Interesting. I always assumed that since the file remains digital until it's processed by a DAC, then it's sound is unaltered regardless of source, and therefore would sound identical. i guess I was wrong. This could turn into an endless rabbit hole of marginal gains huh?

 

[jwbrent]

Pretty much. I don't see why the full un-folding can't take place natively in the Tidal App.

Agreed.

Yes, ideally that should be the case. But some of us here have indeed observed differences between 2 transports feeding the Mojo using the same mode.
 
For example, I heard a difference between Fiio X3ii and Soundaware M1Pro, both feeding Mojo via co-axial, with the Mojo sounding more transparent and clearer, when fed by the M1Pro.
 
And some have heard a differences between, 2 different models of Astel&Kern DAPs, both feeding Mojo via optical.
 
This has remained/will always remain a very debatable topic. After many debates, we reached a point in this thread, where both party is happy to stick to their beliefs, while letting the other party stick to their's.  A co-existence, if you will.

Agreed.

Agreed but my understanding now is the original master Tidal is using for MQA are 24/96, so it's sent in 24/48 MQA and Tidal App decodes once getting 24/96 and theorically we are not losing anything. MQA Hardware decoding inside DAC would be worth if original fial is 24/192 or higher or want to make Tidal bypass decoding to DAC.
 
By now I love re-listen those albums in 24/96 with Mojo/HD600 - I am really enjoining.

EagleWings Ah. Apologies for being late to the party!

Their deal on the Focal Elear is tempting as well.

AFAIK Mojo has only one amplification stage. Therefore both jacks are sharing the same voltage (Outputs are in parallel).

Correct. One output stage and, in fact, the two outputs are wired together, so they are exactly the same.

 
So, both 3.5mm jacks when the unit is in line out mode, are putting out the same (as in KVL) level of output, 3V (default), but the currents are split in halves (thinking like the KCL)?
 
In other words, like you can drive two headphones from these 2 jacks out the same line out, when say both are driving two separate amplifiers?  (not that you ever want to)

Correct.

You'll find those who disagree are staunchly opposed to performing a proper, witnessed, controlled test to demonstrate the merit in their opposing view.

So, again, I'm not an engineer, but my understanding would be that the same output is available to each output (L or R).  If I plug a headphone into the L output, I will get a certain voltage for a given volume setting.  If I plug a second same headphone into the R output, the impedance will be halved and the current requirement will double, but the voltage will be the same to both headphones.  So, this is fine, up to a point (current requirements and impedance).
 
Going into an amplifier, or two amplifiers, I do not know what the effect would be - maybe different and maybe not recommended?  Or maybe it works the same way?

PM sent. It's a product not made by chord so I thought it courteous not to post the link in the chord thread.

You use it with the Mojo? If so, others might want to know. Nothing disrespectful about sharing that.

Just want to clarify mojo' s battery is on 3V input and whats the input amp on input power when I DIY a ac to dc converter?! 1.5A? 2A? Don't really want burn the PBC board when I do that...

This all sounds like a bad idea...but...

 

[lurk]

It's not small but with the slight cabling it's a great sized stack.



Also there is an option for digital coaxial only so in this mode it produces next to no heat. It also sounds better in that mode.

maxh22, if you havent already do try it out with the digital coaxial mode engaged.

Where can I get tht ultra short coax cable? Custom right?

 

[UNOE]

 

Did you try a different USB cable? Sounds like there is a short.

As for the hum, are you sure the two outlets are on the same circuit? You might have a ground loop. You could also try running the MacBook as a floating source instead.

Yup I've tried 3 USB cables with the same results. I think the two outlets are on the same circuit? I have the same problem no matter where the gear is plugged in within the house. Whats a floating source? Sorry I'm not experienced electronically. 

You can try a cheater plug.  But it sounds like your don't have well grounded wall sockets.  You might need a ground tester for your house.  Or have your landlord test it if you rent.  It may not be safe.
