So ive finally broke into getting a decent pair of IEMs ( RE0 ) and have some Sennheiser Px360 on the way. Now i am wondering if an amp is needed or not. The RE0 sound pretty great alone but i have a feeling that the PX360's might need a little extra.. push. (maybe not idk yet.) like i said im trying to find out what amp would be best for both of these sets. If it helps at all i listen to mainly rock, all types really. And am using the Ipod touch 4th gen.
 
I see a lot of people talking about the Fiio brand items and how good they are, but if anyone has any input on other brands they are very welcome.
 
thanks in advance.

32ohms and 110db SPL, seems like the PX360 is intended to be used unamped. Unless you are use some really bad source like a cheap onboard soundcard, you should be fine
