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

[Knee Deep In Epoxy]

In addition to the DCA Noire and Focal Celestee as my possible candidates to pair with the MOJO 2, I note that I can still get a new pair of Focal Elegia, even though they are discontinued. The price of the Elegia from this French source is down to €489 which, on paper, looks like a bargain. I do recall that some reviews mentioned that they were a touch light in the bass, but I guess the MOJO 2 UHD-DSP could improve that.

Has anyone used the Elegia with MOJO/MOJO 2 ?

Not yet but I will when it arrives..

What I would say is I pad-rolled the Elegias with almost all of Dekoni's options. The Dekoni Stellia Pads (not the Dekoni Sheepskins) elevate the bass of the Elegias perfectly without messing up the rest of the tonality. They'll set you back an extra USD 99 but I do think it's worth it.

@Knee Deep In Epoxy ... that's useful to know. Thank-you.

Best is to ignore these Noire fanboys as they have no idea what they are talking about. In the Noire thread, some even were suggesting that my Auralic Taurus MKII amplifier and the Chord Dave cannot drive the Noire headphone.

The Mojo (and thus the Mojo 2 also) is fine with the Noire.

So said Dan Clark himself on audio Science Review site, before he got attacked for it!

I think there's a difference between power and control.
Similar to what Rob Watts points out with the DAC, creating a perfect sine wave is an easy task for a DAC, while it's exceedingly difficult to re-create a highly transient signal.

For an amplifier to generate enough power to produce a certain loudness is the easy task. But to deliver the power and control to make a driver follow all transients as accurately as possible requires more.

Using the much overused car analogies, the top speed in the straight line depends mostly on the available power, going fast on a circuit however requires power, torque, brakes, donwforces and so on to accelerate, slow down and accurately follow the track.

Coming back to Audio - take the Hifiman Arya planar magentic headphone. I had it and used it with the Chord Hugo2. Loudness was not an issue, detail, separation and staging was great. But it was slow and soft, especially in the bass there was no punch in it. On the Arya thread people recommended getting a powerful amp to drive the Arya properly. I never did and instead sold the Arya, but I have little reason to doubt that the right amp would have improved bass impact and control.

There is also the notion of output impedance of an amp which affects its Damping Factor.
The lower the output impedance of an amp, the better it can control the transducer.
A simple demonstration of this effect is as follows:
Get an electrical motor, a small one if you wish. with open circuit on its leads, give it a spin with your fingers, see how easily and for how long it spins.
Then connect the leads together with a piece of wire, short-circuiting it, and repeat!
It doesn't want to spin no more, even if it does, it quickly stops.
The low impedance of the wire acts as a brake!
Speaker diaphragms behave the same way.

I've seen few advertisement shots for Mojo 2 paired with Softears earphones.. I wonder if Chord themselves have a preference for the Softears IEMs. I'm not sure if they are from the same source (the photos), but I've seen them across different websites

In this photos it looks like the Softears RSV

and this one looks like Softears Turrii

Hey there,

i got a question. What USB input should i use, the busy one on the backside of my PC or the front USB Inputs? Maybe there is less electric pollution on the front panel? What you guys use or is it neglectable?

The ones on motherboard.

The ones on motherboard.

So the back panel ones?

So the back panel ones?

I'm using the back panel one as well for both USB c and Micro USB.

If you’re worried about noise (I always am) then an AudioQuest Dragonfly goes a long way to clean things up. A high-value accessory, in my experience.

Do you maybe mean a Jitterbug?

With a jitterbug my iPad doesn’t see the mojo anymore. It doesn’t work.

i had one but disliked it, I much preferred the Radiance in their closed line and Clear OG in open line (and of course utopia but this one I kept it )

Good to know. I was just wondering how as suggested by the OP one DAC (Dragonfly) is supposed to feed another one (Mojo).
