I've been thinking about stepping up my IEM game and I'm having a tough time deciding which IEM to get. A little history, I have a Tin T2 and Final E2000. I had a Tin T4, but sold it because I found it too fatiguing and the treble made it feel a bit messy to me. I like the tonality of my T2, but wish it had a bit better bass extension and find it to be just a bit sibilant at times. My E2000 is nice, but has too much midbass. Given this, I actually think the Final B3 looks like a good all-arounder, but it much more expensive than the other two I mentioned. With the Massdrop Plus only being $200, I am considering it, but have heard about build quality issues. I haven't heard any complaints about the FH5, however, my ear canals are a bit small (T2 isn't always very comfortable for me), so the FH5 may have some issues with the fit.
What do you guys think would be my best option for upgrading?
