The Mojo 1 is too digital and harsh which is not correct soundwise.
So one of the portable benchmarks I have used, it is not amazing. The Chord Dave absolutely destroys it. But that is to be expected as it is a consumer device which simply has a headphone output as an after thought.
I can take my AFC 2 Noire for example or whatever headphone and listen on this "consumer level" portable device and it is actually quite enjoyable to listen to. With the Mojo, there is always some "harshness" and "digital" sound which ruins the listening experience for me. The Mojo 1 is probably better at "technicalities", but the listening experience is not that great for me. Now I won't mention which device it is as head-fi will probably explode.
The Chord Dave (fully optimised to eliminate all external noise) also doesn't have this problem of the Mojo 1. I can take my Focal Utopia (with super high-end cables) and it sounds super smooth, relaxed and analog with a massive soundstage. Yet at the same time, you hear absolutely everything. Basically everything sounds amazing on this setup.
So I basically miss the sit back and enjoy all the music experience with Mojo 1. Now I know I am the minority, so you should probably ignore my opinion about the Mojo 1 as the consensus is that the Mojo 1 is somehow super amazing.
I guess I must have a particular set of ears that somehow finds the Mojo 1 "digital" and "harsh". I honestly thought my Mojo 1 was broken all this time.
