Looking beyond the frequency response, the Atrium’s channel matching (like both the Vérité’s and the Utopia’s) is excellent. In terms of distortion, my measurements show that that the overall level is roughly the same between the Vérité and the Atrium, with both having slightly less distortion than the Utopia when tested at my approximately 85 dB frequency sweep level. The big difference, though, is that the Atrium’s distortion leans much more towards the second harmonic. Whereas third-order harmonics compete with the second-order ones, particularly in the bass, on both the Vérité and Utopia, the second harmonic dominates across-the-board (including the bass) on the Atrium. While I don’t want to read too much into such low-level differences, that might help explain why the Atrium’s bass sounds so smooth and clean.

. I like having both when my house is noisy and I want to listen, I listen to the STEALTH, but as I am writing and the house is quiet the EXPANSE has made the music alive and more tuneful. If your looking for tonality and musicality either headphone will deliver.

Musicality is the most important aspect of any performance and the EXPANSE has a sound rarely if ever heard from any planar design. No matter what played the EXPANSE made the experience memorable. I found myself listening into the wee hours of the morning. Everything else became secondary and the EXPANSE allowed me to relax and get into the music. The soulful EXPANSE is a creative marvel with its ability to disappear. Comfortable to wear for marathon listening sessions it delivers everything you could want in reference transducers. Together with my reference Lina system, it’s headphone listening at its best. Once again Dan Clark sets a new benchmark in design. Highly recommended and a strong contender for product of the year.

With its 2m cable and neat folding action for easy storage, it would appear that the Aeon 2 Closed is best suited to listening to music on the move and its comfortable earpads and lightweight design will certainly make your journey a congenial one. For those that like their lower frequencies, the impressive bass extension is a real boon although the treble could do with being a touch more extended. Having said that, the soundstage is spacious and insightful, meaning that at the price this deserves to be on your audition list.
