iPhone. Now problem solved! Although I have been playing this from the iPad 3, the iPhone is more convenient (and has more of my music on it). Now so long as Apple doesn't mess this up!

So... do I still need to buy the Centrance HiFiM8 (iPhone version) or can I now instead buy the "generic" version (USB + ToshLink) M8-LX ??

Sounds like you could just get the USB version :)

 

Although if the cost difference isn't big for you, think about getting the iPhone version just in case Apple decides to drop the feature.

Hi guys i just want to understand one thing. I have an Iphone 4 with iOS7 and I am looking for the microstreamer and the Audioquest Dragonfly. Do they work just with the CCK without a powered hub?

 

Thanks.

Frankly I don't know. Prior to iOS 7 I ran a Fiio E7 with my iPad 3 through the CCK without a powered hub, all I had to do was to turn off the USB charge function and run this with the inboard battery and it worked fine. If you had the USB charge enabled, however, you got the "low power" reading. I assume it would bethe same with the iPhone. So long as the. Dragonfly etc has a non USB charge function, I would assume that it wouldn't need a powered hub. However this stuff is confusing. I now mainly use an Aune T1 hybrid dac/amp, which is a plug in desktop unit with a tube dac. The Aune thread gurus assure me that the dac doesn't draw power from the USB. Nevertheless you get the "low power" reading on the iOS equipment unless you use a powered hub. No problem for me, because my station is a desktop one but you would want to try out the dac of your choice to make sure it works.

I've tried a CEntrance HiFi-M8 XL today on IPad mini IOS 6.1.2 with the Lightning CCK, and Android phone with an OTG to USB adaptor, using a random USB A - USB B cable, both are not working. The IPad mini shows not supported and Android shows nothing. I played music with the original audio player from the system. Before I've tried the same set-up with Apex Glacier and it worked flawlessly. I am not sure but those who wants to use XL version with idevice and android system please check again.

 

So Audioquest Butterfly checked O.K. with IOS7 and CCK right?

post #90 of 440

I thought iPad+CCK already worked before iOS7? But upgrade to iOS7 and see what happens. It should work, according to what everyone has been reporting.
