Chord Mojo(1) DAC-amp ☆★►FAQ in 3rd post!◄★☆

[Xacxac]

All ios devices have problem playing DSD256 as well. DSD128 is fine. I'd put my bet on inefficient DSD processing.

But then, I don't hear any difference between PCM384 & DSD256. I almost never listen to DSD material.

Edit: DSD256 bitrate is significantly lower than theoretical & practical USB 2.0 transfer speed.

Is there any portable player have a sound quality of chord mojo? I do not want to carry 2 things other than phone (don't want to use phone for the music since music play drains the battery).

 
Difficult question to answer with many differing opinions.
What would you be looking for in this DAP?

  I bought the Audioquest Jitterbug when I bought the Dragonfly Red. If I end up keeping the Mojo over Red, will the Jitterbug be useless/redundant to the Mojo...or should I keep it?
 
(I think I'll get about $45 back or so if I return)

 
 

Redundant. Because of the way Rob's DACs work he says they are all immune to jitter, this includes the Mojo. Some have purchased the Jitterbug with the Mojo and have reported no change in sound. Best to test for yourself if you have one.

Edit: This is copied from (of course) the third post in this thread. There is SO MUCH info there people.
 

The Jitterbug is also supposed to clean up the USB power-lines.  And, while the Mojo is supposed to be immune to jitter (I'm certainly not suggesting otherwise), it's seemingly quite sensitive to noise over USB (and I believe Rob has stated a preference for the optical input somewhere back in this thread).
 
That said, I picked up a Jitterbug when I grabbed my Dragonfly Red ... and I can't tell any difference using it with either that or the Mojo.
 
It does seem to make a difference with my Stockholm V2 though.

I have to say that after having the Wyrd 4 Sound Recovery feeding the Mojo its digital stream; there is a noticeable immediacy with slightly more separation noted during my critical listening sessions. I just love it!

Hard to say if there is "any" portable player that beats the Chord Mojo, but I'm inclined to doubt it.
 
I will say that, in my opinion, it comfortably beats the DP-X1 as well as the entire line of AK players (though I've not  heard the copper version of the 380).
 
I have various configurations for music listening when I am on the go/traveling, ranging from just the phone and one set of IEMs (I often take the Apple Smart Battery case - which I only use to keep the phone at full charge while listening to music during travel, it comes off once I arrive), all the way to taking an AK120 as a transport and the Mojo.

DAVE has galvanic isolation which eliminates noise over USB, although it consumes power and therefore not suitable for portable devices like the Mojo.

At first I was going to say I am not sure whether people would bring a US$10,000 DAC with them on the go, but considering the price of watches that people wear, I think that's acceptable.

Yeah and some of those people use the earbuds that came with their iPhones.

 

[audi0nick128]

There is a way to add galvanic isolation to Mojo.

It doesn't even need external power.... Wouldn't call it very portable... And the price is rather high for a USB decrapyfier, but I would love to give it a try.

Cheers

Who knows, maybe they are using the Dave to drive their iPhone earbuds...

Yeah, just explaining why Chord doesn't have it for their portable devices, although the thought of the DAVE in a portable setup certainly is rather funny for the size. Certainly the AK380Cu and Cu amp, plus perhaps some Noble prestige IEMs is close to the price range though.

That gets it's power from the USB port on the computer I believe, therefore not suitable for portable where battery life is important as well. AFAIK galvanic isolation requires a power source.

Dave is the only way to beat the best DAP in the portable world. The device and the source may not be very portable, but who are we to say anything when people think AK380Cu+Amp is?

 

[audi0nick128]

Yeah ok I see that's a factor
Just read it this morning at work and got curious.
I don't know if it would even work with a mobile device.
I may just ask the manufacturer...

 

[jmills8]

Dave looks a lot better than the AK380 CU.
