I bought the Mojo the day they arrived at Stereo Exchange in NYC. The FPGA technology, Hugo, and Chord's other products made me confident in taking the risk to do so without even a demo.
I likely would not have appreciated its capability and value for the USD 600. Its ability kinda creeps up on you over time; so I listen to my reference tune everyday to compare experiences longitudinally as an experiment control. Steely Dan's "I Got the News."
Here goes, with my description, admittedly we are discussing subjective, personal views and vocabulary nuances.
1. "Detail" versus hearing more.
To me, detail, is often inferred as harshness, strict boundaries, or "bright", digititus, sibilant. Whereas, I experience more entire instruments, and the timbre and attack of acoustical ones which come out more in live studio or broadcast recordings. Apologies if I am not clear.
2. Photography metaphors for musical.
We speak of the golden hour when the sun is lower and light passive through more air, in contrast to summer sun when it is overhead. The former is not out-of-focus, rather it is more saturated in color, the visual frequency. This is how I describe the Mojo sound signature. It is pleasing and does not make you work when you want to focus on the music. I even enjoy listening to songs I have to date not particularly liked.
3. Chord, the Apple of head-fi Audio?
I think of how Apple designs the hardware (they used to make their own CPU chips IIRC) and the software to ensure it works in harmony as a whole; in contrast to the WinTel industry. It is that control over their DAC/AMP (I call I their "DAMP", as a wet or analog sound) that I bought into with the Mojo.
4. Amp
Glad to see their analog output is so clean as it can be enjoyed as a line-out sans the double-smiling effects. You get to enjoy its resolving ability and your own choice of amp signature.
