I have Utopias, TH900mk2, LCD-2, HD800, RS1e all going through a Hugo 2 (soon to be Hugo TT2 with M-Scaler). For me, the Utopias (with Lazuli Reference) through a Hugo 2 with the Warm filter on, is breathtaking for metal (The guitars on both With The Dead albums sound so crunchy and good).
While I'm happy with my current lineup of headphones, I'm always looking for something better. Given what I have, how would you all compare the Abyss 1266 Phi TC or Meze Empyeran for metal listening?
That's a droolworthy collection for sure! Where a relative newbie like me pauses, and bearing in mind I haven't auditioned all of the gear you mention, is that apart from the Fostex it sounds almost like a progger's dream. I don't mean in the sense of slightly risible 4 o'clock concerts and fringe hairstyles; rather as in lean, precise, technical. Apart from grindcore I'm into the same genres you mentioned, and pretty much in that order too. I am forced to use closed-back hps or iems in my small Parisian apartment, but actually enjoy them a lot for studio-recorded metal. I'm not big on Focal or Sennheiser - both are big in France, so chalk that up to the same contrary spirit that makes me enjoy Forgotten Tomb I guess?
Having heard the Utopia and Audeze, I would rate the Empyrean as a sidegrade. Precision is their selling point for me, but you don't lack that obviously in your collection.
The Abyss give the best soudstage I have ever heard; where the best open-back sound like you've strapped loudspeakers to your ears, the Abyss feel like a proper concert venue has been grafted to your head. They are beyond holographic - you 're just there, like your ears and brain have travelled through space/time and you're
in attendance - well you got my point. Amazing for jazz and classical. Not a game-changer for studio recordings.
I have never heard ZMF gear but from following this thread I fear the day I will - my hi-fi purchases tend to top out around $600 but a part of me in the market for something more expensive, closer to TOTL. I just haven't heard anything that justifies spending crazy money to upgrade from my Final Audio Pandora Hope VI or IMR R1 iems. So the Eikon and Atticus both beckon and threaten... Well actually I have one upgrade path in mind, which is the Hifiman Susvara. That's ten times the cost of already great headphones, and from what you wrote not quite the price range you're looking into. I'd still urge to audition them in case you never have, the sense of control, of effortless power is well-suited to metal.
Other than that there is the Sonorous line from Final. The distinguishing feature of my VI is their vectoriality, they present music as a flow, rushing through, racing forward - I don't need to explain why that can be great for metal. It does soundstage well too, so it's a sort of best-of-both-worlds combination. The even better Sonorous VIII or X could really please you and depart from your current tunings.
PS: you weren't kidding about that crunch on With the Dead
