Great feel, incredible sound even before full break in. Very nice sound stage with clean separation of vocals and instruments
Note after 2 days of break in. dialing in filters ( none ) and the CEntrance DACport HD, ( High Gain) and figuring out what level volume need to get headphone to open up. Note I found many amp would just plateau. Now DACport HD is not perfect some EDM ( Moby, etc ) song will clip on DAC/AMP at volume.
I wondered into an old album from the Squirrel Nut Zippers, "Hot". ( 1996). The third song "Memphis Exorcism" with beautiful Trumpet solos, kick and snare holding time with a upright bass thumping away, then guitar sliding in, AEON has sold solid separation with engaging detail and staging. Then the 7th song "Hell" rolls in with another the trumpet solo just draw you in, with Vocal and background singers make you feel like you down at Elephant room in Austin.
Next big surprise was Taj Mahal's "Dust My Broom". the Harmonica feels like you blowing it , drums are holding time to the left and guitar is next to you.
Walter "Wolfman" Washington "Save Your Love for Me" his deep vocal just layer forward over brooding jazz cords
Tom Petty "Free Fallen". wow another great song on the Aeon. Love vocal, guitar, drums and separation, as back ground vocal slip in.
This one staying in the collection, but I would recommend good DAC and higher power Headphone Amplifier. Example where you could use little more juice, U2's "Cedars of Lebanon" opening organ clips the CEntrance DACportHD.
Update it works fantastic with the Xduoo XD05 Plus DAC/AMP, it really opens up the headset.
Would recommend to a friend.
