The ER4P-24 is a short accessory cable from Etymotic that adds 75 ohms of resistance. This essentially transforms an ER4P into an ER4S (resistance being the significant different between the two versions).
The Xin SuperMacro amps have an optional switch that adds 75 ohms, serving the same purpose as the accessory cable.

2. Yes, send a PM to Vorlon1 who has the E500. I have used extensively the Supermicro IV with UM2, Ety ER4P, and the V-Moda. Excellent sound.
3. For this you should read the review Vorlon1 and I did a couple of moths ago at: http://www.head-fi.org/forums/showthread.php?t=203445
I prefer the Supermicro IV but any of the amps listed are very good. Good luck.
Xin definitely must have changed the default gain on the SuperMicro then; with my 1st generation, pre-tweak SuperMicro IV, you can blow out an eardrum with a 1/8" turn of the volume pot using IEM's. (I use an attenuator for safety when using IEM's). That's good news.
I still haven't sent mine in for repairs to the battery contacts/tweaks. I just can't seem to get the courage to ship it off, even though I have other portable amps to use while waiting for it to return. There is nothing in my inventory that can compare to the sound of the SuperMicro IV.
