Chord Mojo(1) DAC-amp ☆★►FAQ in 3rd post!◄★☆

[TokenGesture]

Looking forward to DAVE 2 in a year and a half at a quarter of the price

Does anybody know what the actual Artix-7 is in the Mojo.
 
Also any mention of the filter tap length?

 

[Mimouille]

Does the MOJO share the Hugo's signature? As much as I was impressed by the performance, I was not a fan of the Hugo sound in the end.

Mojo it is instead an incredible DAC,the guys at Chord did an amazing job.
Also you have to be careful when playing with the volume as it is very powerful.

It's the new 28nM FPGA chip that allows for the smaller size and half the battery consumption without sacrificing sound quality. I have the filter tap length question sent to Rob and am waiting his reply. I hope he'll pop in this soon enough.

  The Mojo gets incredibly close to the Hugo, in spite of the drastic reduction in size and price - incredibly close.

 
And which one is in front?

 
 
 
1) It's too soon to say.
 
2) I genuinely do not own a Hugo, so I can't directly compare the tiny nuances that may differentiate them.
 
 
 
...but the authority to the sound will be unmistakably familiar to anyone who's heard the Hugo, and I note that I am not alone in hearing this - What Hi-fi appear to really like the authority the Mojo delivers, too.

This has now been answered in one of Rob's Powerpoint slides:

Regarding tap length, I have a sense that Chord are not inclined to declare that at this point in time (I don't know it, either). I totally understand why you are asking about it. One factor in this is that Chord are hoping to penetrate a wider market, with the Mojo, and if they are to succeed in doing that, they need to ensure that their marketing message is to-the-point and not overly-technical - in other words, more about what it does, and how good it sounds, rather than how many ones and zeros are implemented in the FPGA code.   Cynics might point to possible conflicts with Hugo sales as a motivation factor in not disclosing Mojos tap length, and although there might be a degree of outward plausibility to that, I know, having heard it, that the Mojo will sell like hot cakes regardless of tap length. Ultimately, it is sound that matters above tap length, important though the contribution of tap length undoubtedly is to Rob's DAC designs. You're tech-savvy enough to realise that there is much more contributing to the sound of Rob's DACs than just tap length.
 
Having said all that, I suspect that if / when the tap length is finally revealed (who knows when), there may be some pleasant surprises.  Just try to get a demonstration of a Mojo, if you can, and draw your own conclusions.

Thanks - I'll keep this conversation in this thread.
 
It's quite remarkable what kind of processing power we can get in our pockets these days isn't it!
 
All Xilinx Artix-7 chips are 28nm but there are several models

I imagine the Mojo has the low-end one, but you never know

According their briefs MoJo had to wait for new FPGA tech so I am guessing it would be the latest.... Can't know for sure exactly which one it is though.

Mine arrives tomorrow Had a hugo for about 6 months in my main HiFi until it was replaced by a 2Qute. I love the Hugo sound. 
 
I can pretend this is a bit like having a 2Qute at work.

No DAC is perfect for everyone's ears, and that's cool. Such is life.
 
But yes, in direct answer to your question, the Mojo very much shares the Hugos signature, to my ears.

One question, does this support the Apple MFI. So will it work properly with my iPhone 6S Plus?

But you know that you can listen to it during charging. Don't be a slouch!

 
 
And which one is in front?

Ok.
 
Just had a quick listen to the Mojo. Wow! How the hell did they do it for £399? Remember the Hugo is £1400 here in the UK.
 
The mojo sounds just as good. I quickly played them side by side and I couldn’t really tell them apart. I’m going to do more listening when it completes charging.
 
To whoever is thinking about buying the Hugo for portable use. I’ll say you would be mad not to listen to the mojo first. Not sure if Chord have shot themselves in the foot with the mojo. Can’t really see the price of the Hugo staying the same, especially in the used market. These could have sold in bucket loads for £599 let alone £399. Does this mean the Hugo was overpriced in the first place?

You would still need to use a CCK cable with the mojo.

Blown away by the size. Looking forward to having a listen and being similarly blown away by the sound.
