Reading all these comments about expensive cables improving sound of the mojo, you guys needs to realised its expectation bias.
When I hear "this cable improved the sound of my Mojo" just know this, if you really believe it will or expect it to, then your mind will simply send of the necessary signals to make it happen.
Concentrating and focusing on a high quality instrument with no distortion in a track can give the impression of clarity.
Many times I've picked up the Mojo, some times I think to myself, hang on, the sound quality isn't like it was before? To find the next time I pick it up my faith in the Mojo is restored. No cable change. Am I playing the same song over and over each time I pick up the Mojo? No. I play different material, recorded by different people, in different rooms, and mastered in different ways. Playing various material each time you pick up the Mojo can give a false impression.
Chord bundled a basic looking usb cable that sends 100% of the data to the Mojo, no fancy branding or a
esthetic involved. If they thought that a Usb cable would of made the sound better, perhaps they would of offered it as an extra ?
If you feel that your Mojo isn't doing what you thought it should do, maybe your expectation was slightly too high to begin with, or your headphones are the limiting factor - they are at the end of the audio chain.
