(a few posts above)..... UE900 IS pretty neutral. An ever so slight sub-bass boost certainly does not screw up the sound (still laughing...) but only makes it sound neutraly realistic!
I think you misunderstood me slightly. I don't think that dual drivers are necessarily an improvement "over anything that ety offers". In fact I think the ety er4s is an improvement over most multi-drivers I've heard. However, a multi driver isn't necessarily worse either. It comes down to how the drivers are used. One driver can (and I believe in this case "does") sound better than multiple drivers. While technically I'm sure multiple drivers CAN sound better than one, thus far I haven't heard that situation. The situation I have heard is that multiple drivers DO sound better when they are used to COLOR the sound, not when neutrality is desired. In other words, when coloration is desired (i don't desire it) they handle the coloration better and thus sound better "colored". I don't mean that the "sound better than the non-colored", but simply they allow the coloration to work well without ruining other areas because of it.
Regarding the UE900. No matter what perception you have of it, it is not neutral. I believe you can have a non-neutral earphone that sounds "natural". That does not mean it is neutral. Look at this graph of the UE900:
Even on their graph page they SHOW you what is needed to make it neutral down in the accudio graph. Lower everything from 50hz to 1khz, raise 2khz to 7khz and lower 8hz to 10khz. All rough figures there, but you get the point. That is about as V-shaped as they get. In fact, it is very similar to the 4R, which I see you have based on your profile. I don't mean it sounds the same, but that it has boosted low and high areas creating a v-shape. The boosted areas differ though.
While there are things that can make these sets "seem" flat or at least "natural", they are not neutral in the studio monitor sense of the word. Use a parametric EQ and flatten and raise the sections indicated on that graph page. You WILL be closer to neutral. If you don't like it, you don't like neutrality in the frequency response. This doesn't mean that you don't like neutral if you don't like the ety. Don't take it the wrong way. The ety isn't perfectly neutral either. But it is a lot closer than the ue900.
There's nothing wrong with that. You might prefer a V-shape to a neutral curve for an earphone, because you find it sounds more like a speaker. That doesn't mean someone else does. I don't want to hear any arguments against the graphs either. :-P No matter what graph you look at, compared to phones that are different as well as phones that are similar, it falls in the V-shape category. And graphs DO correlate to the actual sound you hear, at least the goldenears graphs do. They may not paint the whole picture, but almost all of it in almost every case. Especially the goldenears. Of all the IEMs I have used, in every case possible I compared their sound to the goldenears graphs, and in every single case the graphs almost perfectly matched the sound I expected from them. There were a few small sound properties that a frequency graph can't show, such as the separation and the speed, but overall the general "frequency" sound was extremely similar to the graph.
Anyhow, the point is, the ue900 is a nice earphone, it has a high quality sound, but it is not flat. You may prefer the non-flatness and find it more natural, realistic, pleasing... whatever. But it is not flat.
When thinking Ety versus a UE900. Think sitting in a 15ft square sound room with the worlds best 6" bookshelf speakers (ER4) versus four (4) 8" dual speakers in each corner of the room.
Which do YOU think might sound better?
Unfortunately, this is another irrelevant comparison. The speakers you are referring to could be v-shaped speakers. "Best" doesn't mean flattest. Some people prefer a different frequency response. If all else is equal I wouldn't call a v-shape speaker "worse" than a flat speaker, unless you are going for accuracy and neutrality. Also, I can almost guarantee the bookshelves will sound better due to acoustics, etc. But this isn't a fair comparison either. You're relating the size and number of a speaker driver to the size and number of an earphone driver. Who says the ety is equivalent to a 6" driver? Why not an 8" or a 4"? The acoustic chamber that is your ear also is much different than a room. There are a lot of factors, but basically the two technologies are similar but also very different.
Based on the quality of the ety, even if more drivers were necessary to get the utmost perfect quality, I can't believe that with the ety's 90+% accuracy rating (which i agree with), you would need any more than two drivers at most. So why more? Why four? (read my previous reasoning) :-P
