I myself have owned the HEJ900s and can say they have amazing bass that is clean and controlled. HJE900s mids are a tad bit recessed but just turning up the volumes a little bit more than normal completely fixes it and with the volume turned up the mids are amazing to.
The ER-4 is analytical, the DBA-02 is not. Analytical is very different than neutral, the SM3 which is rather warm is also said to be neutral. Also, I read a review yesterday saying the DBA has more bass than the Q-Jays (which the OP has and likes the bass of) so the DBA-02 and CK10 are not totally out of the question. In fact, his Q-Jays are rather similar to them, so I would think that he would be fine with either one. Those three armatures are all the most similar to his Grados in sound signature. The Panasonics will have a lot more bass than you are used to, so I would make sure you're ready for a lot more. The Coppers will have more as well, but it's a different type of bass. It's deep sub-bass that you really feel in your head. I have the DBA-02 and the Coppers and I find the Coppers to have a lot of bass. There is speculation that the way you burn in your Coppers determines the final sound signature. That thread popped up after I burned mine in so it was too late for me, but it seems that mine turned out quite bassy. I would probably like them more if they turned out more neutral.
I won't post any gripes since I'm the man behind Bugden Audio and therefore sell the DBAs.
Quick comparison: The Coppers have a bit bigger soundstage. The Coppers have more bass, and the bass has more impact. Both are involving but in different ways. The Coppers are more laid back and are smooth, almost like liquid. I can imagine these being nice for jazz etc, although I do not listen to anything other than rock for the most part. The DBA is more forward with the energy in the mids and highs. Bass is there as the recording intends. These are neutral, so nothing is there that should not be there and nothing is lacking that should be there. These are also revealing, so crap in = crap out, and you will hear the characteristics of your sources. The DBA has the edge in sound quality overall, whereas the Coppers are a more relaxing listen. One would not be paying as much attention to the detail with the Coppers.
In terms of involvement, I liken the Coppers to rocking out while relaxing on a sofa (as much of a paradox that sounds, just imagine someone sitting down and headbanging), and the DBA as being in a rock concert. The DBA is more energetic sounding as an armature driver, and the Coppers are smoother sounding, more relaxed as a dynamic drover.
The CK10 sounds similar to the DBA. I have not heard it, but they are quite similar from all other reports. My estimation (from all that I have read) is that the CK10 is about as warm as the Q-Jays, while the DBA-02 is a little bit warmer from reports I've read.
I can't suggest anything in particular since the DBAs are an option, but either one of the three I went over are an upgrade to your Q-Jays. The question is mostly how far off from that sound do you want to veer.
