Hi

Thanks for the answers guys. Anyone know where the 3.5mm to 3.5mm digital cable can be purchased in the UK or Europe?

Regards

Darren

Select your connections in the drop down options. You want the X3ii/X5ii to Mojo option. :wink_face:

Its thousands .....Santa has put several extra big Sacks on his slay he's even having to add more reindeer to help pull it and we are sending some extra shipments up to the North Pole just in case he needs even more.

Well, I can see the 'Chord', but not the Mojo!

Perhaps the Mojo's are all wrapped up in suspenders and they can only be revealed at their destination.

So I got a Mojo myself last Saturday. Due to busy pre-holiday season (and the ever-tempting Master- sucking up most of my music listening time) I didn't use it much so far, but what I heard makes me look forward to taking it with me on vacation. Easy connectivity with my iPhone, separate charging port and dual-out are very welcome features, it's small size is astounding. Never liked the Hugo due to its physical appearance and design concepts (including user interface design), but this one corrects most of its brothers issues.

Had the good fortune of running into the mojo and hugo today at a little audio shop in Taipei today and did some listening with my UERM.

Both devices delivers some really nice punchy and engaging sound. I feel that theyre a bit more forward sounding than my personal preference but i cant deny that they really sounded good!

The mojos got a lot more heft to it than i expected and its also a lot smaller than i expected despite seeing so many pictures of it with the original AK100.

The hugo to me is still a tad better, but you definitely hear the hugo in the mojo. At about a quarter of the price of hugo though... The mojo really is an absolute beast and can compare to some very good high end daps and portable devices!

Fair play to you bro! coming on here with your views, would you mind explaining a bit more what you mean about forward sounding and what are your current favorite DAP's.
 
Forward to me would mean an in your face presentation that I do not like either.
 
I see you have tested lots of DAP's - only when you get a chance to reply.
 
I have a Hidizs AP100 DAP but have heard from others that the digital out does not improve the sound by much with the Mojo and hence my hesitation to get a Mojo.

Hi
 
What's the best online shop to deal with in the UK for the Mojo. I live in Jersey, Channel Islands, so will need a retailer that can take the dreaded VAT off. Custome-cable.Co.Uk can, but I have never dealt with them before.
 
Regards

I will contact him. I need a cable to connect Fiio X7 to Mojo but I would prefer the plugs be right-angled.

I understand those concerns to - after all the data is the same. But there are solid scientific reasons why they can make a difference.



 


In the 1980's, people started talking about mains cables making a difference to the sound quality - and I didn't believe it either - particularly as my pre-amp had 300 dB of PSU rejection in the power supply. But I did a listening test, and yes I could hear a difference. Frankly I still could not believe the evidence of my own ears, so did a blind listening test with my girl friend. She reported exactly the same observation - mains cables did make a difference to SQ.


 


To cut a long story short, I proved the problem was down to RF noise. RF noise inter-modulates with the wanted audio signal within the analogue electronics, and if the RF noise is random, then the distortion is random too and you get a increase in noise floor with signal. This increase in noise floor is noise floor modulation, and the brain is very sensitive to it; you can perceive tiny amounts of noise floor modulation as a brightening or hardening of the sound. By tiny I mean the noise floor modulation needs to be well below -200 dB, so the brain is very sensitive to it. With the right test equipment, you (APX5555 is only test equipment that has no innate noise floor modulation) can easily measure the effect.


 



The RF characteristics of the cable can change the RF noise that gets injected into Mojo's ground plane, and this is the mechanism for changes in smoothness. You may say why can't you make it insensitive to it; well I go to silly lengths to RF filter and decouple, and use dual solid ground planes on the PCB, but you can't remove the problem. For Dave, Hugo TT and 2 Qute I have galvanic isolation, and this eliminates the problem (along with other SQ problems such as sound-stage depth). But I can't do this with portable devices, as it draws power from the 'phone. That said it's less of an issue with portable electronics as they are less power hungry and create less noise.



 



So what are the best USB cables? Firstly, be careful. A lot of audiophile USB cables actually increase RF noise and make it sound brighter, and superficially impressive - but this is just distortion brightening things up. Go for USB cables that have ferrites in the cable is a good idea - it may also solve any RF issues from the mobile that you may have too.

It is fascinating to read what I heard but was unable to explain scientifically be explained in detail as you have done here. I've gone through all my old cables and removed all the snap-on ferrite devices and now I've got the permanent one that's attached to my usb as well as 2 more. It's weird how it makes the bass sound more prominent but I love it. Will eventually upgrade to one of those fancy ferrite shielded usb cables.

Guys I have successfully removed all RF interference. It's literally the same as airplane mode now. I'm using a cheap usb cable with a permanently affixed ferrite device that goes into the mojo. On the other end PAST the apple CCK and right up against the phone(it can't go any further) I have a large removable circular ferrite device. It's probably an inch across. It raises the tail end of my phone off the ground probably a 3/8 of an inch. I tried texting, browsing, streaming-all dead silent.
