Yeah, I saw those posts. I'm just curious about the extent of the difference. Is it enough to say that the ER4 is more resolving than the ER3? I'm sure you guys have seen that the FR of the ER3XR can be made to be the same as the ER4XR with an appropriate impedance adapter. I'm wondering, if the FR is the same, whether the ER4/ER3 are essentially the same in their driver capability when it comes to stuff outside of FR (resolution, namely)
Going by john impressions, The ER3 is pretty much the ER4PT. I hear no differince when the treble on the 3SE is EQ'd to 4db with a 6K high shelf.
