It's a Windows 10 laptop. Yes, it's for the audio signal to headphones/speakers with a 3.5mm jack.

Is there anyway to convert the signal, without losing quality?

You wouldn’t want to change an already converted analogue signal (from the laptop’s DAC) back to a digital signal just to output an analogue signal with the Mojo again. That’s too much hassle, too much expense, as well as detrimental to the sound.

It would be much easier to try a different USB cable to try and correct for what you’ve reported, or perhaps use an iFi Jitterbug (for RF noise, not jitter with the Mojo), or you can try a different source to feed the Mojo. Something like a Shanling M0 or Hidizs AP80 are small and relatively inexpensive, or there are other portable players that have coaxial or optical out.

Your PC or laptop provides digital out through the USB connector.
Older MacBooks have an optical output in the 3,5mm jack connector, but that feature has been removed a few years back.
Personally I have used the Mojo with coax and micro-USB cable from the HiBy R3 DAP and the coax sounds smoother, the USB sounds more crisp and open to me.

Initially I thoght that this might be due to the HiBy R3 since there is a difference in digital signal that is transmitted by the R3 through the coax cable, where the R3's volume control affects the digital signal, and the USB cable, where it doesn't.
Since then I bought the Meenova Lightning-microUSB cable and did more comparisons which let me conclude that there is a difference in how the Mojo sounds depending on the input used.
I personally prefer the micro-USB

Yes, that’s correct I have old MacBook Pro I got in 2014. It’s has digital out from 3.5mm headphone jack. I am using that with my Mojo.
Too bad they removed it from new MacBook Pro. All the more reason for me to keep my 2014 MacBook Pro.
Also optical cable only support 24/192Khz and that too is dependent on the cable. I have one optical cable that supports 24/192 however the other one with better build quality doesn’t pass 24/192

Hello,

Currently have, wavelength brick v2 "The Brick uses custom code developed by Wavelength Audio to support USB ASYNC mode. The Brick has a very low jitter central clock that runs the entire audio section. The output 16/44.1K of the TDA1543N2 (5% top selected) multibit dac and passive I/V is directly connected to the 12AU7A/ECC82 output tube which in turns drives the reactor follower output for excellent drive and sound.

Maybe some person had mojo and brick v2?

Am I going to regret selling brick and getting mojo?

Mojo used only as DAC together with iCAN SE sound great; iCAN drive HD600 so easy.

How does it sound compared to directly connecting the HD600 to the Mojo?

Exactly my question, is this portable amp any better then mojo’s amp?
I can understand desktop amp replacing it but using another portable amp.
May be it sounds better.

Actually you can't «replace» the Mojo's «amp», since the latter is part of its DAC and can't be bypassed. So all you can do is reamplifying the Mojo's headphone output, which technically doesn't make sense, the less so as the HD 600 is an easy load for it.

Well, I‘d say if it adds a coloration or tonality you like it does make sense for the one who likes it that way.

Therefore the term «technically».

The soundstage is way bigger on iCAN than Mojo, even without 3D activated.

Width or depth?
The one thing about the Chord DACs that impressed me most was the soundstage. When connected to my pretty good stereo (5k amp and custom speakers made by amp producer) the wall of my living room vanished and now I have a Jazz Club, concert hall or church at home, depending on what music I play
Excellent recording required of course....
I really didn‘t think that this was possible.

Actually Mojo doesn’t have an “amp” section, it’s all about the FPGA circuit; I set the line level mode at 1,9V to connect with iCAN.

More width is improved.

I feared that answer

The FPGA is just responsible for the filtering, there's an attached discrete output amplifier stage serving as both line out and headphone out. That's why there's nothing to gain by adding an external amp, since you can't bypass what you consider an inferior amplifier – technically speaking.
Line-level mode is just a volume preset, no hardware reconfiguration.
