It seems we tend to prefer different sound signatures you and I. Interesting to read why you like a more neutral or "correct" sound. Everything makes sense. Not being ultimately driven by a "perfectt" sound reproduction, I have no problem with giving up some details (you know, these 5% you can get with a "better" IEM set) in favour of more "musicality". I have been listening to warmish, romantic, darkish sounding devices (turntable and CD-Players) for my whole life. It started in the late 80's with my father's setup. In the desktop and portable game since 2013, I struggled finding combinations that I really liked, often being disappointed with the "digital" sound I got. I will pass on the material that I bought and sell to reach. I spent 5 figures amount in the previous years and now being more than happy with 2 Daps, 2 amps, 2 full-sized headphones and 5 pairs of IEMs, all of it being quite affordable, but showing great synergy for my tastes. My turntable and CD-players are still getting a lot of love from me, though.
So, sorry for being so talkative
, back to your question: At the moment, I really like the Blon BL-03 and the Final E5000 with the Calyx M. My other IEMs also are great with it, but I prefer these 2 single DD being fed by the Calyx M. I get completely lost in the music. Such a nice feeling. The Fibae Black is also very nice, especially in the midrange and with vocals.
I am not really interested in spending to much at the moment in order to get real expensive TOTL IEMs. In any case, the next steps for me is to take the CIEM road. I am saving for this, no new purchase for a while now. Then, I will have to choose wisely. I am looking for Fibae 7, itsfit Fusion (or their coming flagship) or maybe EE LX. Who knows what 2020 will bring. I am also open to suggestion if you have some.
