My first encounters with the Abyss Diana headphone was at an audio-store called F1 Audio. At the time I was more interested in listening to the HEK-SE, so I didn't have enough time to listen to the Abyss headphone, but it clearly left some impression with me. Fast forward 2 months and I'm sitting on a barely padded chair at a meet in Chicago with the Abyss Diana Phi on my head and I'm waiting until my iPhone is left with at least 5% battery in case someone needed to call me or there was an emergency... priorities, right? The Abyss Phi, once again...
