My experience in carrying the O2 around is that when i reach for something else in the bag, i tend to accidentally adjust the volume knob (with little resistance), and it does tend to annoy me at times. The C5D's volume adjustment makes it nearly impossible to do that. You need a degree of...

Okay, here goes a weird request. Can anyone try out if the DAC section works via USB from a PS3 / PS4?   I'd love to try it out, but unfortunately my PS3 has the YLOD.

Ah, yes. That, too. The O2 + ODAC combo is a great, transparent desktop DAC setup, and if you need a portable DAC setup with sound characteristics nearing that of the O2 + ODAC, the C5D is a good way to go. The only caveat is that you need extra cables (i think the shortest possible route from...

  To (hopefully) answer your query: 1. Using an external DAC to bypass the internal one produces a completely different sound signature, rather than just cleaner signal per se. If you want a clean(er) signal while retaining most of your iDevice's sound characteristics, an amp like the C5...

Give @miceblue's suggestion a try. (link here)     Mods, sorry for the back-to-back posting. Wasn't quite sure how to add more quotes to an already published post.

I'm a little curious as to what would you like to achieve with said setup? I'm made to understand that at past 2pm (on the Roxanne's bass dial), it's much more than other JH models (even JH16), thus [potentially] negating the use of the bass boost. Nevertheless, i'm saving up for the Roxanne...

John, based by the way @Vemon's question was answered, i had the impression it was. Was the bass boost intentionally configured that way (low>high>mid), or was it supposed to be naturally progressive (low>mid>high)?

  Ah! That explains why my bass boost switch is being funny. Thanks for the clarification, John!

Oh, cool! Have fun then!

Your iPod Touch will not go up to iOS 7, hence the DAC option via CCK will not be available for it. But your iPhone 4 will be fully capable.

  @OlivB oh, don't worry about the strength. You could literally do this:     I think you could just get a shorter USB to USB mini A, and be done with. Probably best to get one with a ferrite bead.     EDIT: Hey, wait a minute. All this while i failed to ask you a very important...

  Haha, the beauty of that engraving also blinded people from looking at my answer XD

    @OlivB Nope, it's not a scam. Earlier on i mentioned about MFi devices and how they have additional chips and approval from Apple. The CLAS and the HP-P1 are examples of said MFi devices, being able to forgo the CCK + supplied USB cable in favor of something like this:        ...

@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...

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?

@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...

  When i heard people mention that the C5D is like a baby O2, I was quite thrilled! To be honest, carrying the O2 around (it's big!) was not really working for me. The C5D is something i'm able to strap to my iPod, and still be able to pocket it.

@metaldood  My portable setup: iPod Video (5G) > LOD > C5D (amp) > SE 530. Also, iPhone 4S > CCK > USB C5D > SE 530. At home and work: MacBook Pro > USB C5D > O2 amp > SE 530 or Denon D-2000.   @dbdynsty25 I use high gain, low volume, bass boost off.

Hello everyone, been lurking around for a very long time now, and thanks to your recommendations, i decided to jump the gun and get a C5D! A great portable amp + DAC for those who love the O2 sound sig.
