My trio arrived on Monday. I'm going to write quite a bit here because, as others have said, it's quite overlooked. Before it, I had the Z1R for a few days and I wasn't very impressed. This, though, is something else entirely. It's the most cohesive hybrid that I've heard. The mid-range only feels slightly recessed, but it retains some body for vocals and the tonality is correct. Vocals are at the perfect distance for me. I'm just so impressed with this because hybrids and vocals do not often mix well (cough Z1R cough).
I was expecting it to be a bit of a basshead iem because big bass is all I remember from when I auditioned it a year ago, but I my memory was flawed on this account. Bass is very tastefully implemented. Sometimes it is subdued and shy and other times it thumps with vigor. It really depends on quantity and type recorded/produced. The Trio is more sub-bass oriented.
As others have already said about the treble, it does have that sweet quality to it. It feels delicate and smooth. I am not a treble head by any means, but I am enjoying it more than I thought I would. On the other hand, the Trios treble can be a double edged sword. On less than ideal recordings, it can bite a little. It's not fatiguing to me, though. I notice it and move on. This is honestly the only flaw that bothers me personally, but I find it easily forgiveable amid the many strengths that the Trio possesses.
Soundstage:
It's big! I'm coming from an Anole VX, which I thought had a big soundstage. It does, but the Trios is even bigger. I'm not going to get into soundstage shapes and all that. It just feels bigger. Each sound has more room to breath. As a soundstage whore, this greatly pleases me.
Resolution/detail:
It is just the right amount. Listening on something like the VX, you just have detail shoved down your throat. Every breath and pin drop is audible. It's not just detail oriented, it is anal about it. The trio is a bit more relaxed and allows you to enjoy the music more instead of constantly demanding attention.
I'm not trying to disparage the VX. It's been my daily for 6-8 months now and I love it to death. It's just a minor gripe.. or another double edged sword.
I think that covers it! Thanks for coming to my Ted Talk.
