I don't have that


This is what I have





And I have this when I click the 3 buttons on top right



You're confusing the instructions for accessing Tidal with the instructions for enabling bit perfect playback.

To get to Tidal, press the orange icon on the bottom right. Then you will see the dropdown menu and "person in circle" icon people are talking about.

Omg. Thank you for your help guys, this sounds sooooo much better than the upsampling crap,, I appreciate you, wow... Time to put some hours in

I uninstalled all other app, Spotify, Hiby, Onkyo. Now i only use UAPP.
Yes, it has some synergy with Mojo.

I'm using 1 headphone out to my main amp, and another directly to my TH-900. Does having the headphone out on the main amp (with it off) take away the power directed to my TH-900?

No not at all, both headphone out are different and independent. So, irrespective of the connection, the power output on both headphone out will be same always :)

Perfect! Thanks for the help :D
 
On a side note, what's the general consensus on pairing the Mojo with the TH-900? I know the TH-900 is a relatively sensitive HP, and some say the Mojo pairs well with it. I have the Mainline as my main amp, should I be using the Mojo or the Mainline to listen to strictly EDM's?

People prefer using the Line out mode when connecting Mojo to amps. In such a circumstance do not attempt to connect a headphone on the other port.

Read 3rd post to see how to activate line out mode on Mojo.

I do use the line out mode with my amp, and don't have my TH-900 plugged in while doing so. I'm not that much of a n00b :wink:

Incorrect. The two outputs are not different and independent, if you mean it has two amplification stages.

3. The output is pure class A at 5v RMS into 300 ohm.

Normally if one amplification section used to drive 2 headphones output, then once we connect the second headphone will make overall sound quality degradation (as the case of Beyerdynamic A20 amp, Grace Design M903, etc). What is the logical explanation of this? As it seems Mojo has 2 separate amplification sections which drive independently for each headphone output."

Of course Mojo does not have two amplification stages. It can drive two headphones with ease because it has exceptional low output impedance, and it has exceptional current linearity. So loading it with more headphones has no effect, unlike other headphone amplifiers.

Indeed, when I initially started designing Hugo I was shocked how poor from a measurement point of view headphone amps were. Poor output impedance, huge levels of distortion, and poor current linearity seem to be typical. And these things matter, if your goal is transparency and musicality.

You misunderstood me, i was saying that both headphone out doesn't share same amplification power. Both are independent while giving output, but both have same amplification stages.

I've been using Mojo with my TH900s for about a week now, and I'm happy with the results. It smoothes out the occasional harshness of the treble, and while Mojo has a bit laid back sound signature, it still sounds exciting with TH900s. IMO Mojo trumps the non-multibit Bifrost + Asgard 2 combination. Mojo doesn't have that animalistic energy and drive of my Bakoon amp, but price and size-wise they are two very different beasts.
