As an owner of the Andro and Hunter (along with the Vega from CA and the Zeus-XR from Empire Ears), I find the Hunter offers something different from the other three TOTL models. Is it better it equal in terms of sound quality and achievement? For me, no, it's not. It's not the disaster some people are suggesting, however - far from it.
The treble is razor sharp on some filters, and the sound is heavily biased towards an analytical rather than musical tone. That being said, the emphasis on the high mids and low treble does make it sound like an absolute detail monster with the right track, the staging is impressive and some music does sound downright impressive with the Hunter. It does need power and a warm source to really hit top gear, too.
Overall, it's a very detailed take on what you would imagine a true "audiophile" tuning would have been described as a few years ago (flat, reference etc). The Campfire gear is tuned for musicality over analysis, despite their very capable technical capacities. That's the overriding impression I get when I put the Andro or Vega in my ears - it just sounds like toe-tapping, enjoyable music. Crystal clear, drift-away-in-the-moment music.
The Andro is no slouch in the clarity and detail areas either, but you have to listen harder to pick up the nuances, as they just pop out of the background rather than being served up on a plate into your brain by the Hunter. For some tracks, this is a major bonus, and on others, less impressive.
I've only had the Zeus around a week, but they probably exemplify what the Hunter could aim for with a bit of a tweak to the tuning. The Zeus are effortlessly detailed without being sharp or harsh, and sound musical and hyper defined at the same time. If Bob can bring a bit more soul and warmth into the background tuning of the Hunter and get a handle on the screaming heat on some filters (not all) then the Hunter could potentially make a jump up from high mid tier to real flagship territory. That's a big if, but it has some unique qualities to the sound that the others don't so if they could be harnessed into a more user friendly overall tone then that would be something really worth shouting about.
Long story short - for the extra money, the Andro and Vega are worth it for me, but the Hunter has impressed me in some facets, and has that certain undefined something that makes me want to listen to it, which is always a good indicator. For their price point, and if you can with the intended analytical tuning, the Hunter certainly compete for me.
For the record, I'm not treble sensitive, but I don't like hot treble things and generally prefer darker and more organic sounding high end.
Hope that long table ramble made sense - will pop some more thorough comparisons in my review when I manage to get it finished!
