Hey guys this is Ben
This is my first time creating a new thread so understand if i make mistakes..
I bought se535 and sold my um3x (cost me 100$)
i use ipod touch 4g which i just got and i think i want a portable amp to go with...
is portable amp necessary? also i was looking at RSA Mustang P-51 and Headamp Pico
which would be better for se535/
