Hi, I am looking for suggestions for a portable headphone amp for the Etymotic Er-4p IEM's (Apuresound recabled) through an iPod Classic. I need to stay under $500 for the amp, and under $180 for a quality LOD.
So far, the ones I have come across are:
1. ALO Rx Mk2 ($449) and the Triple Cryo LOD ($175)
2. HeadAmp Pico Slim ($399) and Right Angle LOD from Headamp ($129)
I would greatly appreciate either confirmation of one of these two, or new suggestions.
Thanks in Advance.
