Chord Mojo 2 Thread ___ [product released January 31, 2022 -- starting on page 95 of thread]

Mine has become an essentially permanent fixture on my original Mojo since all my cables are terminated in 4.4mm.

I like the straight exit of the 4.4mm jack versus the right angle of the smaller ddhifi adapter I had been using.

As already pointed out several times in this thread, the adapter does nothing magical... everything is obviously still single ended and it acts the same way as any 3.5mm TRS to 4.4mm TRRRS adapter. But it is nice and sturdy and fits very well to the mojo2 in mechanical aspects and in looks.



In case you are interested; it maps the L+,R+ and GND(L- & R-) of BOTH 3.5mm outputs to the corresponding rings of the 4.4mm TRRRS socket.
I.e. it combines them. The "S" shield/ground is not connected at all (as expected and normal for headphone cables).
Thus it results in TRRRS = L+,GND,R+,GND,( ) in the 4.4mm socket.



An other nice, very well built and a bit expensive adapter from dd Hifi - I do not like the new logo however.

It is a misleading marketing scheme.


You need to understand the difference between single-ended and balanced connections to recognize this.


Using an adapter adds impedance to the signal chain, causing degradation regardless of the adapter's material quality.


A 4.4mm plug with signal poles might work with a shielded cable, but it's meaningless if the cable isn't shielded—like 99% of cables on the market.


Connecting the ground pole of a 4.4mm interface to the ground pole of a 3.5mm (single-ended) connection results in unexpected behavior. The problem is that the shield acts as an antenna, absorbing EMI and RFI, which contaminate the signal's ground plane—a disastrous outcome.

To get the best SQ, microdetail, detail resolution, and depth, just use direct connection 3.5mm cable.

All correct, but what if all your IEMs and Headphones are terminated in 4.4mm plugs for other devices you plug them in to?

Seems like a good solution to me, with the caveats you mention.

I've been posting in the Hugo thread but may as well add here too - looking for any Hugo 1 vs Mojo 2 listening comparisons. Thanks!

 

[Death_Block]

In very few words I've read the Hugo is more sterile and critical and the mogo alot more fun and musical.

 

[headyhead]

Thanks. Have you seen that specifically for original Hugo vs Mojo 2? It would maybe make sense for Hugo 2 vs Mojo 2 (I've enjoyed both; Hugo 2 digs out more detail as you say) - but some folk also say the Hugo 1 is more musical than the Hugo 2.

 

[Death_Block]

It was in reference to the OG Hugo as when I was reading up on them both before buying the mojo they were similar prices

What is fun and musical (or sterile)? To me, the Mojo 2 is slightly warmer and fuller than the K11 but the trade-off is that sound stage and separation is not quite as big or pin point. Both are fun, both are musical ... in a different way, hence I have both.

The ddhifi Mojo 4.4mm adapter doesn’t connect the 4.4mm ground to anything.

They do describe it as a ground pin adapter, I guess what that means in this case is open to interpretation, perhaps there is a bit of marketing going on there.

I think it is over to the consumer to understand what they are buying and ddhifi don’t in any way describe it as creating a balanced output. If people believe it does I think that is on the consumer.

Functionally it is a simple adapter but with a form factor that makes it appealing and I don’t think it is overly expensive for what it is.

In your experience, the Fiio K11 has a bigger stage than Mojo2 even in the max cross-feed setting?

Not sure about K11, but in my experience, crossfeed reduces soundstage on the Mojo 2 considerably - what do others find?

 

[Death_Block]

Don't use crossfeed, for what I've played with so far makes it sound too bloaty and muddy down low

Yeah I don't use it much either. It comes in handy for early stereo recordings where the vocals are mixed in only one channel, and I do occasionally miss it for these recordings when not using the Mojo 2.

I heard Rob Watts saying somewhere that he uses it all the time to reproduce the effect of a live performance, but that's not often the sound I'm seeking with the music I tend to listen to. I do appreciate the option

It does, depending on Xfeed level (I adjust it through Roon rather than Mojo 2's onboard DSP) but I use it all the time for all my headphones. More coherent and involving.

Of course. That's essentially how crossfeed works. It reduces stereo separation by combining parts of each channel with the other, creating a stronger "central" stereo image at the expense of staging. I use crossfeed only in very specific situations (early stereo recordings and some live acoustic recordings).
