I have finally received my Mojo from the dealer last Friday and have played with it for a couple of days. First of all a couple of observations (and questions):
1. The construction is solid and impeccable but I did find the volume spheres a bit tight - in fact once I had the "+" sphere stuck in the pressed position and the volume kept going up and I couldn't get them unstuck before the music got too loud and I have to pull the plug on the earphones. Will these balls loosen up in time and I don't recall the demo unit at the dealer having this issue. Now I have learned to press them straight down instead of "into" the unit to avoid having the same issue again. Hope the issue will take care of itself over time or I have adapted to it.
2. When the unit is charging it emits a physical hum - not loud and you certainly can't hear it without pressing your ear very near the unit, but I do realize some very early units were suffering from a component defect. I am wondering if my unit is in the affected batch. Perhaps someone from Chord can supply a range of serial numbers for us to verify? Is a very minor hum during charging normal?
3. When I listen to the Mojo with my Shure SE846 and wow. I have never heard them sound so good. I listen to mostly vocals and use the black filter on the SE846 for more warmth.
4. My T5p on the Mojo also sounds good, but just a tad too neutral for my tastes, as the T5p are also very neutral phones and it could use more body in the bottom end for better synergy. I guess I need to pair the Mojo with more colorful amps/phones in order to better enjoy them. While the Mojo is technically better than most other DACs in the price range, I find for example the Meridian Explorer sounds more enjoyable with the T5p due to its warmer signature. But the Mojo is a keeper because of its other traits.
