Yep, good idea,  but I'vnt the propers tools and skills.

Double Helix Cables may be willing. He said it would be a difficult modification.

Probably depends on which side is the spacial auth chip but I think its on the Lighting side. So you have to find the cables and solder them on a male MiniUSB-B.

Yeah I've heard the M100s are quite bassy. Whereas for my PSB M4U 1s high gain with max boost is just about enough (although still not quite enough in the sub-bass region without digital EQ).

I don't want a non-angled like this one > http://forzaaudioworks.com/en/product.php?id_product=53 as it's a pain for an every day use (in the pocket).

Any suggestion ? (I'm in France)

We should suggest to JDS Labs to make custom LOD's to go with their products, at a price around 30 to 50 $, not more.
When you ask them for the C5D, they answer Apple CCK ;-( , witch is useless to have a compact rig.

Thanks (and excuse my poor american/english !).

According to Apple, the CCK circuitry in not available to any third-party developers. So, even Apple MFi developers and manufacturers are unable to produce the cable you desire.

@OlivB, if you truly need a nomad (sans CCK) setup, you'd have to wait for when John gets MFi certified from Apple, and in which case you might need to send the C5D back to him to update the logic board with new hardware, and then you'd be able to use cables like the one you linked to us from Forza Audio.

A logic update is not possible. An Apple MFi device requires additional hardware authentication, meaning such a change would demand a new design.

Yikes, that's even worse than i thought.
John, if in any case you'd get MFi approved, would we be able to replace our existing units with the new MFi design?

Sorry, too much speculation to give any useful info. If/when JDS Labs has MFi authorization, we'll shift our development plans accordingly. For now, we must assume that path is not open.

@AzrinRain Yep, I truly whant a nomal setup. I come to C5D because of it's quality AND for a nomad use !

to @AzrinRain and @jseaber 

What a debate ! I'm not sure to understand every thing... Isn't it just a matter of connections and bits of cables ? To replace a CCK whitch is just made of plastic, connectors and wires, why can't it be just appropriate connectors and bits of cable ?

If there is an digital sound signal through the 30 pins connection of my Ipod, it should be able to be "read" by the C5D through the mini-Usb A connector, like it does when I connect the CD5 to my Macbook ?

No ?

@OlivB, not really. Google up 'Camera Connection Kit Teardown' and you'll see that there's an entire PCB layout there with chips which names and functions escape me (which is why the CCK is essential in the first place). As a side note, the Lightning connector has a built-in authenticator chip which requires approval and parts from Apple to be able to perform a 'handshake' between the cable and iOS device.
And if John does get MFi certification, slapping these chips in the existing PCB design is not possible. An entirely new layout has to be made from the ground up, and more research is needed on which components go best in the signal path, while still retaining the existing SQ.

And nope, the iPod doesn't work the same as a Mac.

How ! Thanks very much !

That means that using this > http://www.aloaudio.com/cables/portable/digital/sxc-24-30-pin-to-usb-mini-a

or this > http://forzaaudioworks.com/en/product.php?id_product=53

won't work propely with the C5D ?

These do NOT work

You make me saving money.

So what are they for ? Is it a scam, even if they says "For connecting your Apple device (with digital out and 30-pin dock connector) to portable DACs like Cypher Labs Algorythm Solo (CLAS) or Fostex HP-P1"... ?

Completely different think! C5d is not a MFi. Certified apple dac etc...
