Well, you like what you like. Part of the hobby is figuring out what that may be. What you like may change over time too. Since you're bumping bass and treble, you obviously want that.
It's not that the DBA-02 lacks bass. It's just that the frequency response does roll off on the low end and that the notes have very fast decay. In a way the DBA-02 has "more" bass than the RE-Zero as it is more aggressive than the RE-Zero, and this can be enough to say "well, I hear things down low." The RE-Zero has more decay and a fuller note though which fills out the presence of those lower notes better than the DBA-02, although I still see the RE-Zero as a relatively lean, clean earphone. I just see the DBA-02 as more so and this can pose problems when trying to reproduce low frequencies. A simple example is taking a recording of a cello. Listen to some low notes where there's moderate string vibration, body vibration, etc., things that require reasonable decay and texture to present. The DBA-02 will fall short, significantly enough to not even perceptively show some of the details. The RE-Zero is more filled out and brings forth more information. You will hear more things from the RE-Zero than from the DBA-02 despite the DBA-02 being faster and arguably more detailed. It's just that the DBA-02 is good about the highs but not so good about the lows. It's not just about hearing stuff down low. It's also about creating a meaningful sound and the DBA-02 isn't very good about that.
The Triple.Fi 10 is a highly detailed earphone. It is also quite thick in note for a BA based product. It isn't the most revealing BA based product due to the thickness of note. However, the overall sound quality is very high. It's very refined as well as very fun to listen to. The common complaints with the earphone revolve around the recessed mids, but since you're already boosting treble and bass to get a sound you want, the Triple.Fi 10 starts more like that already meaning it's closer to what you're looking for. Fitment, build quality, and the cable have always been issue with the product though, but the concern depends on who you ask. For me, I've had little problems in any regard. I've owned a pair twice, each for roughly half a year. Fitment is fine as long as you find a tip that fits your ear well. Historically the tip selection of the Triple.Fi 10 where just small/medium/large single flange tips which isn't exactly much to work with. Later they added Comply foams which helped out a lot. However, it can be nice to invest in a few more tip options to make the fitment process much simpler. Monster has a big variety pack of tips that include silicon and foams that offer some variety. A number of manufacturers sell their tips separately so you can get a variety of bi-flange tips to work with. I've liked the MEElectronics ones personally like found in their M9. They seem to fit my ears well. It's all about finding tips that work well with your ears. It's easy to blame the earphone, but the tip is always the issue. The cord, I don't know. It's not the greatest out there. It's obviously not as robust and durable as some offerings from Sennhieser, Shure, or Audio Technica. However, it's not terrible either, and at least for me it's worked plenty fine. The old version had a stiffer cord that had some memory issues. The newer version is softer, feels flimsier but is nicer to work with. It's easier to wrap up and doesn't have memory. My only suggestions are don't pull out the cord from the earphone unless you have a good reason and don't be stupid with the jack when removing. You have to be pretty gentle disconnecting the cord from the earphone, slow and easy. The newer jack is now straight and a lot less robust than the old 90 degree one. Being rough with it, yanking on the cord, etc. will likely cause eventual issues. Just be nice to your equipment, and you'll never have problems.
