Well, so after I've received the recommendation for the Dan Clak Aeon RT, I would like to give my first impressions. Comparing against the 2019 Hifiman Sundara, Beyerdynamic MMX300 and the Philip Fidelio X2HR I feel like it truly is the perfect combination of the strengths of the before mentioned. The MMX300 in my opinion is very well balanced all around, but detail, clairty and especially tremble is not on par with the Aeon RT. Soundstage and overall Detail might just be a little behind the Sundara, but not by much - actually it is hard to compare, because I was missing the bass and sub bass sections so much on the Sundara, that I cannot judge transparency of layers, because it would be unfair, obviously the Sundara delivered almos two whole less layers. Having that said, I'm happy with separation and transparcency. Listening to "Try Sleeping with a Broken Heart - Live at Metropolis" by Alicia Keys it is quite amazing how the pumping bass doesn't disturb any of the cymbals or layers of lead/background singing. Responsiveness and Accuracy are just amazing. Main Difference to the X2HR on first glance, besides overall quality of detail, feels like that the Aeon RT does punch when the source requires it, but not all the time, like the Fidelio. Listening to some Live-Recordings of Esbjörn Svensson Trio I can really appreciate every singe note that Dan picks on the bass, all the dynamics are there. I'm 32 now, but what would I give, just to sit there one more time in 2008, listinging to E.S.T. live... man, it's just a headphone, but it totally brings back and revives that moment.
Interestingly I prefer the stock settings over Amir's EQ profile for the first time ever with the Aeon RT.
Man this is amazing... I'm hearing whole new things, like for real. I'm even spotting little mistakes in Live-Recordings now. When listening to guitars, for the first time actually and that might sound weird, but I can feel, not just imagine, how it feels for the guitar player to touch the fretboard... quite amazing, it's so much information, so immersive and it just doesn't get muddy. I'm listening to "Building the Churk" by Steve Vai and find it absolutely stunning, how the guitar just swims in the middle of the mix, instead of covering the carpet of rythm instruments up top.
Only thing that I really don't like for now, is how "well" sound is being transferred through the headphone, when something touches it from the outside, like clothing or wires. Interestingly also, for closed backs, they don't block a great amount of ouside noise, which I don't really mind for now, just a bit supprising thb.
After all, I cannot thank you guys enough for that recommendation.
