Been reading Reddit impressions, I really loathe how overhyped the ER2XR & how attacked the ER4XR is for being BA based?. If the ER5XR was just a ER4XR with a 6mm planar driver, Cue how Speed & detail suddenly matters to them. I still hold my view the HD600 is obsolete when the ER3SE & Sundara are a choice.
The ER3 is just a ER4PT refresh, You can even get closer with EQ if you like it being easy to power.
I just want to report back that I tried the 20 ohm resistor on the ER3SE. I have to say it definitely changes the FR and makes it noticeably brighter. Hence overall better details and more spatial sounding. Seems like indeed we can just buy the cheaper ER3 and apply this reisitor trick to get close to ER4 performance. Very happy with them so far!
