I recently took out my Burson Soloist (1st gen, non-SL) to try with the Atticus. I was previously running the Atticus balanced on my THX 788 alone (cleaner solution for my desk).
I have to say, after listening to this setup for a while, the Atticus feels decidedly tighter, punchier and livelier. Maybe the class A amplification has something to do with it? Or maybe the Burson is just such a nice looking unit, it inspires confidence, haha. Whatever it is, I'm having a good time! I will gladly make space so it can stay on my desk.
Anyone compare Atticus to Focal Radiance or Empyrean ?
I actually auditioned the Radiance yesterday (for an hour, in a quiet room), and the Atticus has been my main headphone for more than 2 months now, so it was my point of reference while doing the audition. Disclaimer: all of the following is "to my ears".
One big takeaway was how much smaller and confined the Radiance sounded compared to the Atticus. It truly sounded like a headphone to me (a closed one, at that). The Atticus has this way of sounding really big: I get lost in its soundscape. During my one hour audition with the Radiance, I was never able to shake off the feeling that I was listening to a headphone that reproduces music. Good detail retrieval, but it's all happening inside the cups and in between the ears, in a manner that sounded kind of artificial to me.
In terms of frequency response / tonality, the Radiance is much "colder" than the Atticus. I know the Radiance is often described as a warm headphone, but being used to the Atticus, it straight up came off as "cold" to me. It sounded a bit nasal in the mids. The Atticus has a really thick midrange (that I love), so maybe I'm just used to that. The Radiance also has that metallic sheen in the upper registers (as with other Focals I've tried before), that the Atticus obviously doesn't have. Because of these qualities, the tonality of this headphone did not gel with me. Bass was good though, no complaints there. Not as bloomy as Atticus, while still being hefty in the mix.
There is one thing I found the Radiance to have over the Atticus: better detail retrieval in the upper registers. Because the Atticus has a thick midrange and a relaxed treble, there are some sounds that are slightly masked sometimes. I'm talking sounds that I can pick out easier even with my HD650. With the Radiance, these sounds were prominent and clear in the mix (clearer than HD650, let alone Atticus). So, if you're craving upper register detail / presence, the Radiance delivers, whereas the Atticus could leave you wanting more.
Overall, I prefer the Atticus to the Radiance by a wide margin. I was expecting a closer race, actually, but that's just good news for my wallet I guess. The set I tried was a demo set from an authorized dealer, that looked as good as new, with a 35% discount on MSRP. I'm almost disappointed I didn't like them more!
