Schiit Decrapifier released - USB power isolator

[Jimmy101]

No, there are different generations of the USB card inside the Schiit DACs.

The first two Schiit DACs I purchased both came with USB gen 2. I purchased a Bifrost in February and a Gungnir in August of last year. These both came with USB gen 2. I purchased a Yggdrasil, and this is the only DAC from Schiit that comes with USB gen 3. I sold my Bifrost (Uber upgraded to Multibit) and recently purchased an original Bifrost (4399 upgraded to 4490 - sorry, I'm a bit of a collector) and it came with the older USB gen 1.

That's why I asked the question - which generation of USB card do you have in your Schiit DAC? Unless you see the too much power issue when plugged directly into the DAC, my guess is you have USB gen 1. I heard it click, but I never got sound to come through the DAC.

I get the too much power. I really think it's the adapter. I do get connection sometimes but it's less and less now. I woggled it around a little bit while it did have a connection and it cut out. Plus I get the message "this accessory is not supported by this iPhone " even when the adapter is not plugged into anything. New adapter will be here tomorrow so I'll know then.

Dang - I forgot to look at my Amazon account to tell you which cable it was. Hopefully your new cable does solve the issue!

Mystery solved. It was the adapter. Nee one makes immediate connection

Nice! congratulations on finding the problem. I'm glad it was just an adapter.

Ok, silly question. Could not I just use the standard lightning to USB cable and then a USB female-to-female adapter like this one http://www.ebay.com/itm/USB-3-0-Type-A-Female-to-Female-Adapter-Coupler-Gender-Changer-Connector-NEW-/331719054401 ?
 
Or that specific adapter is necessary to output the digital audio from the iPhone?

TL;DR - I think the answer is no.
 
While I cannot find anything to validate, my basic understanding (from trial and error) is the CCK basically instructs the iDevice to start sending data (video, audio) out through the USB connection. While a USB hub (and gender bender) would in essence connect a bunch of devices, I have not, without CCK, been able to establish a connection between any iDevice and any DAC.
 
So I think CCK instructs iPhone to bypass internal speaker/DAC and send audio out instead via the USB connection. Without CCK, iPhone will not try to push A/V data through the digital USB connection.

Thank you very much. So this is the way to tell the iPhone to push the samples to the DAC. And this would work also from the stock music app? Great!

Yes - stock music app sounds fantastic 

 
I also use Tidal, and plan to try Onkyo HF for higher resolution music (i.e. paid-for downloads).

Also great news. My wife wanted to know how to feed the iPhone music directly to my new Gustard X20U. Which model of CCK do you use?

Not sure - whatever was recommended on Amazon. I did see someone in a thread recently who bought a cheap CCK and was having issues. It's probably worth the extra couple of dollars to just get the standard CCK.
 
I have a really old iPad, so it has the older CCK. My newer iPhone6+ works just fine too. The only time I have an issue (and the Wyrd comes in handy) is when the DAC draws too much power. All the Schiit DACs do this. But I have no such issues with Chord Mojo. Best of luck!

I know this thread hasn't been updated in a bit, but I have a question about USB cables with the Wyrd. I have a PYST cable going to my Gumby, but a pretty standard no-name USB cable going from my source into the Wyrd. That cable matters less, right? It's more important to have a nice cable take the Wyrd's output to my DAC. At least, that's what I'm thinking to save myself from buying another cable haha. What do you think?

 

[oAmadeuso]

That's what I did and seems fine. Better to use the best cable for after the signals been cleaned.

I'm assuming this is for USB powered only DACs? Would the Modi 2 not see any benefit from this because it is mostly powered by its own personal power supply?

No, there is still a benefit to using the Wyrd with powered DACs. I've used it with the Bifrost Multibit and Gungnir Multibit.
