Amplifier advice for Cowon J3
I am big fan of good sounding and a bit stylish audio equipment. I have been using Cowon i7 with Audio-Technica ATH-EW9 clipons for few years, but few months ago I lost (well, it got stolen, but result is the same) my beloved i7 so I bought myself Cowon J3 to replace it. I am more than satisfied with J3 + ATH-EW9 combinations. But since I need something for louder environment, I am getting Monster Miles Davis Tribute IEMs. Eventhought I dont have any problem with ATH-EW9 I am not quite sure how it will perform with MMDT, because I found somewhere that they are 286 ohms (dunno if I can trust this, but there are no numbers on Monsters site unfortunatelly), which is already a bit high (much higher than 28 ohms of ATH-EW9). Since I have basically no knowledge about amps and how exactly they are affecting sound quality (well, I am not that naive to think they will turn every #$*& into earcandy...), so my question is whether I need an amp for this (J3+MMDT) and if yes, which one would be the best. Budget would be around 150$, any help and suggestions is appreciated.
Thx in advance
