jRiver MC + MOJO
It just doesn't change/adjust sampling rate.


MOJO works straight away with VOX though.
 
Please, can someone guide me how to set it?
 
cheers!
 
all sorted now.

Sure!
1)The Wyrd4Sound Recovery helps to clean and re-clock the digital stream being fed to the Mojo with the use of a Femto clock. I find the Recovery to add a bit of immediacy to the leading edges in my music.

Very nice desktop class portable rig, but I thought the MOJO is async with almost non-existent jitter, so it would deal with what this thing is supposed to do ?
Again it must be additive in some way from the source material adding some kind of perceived "zing" to the music (?)

Thank you! You might be right about the Recovery adding a perceived something. According to John from DAR Audio it adds "jump" factor.

Not with all sources or DACs is what he mentions. The worse the input or the DAC better the Recovery does its job. :wink:

Interesting that you notice a difference as Rob has pointed out in detail why his DACs are immune to jitter and that such jitter removal gear is completely unnecessary with the Mojo. I imagine there is some other cleanup happening here. Curious to know precisely what you hear the Recovery doing to the sound. Not debating what you hear, just curious.

My Mojo is noisy while charging...
oh damn it. 
:frowning2:
 
from Chord:
"The charging noise that you are hearing is completely normal and nothing to worry about at all. All of our Mojo units emit this sound.
What you have been reading about is a completely different issue which effected a very very small number of units back when Mojo was first released. The noise was not related to charging, it was down to an out of tolerance resistor that caused a hissing noise when no audio was playing through the headphones."

For those of you in the UK who are thinking about using Moon Audio. I ordered an AK to Mojo Toslink Form Fit cable on Monday and it arrived Thursday morning.
 
I took the Fedex International Priority option which cost $28 and include great tracking info
 
Moon Audio service highly recommended!

Quick question....


When Mojo is fully charged the led should turn off, right?


it's been 5h and still on, not blinking though.
I'm using 2A charger.
correct

*****************************
If you allow me, I am also curious about what is heard.
 
I have been interested in such kind of Noise/jitter removals or USB galvanic's isolators since my desktop computer is quite noisy.
After reading quite a lot at a scientific/measurement point of  view it appears that those equipment add more distorsion than they remove.
 
Now at a sounding point of view what they had may be pleasant such as tube amps for example. That is the reason why I am also interested in knowing what they bring for sound.
 
Regarding jitter/noise removal, witjout entering into details, please note that there are several kind of noises/jitters taking place at:
- ADC level (before CD/ digital files )
- source level (DAP/laptops/Phones,etc)
- transport level ( cables/ioutside interferences IEM)
- DAC level.
Those USB purifiers may improve power noise, output/input impedance, clocking but they can not remove ADC or source level noises.
 
You may improve noise/jitter at transport level by using:
- optical fiber TOSLINK
- coaxial shielded 75Ohms S/PDIF
- USB with ferrrite/chokes .
 
Indeed it is a vast and controversial subject As Relic wrote I am not putting in doubt whatever audio benefits some may heard.
Mysellf I tend to prefer sound from USB vs Optical despite what Chord explained.

Welp, thats my Mojo delivered. Why oh why does it require ten hours charging, I'm too impatient! Haha. I will just have to wait. Really looking forward to hearing this little bit of kit.
