3Max is burning in and I'm hearing some slight changes, mostly in the midrange and treble. Out of the box, the treble sounded a bit more emphasised with a lighter note-weight, making the presentation sound somewhat U-shaped because sub-bass also sounded elevated. However it's now sounding more balanced, with mids coming forward in the mix and in-line with the treble. However, sub bass still sounds slightly more elevated than mids and treble.
Staging/imaging is fantastic on 3Max, especially stage depth and height. To me, 3Max has a rather forward presentation, so the centre image gets pushed very deep and creates an excellent sense of holography. With the Oriolus Traillii, this is one of the most holographic IEM setups I've heard. A must-hear if you own a Traillii imo.
For IEM pair ups, so far I have tested Traillii, EE Odin, Elysian Annihilator, 64 Audio Fourte Noir, U12t, VE Elysium & Sennheiser IE900. All of them pair up exceptionally well, except for Elysium and U12t, at least for my preferences. I found that both Ely & U12t's treble and upper mids sound a little too heavy and thick. I personally prefer both those IEM's with Cayin N6ii R01. The three standouts for me with 3Max are Annhiliator, Odin & Traillii so far.
Compared to other DAPs I've got, I still think 3Max sounds most similar to SP2000 but with a more expansive stage, better layering and an improved balance between bass mids and treble. SP2K has a more mid-forward presentation with treble and bass sitting further back in the mix. Shanling M8 sounds warmer, bassier and not as technically proficient. N6ii R01 sounds airier, with a lighter note-weight and a smaller stage.
Compared to Sony DMP-Z1, I hear Max being more lively, energetic and more forward overall in its presentation. Conversly DMP sounds more laidback, organic and natural, but comes off somewhat less exciting. DMP's stage sounds a bit wider, but I think 3Max sounds deeper. Height is quite similar. They both have completely black background noise, except for a bit of EFI on 3Max which hopefully will be resolved soon via FW update.
