Do we foresee a Chord Mojo 2 coming out soon?
So probably no Mojo 2 coming out, so it's relevant if you want it for what it is: a very small mobile DAC/amp that might be somewhat sensitive to EMI if it's near your phone. Many have tried to use it as a desktop DAC and that's caused battery failure issues for them, so it really depends on your use-case:
(1.) If you're looking for primarily a desktop DAC/amp, it's not the right fit for the $$ IMO. First, it's not going to have the power of a desktop system, and second, you can get an excellent Mimby/Magni3 stack for $350 or add a few hundred and get the Woo Audio WA7 DAC/amp if you want beautiful ... and third there are many other choices like Audio-GD, massdrop specials, etc ... or you can go even cheaper with a Topping D30/A30 stack or SMSL. In short, you're paying for size in the Mojo and not using it in a desktop setting and you can get equal or better (or much better) for equal or less, and if you're looking for design for a few hundred more you can get that too.
(2.) If you're looking for portable / transportable, it should be on the short list. It's a good or great DAC, can drive most headphones, and it's small ... but it can be sensitive to electro-magnetic interference, i.e., your cell phone might cause a slight to loud buzz, so it's probably not the thing to rubber-band to your phone. However if you need more transportable, i.e., you set it up at your desk at work, listen all day, hide it in a drawer for lunch, then take it home and listen more there, it's great for that. But there are competitors like the iFi micro DSD black label (if you wait you can find them for ~$400), the new micro version of that, and some others (e.g., geek out, Fiiio, etc). For me it would come down to the Mojo and Ifis.
Personally I just got one as the first thing to start building my headphone system - I auditioned lots of things, but the combination of its form factor, great sound, and coolness (if you like the design) is great for me. But I also got 2 sets of HPs (hd600s, th-x00) and the Jotunheim, following the spending priorities: headphones > amp > dac > cables / ICs / balanced. In short, you can buy, say, new Senn HD650s and a Mimby/M3 stack for the same price as just the new Mojo, so you have to decide what your priority is and if you're cash strapped or looking for the most for a limited dollar it looks less attractive. If, OTOH, you have a decent budget, need a portable/transportable option and like the design then it's great.
