1) 64 Audio U12 ADEL - Everything I want in an IEM - Punch bass with great extension, forward mids with fluid vocals. No treble harshness at all. I wish they were slightly more resolving though. Sound signature can be customized using modules.
2) Unique Melody Mason - Some treble peaks but beside from that very neutral and no complaints.
3) Custom Art Harmony 8.2 - Best mids ever in an IEM. Vocals are so resolving and clear. Mid-expert IEM.
4) CA Vega - Best bass in an high end IEM.
5) CA Andromeda - I stand corrected, should have listened to it more before writing a mini impressions post.
6) Earsonics Velvet - Fast punchy bass.
7) Custom Art Ei.XX - Very good sound for its price.
8) JVC HA-FX 850 - IEM with an extremely natural timbre. However, these can't compete at TOTL level. I am still looking for an upgrade to these.
9) JH Rosie - Slightly more sibilant than usual.
10) Sony XBA 3 - Okay.
Time for an Update
1) 64 Audio tia fourte - Perfection. Nothing wrong with this IEM. Nothing. Absolute musicality. It's better than many full sized cans I have heard including the $50K Shangri La which was seriously underwhelming.
2) Empire Ears Zeus XRA - The king of technicalities. No other IEM I have heard does technicalities better than this IEM. However, this wasn't my signature preference, even then I was so impressed by these.
3) 64 Audio A18 Tzar - Very neutral and great imaging. I liked it but still not my preferred sound signature.
4) 64 Audio A12 - After hearing the fourte, this IEM is lacking in many areas.
5) CA Vega - Best bass in an high end IEM.
6) Unique Melody Mason - Some treble peaks but beside from that very neutral and no complaints.
7) Lime Ears Aether - Good IEM with fantastic Treble and vertical soundstage and separation.
8) Custom Art Harmony 8.2 - Great mids ever in an IEM. Vocals are so resolving and clear. Mid-expert IEM.
9) CA Andro - Lacks sub-bass but great Treble.
10) Dita Truth Answer Edition - Not bad at all though my time with it was very limited.
11) Earsonics Velvet - Fast punchy bass.
12) JVC HA-FX 850 - IEM with great timbre. However, these can't compete at TOTL level. I am still looking for an upgrade to these.
13) JH Rosie - Slightly more sibilant than usual.
14) Sony XBA 3 - Okay.
