i'm very happy with my Ifi idsd diablo
Very nice!
First of all I do not manage to adress exactly the correct area of the frequency band, so while I manage to improve one area another might suffer.
Some great suggestions from others. The first thing I would do though is to go
HERE where you can find out both your trouble spot in your hearing, and/or where the trouble spot is in the head gear. Then you will know exactly where to subtract using EQ, and how wide you may need to make the Q or BW, and by how much.
Also, if you are using android or Windows, or IOS, or MAC I would suggest to you an app called
Neutron Music Player. One (of the MANY) thing that is great about it is the EQ/PEQ. You can actually mix and match (i.e. you can make 40Hz a low shelf PEQ, and make 80Hz a peak EQ, and etc...). It has some of the best DSP out there (without having to mortgage the house to afford it, like some other top-notch apps will).
Anyhow just my $.02, and as always, YMMV!
Secondly, some of the drivers are simply more competent than others.
Sadly, EQ will NOT help here, and there is really nothing that can be done short of trashing the poor drivers.
So does anybody have recommendations for earbuds with great mids, technicalities and relaxed upper mids and lower treble for me?
I am not asking for great extension on the upper and lower end! (Some extension would be nice to have)
It really depends on your budget, what you consider great mids (i.e. do you like thick, thin, recessed, forward, lush, wide, intimate, etc...), and what type of shells you desire to have.
Having said that, for me the the
Moondrop Chaconne still comes to mind. They have some of the best technicalities, mids and treble, and are not boosted in the presence region (upper mids, lower treble).
Have a look at
these reviews; especially the one from our own
@RikudouGoku. Ironically, most of the time, our likes/dislikes are pretty opposite, but this review on the Chaconne is pretty spot-on from my (subjective) perspective.
[sidenote]: There IS another set that we both agreed upon as well, once upon a time. It was the Audiosense T800 (8 all BA IEM)..

That was nigh on 5 years ago (come May).
Hmmm.... Technicalities for me are Dynamics/Transients, Resolution (not only in upper mids/treble!, low distortion)
Imaging and staging are a result of tonality/frequency response and technicalities combined. I think brighter tonality --> better imaging,wider stage.
darker tonality with deep bass less wide, but deeper stage.
Everybody looks for something different... i do not care about width a lot, but i want at least some depth and 3d feeling to the sound. The more natural the frequency response sounds to me the more natural the staging will be for me. That is how it is for me. You just might be into brighter sound signatures?
You are correct here. But... technicalities also encompass staging, imaging, layering, separation, detail retrieval, etc... Basically anything that is not a derivative of actual tuning. Because you can have a set that has a large dip in the upper mids/lower treble, but they can still have a wide sound-stage, for instance. Some of these are not isolated from one another and if poor, can cause other parts to suffer as well.

Point is that you can have any kind of tuning you like and still have fantastic technicalities with the right setup.
The thing is (and ChiFi does this a tremendous amount) that boosting the upper mids (again, for instance) can enhance the soundstage that is already there (or not there to begin with

. This is a trick done in tuning. The goal then becomes to find a set that has all of those technicalities that are really good, but with no "tuning tricks" being used to get there. This is rarer than you might think, and even some of the big-name companies use this (rather than have an outstanding driver, shells, tuning, etc...)
A perfect example I might think of is
@FranQL. His tuning is straight forward, and never has anything offensive in the tuning just to accomplish some goal of technicalities. But, with all the buds I have from him, the technicalities are fantastic as well. And that stems from the fact that he chooses the right (quality) driver to pair with the right shell, and tuning materials as well. His buds are (very well) known to have great tuning, but don't suffer poor technicalities as a compromise.
This is very interesting! Just a few pages back, someone else said they used the RW-2000 as their daily driver, was it @baskingshark? Because of my disappointment with the yincrow calf i had initially decided to not get any other yincrow buds. But especially the RW-2000 gets a lot of praise and seems to be one of the more universally liked higher end buds along with the yinman600...
The RW3000 seems to be a bit divisive, some like it a lot, some don't, and I have not heard a lot of talk about the RW1000. Where are the differences in between the 3? I think I have read that there is some slight boosted upper mids to the RW3000, which would probably be not good for me (seeing I do not like the "hardness" in the yincrow calf lower treble). Especially, where are the differences in between the 3 yincrow offerings regarding the upper mids/lower treble region?
There is a bit more than a slight boost on the RW3000. The RW2000 have a slight boost on the other hand. It is probably one of the reasons I favor the RW2000 just a bit over the RW3000 (still fantastic as well though), because (as you probably already know) I am very sensitive to that boost (but not mid to upper treble).
The RW2000, while having a slight boost in the upper mids, also have a tad bit of a roll-off in the mid to upper treble, which makes them come across as somewhat smoother or less aggressive. The RW3000, on the other hand, have a bit more boost (that the RW2K) in the upper mids, but are also somewhat aggressive in all the treble regions as well. This can make the entire tone sound much more aggressive and "bitey". To my ears, the RW3000 is more analytical, but on the aggressive side; as opposed to being analytical but smooth (like the Chaconne, or HD800S, etc...). The RW2000 are smoother, so they sound more musical, and without being too aggressive.
As mentioned, both sets are fantastic, and you might like either, but this is how I hear them, compared to each other. As for the RW1000, I never got those, so can't comment on them. There is a fourth option in the RW line though, and that is the
RW1000 Bass Pro.

Though I haven't heard those either.
