Ok so I’ve had both.
I sold the Abyss and I did love it, but for me the Utopia just suited me better in most aspects.
I prefer the soundstage, I prefer the overall sound and the comfort level is totally different as I’m wearing these 8 hours a day while working and enjoying music so I’m quite blessed I’m home with spreadsheets and music.
The Phi edged it on detail, songs like Natalie Merchant “I may know the Word” had a slightly better crispness to it, but the Utopia for me just raised the levels on all other sections.
I bought the Superconductor cable for it also which did improve it, but they are just a hard fit to wear solid.
I’d struggle to change these Utopias, I have 3 cables now and this new Silver is giving me the detail I missed from the Phi on specific tracks, mainly softly voice orientated music, Katie Melua, Diana Krall etc.
I had Phi’s, Diana V2’s for sale for a while and could have kept them, but I just didn’t see the point, some of you are just headphone crazy
I’m not a hard hitting bass fan, so I’m sure they would have their flaws with silver cable if I were into this.
The cable shielding on this is very nice also, not going to snag and fairly flexible.
