Hugo 2 will have its own poly device, been confirmed by Chord.

I wonder whether it will be possible to connect poly to hugo 2 via microusb extenders, until the proprietary solution arrives. I cannot imagine why not, save for an intentional restriction by design.

"There are two problems that USB has against toslink - and one benefit. The benefit is that timing comes from Mojo - but with toslink the incoming data has to be re-timed via the digital phase lock loop (DPLL) and this is not quite as good - but you will only hear the difference via a careful AB test, so it's in practice insignificant.

The downside with USB is the common ground connection."
 
But Rob, what if none of my electrical devices are grounded? In my room the only AC-powerplug there is in my room is a 2-pin-no-ground, so my computer and everything is not-grounded. So that means there is no common ground (right?), and this should mean that there is no downside for me with using USB, right?
Or can there be "internal grounds" (whatever that is?) within electrical systems even if there is absolutely no connection to any "real" Earth/ground? 
 
I would really appreciate an answer, as I'm wondering if a optical toslink cable from my onboard RealtekALC1150 to my Mojo will be more "musical" than the usb cable I have from my computer to my Mojo currenty.... Thanks!
 
EDIT: But yes litterally, my computer is 100% ungrounded... Wonder if it's a problem. Have no apparant problems and I have used it like this for 2 years now.

I think this will also apply to the Hugo 2 http://www.head-fi.org/t/831347/chord-electronics-poly-advanced-wireless-microsd-module-for-mojo-specs-in-1st-post/1005#post_13199922

I use optical from my desktop, and the sound from the Mojo is very clean and precise.
If i use usb from my desktop, I can occasionally hear short bursts of low level electrical noise (a bit like the sound of a record stylus being dragged 1mm across a record) during very quiet passages - however just as Rob Watts predicts in his posts, this electrical noise makes the music sound slightly brighter.
 
Mostly I stick with optical, but occasionally I like to try usb for some albums.
You will only find out if you prefer optical by trying it, and all you need is a $5 cable - so it will not be an expensive experiment.

Hi, may I ask how you get optical out of a desktop?

I presume that was a joke.

No, special sound card perhaps?

Nothing special - it is a 10 year old Asus P6T SE motherboard, from the days when optical came as a standard output socket.

has anyone used AudioQuest Forest USB cable to connect Mojo with the laptop.
I am planning to get one so wanted to know if any one has something good or bad to say about it.

 

[Zojokkeli]

   
Quite possibly. May I ask your serial number range?

 
My serial number is in the 38XXX range.

It is a very "stiff" cable, keep that in mind.

 

[dreambass]

Mojo seems a maybe it will maybe it won't, what if device reading through this. ( hiss hum cable charging etc etc)

Thanks a lot for info. Don't want the cable to be stiff.
Any suggestion for good USB cable for MOJO

Should I go for the Mojo + Poly for portable use or get the Hugo 2?
