Hi all. I'm looking for a great DAC/Amp combo to pair up with my Cowon J3 and my W3's. My budget is 700 USD... I know the W3's are a low impedance phone but I really want to "make the most of them" and get the best sound possible. I dont want just a "slight" difference I want a huge difference because I'm spending so much. Especially after I convert the USD into my currency... Which is NZD -.-' Portability and durability are huge factors and hopefully none of them are much bigger or much heavier than the J3 itself. I usually listen to music like florence and the machine or a state of trance and sometimes maybe some post hardcore or deathcore. Ive been leaning towards the Pico Slim but dont know which DAC to pair that with. Also which LOD should I get? Ive been looking at this: http://aloaudio.com/compact-right-angle-sxc-22-fep-mini-to-mini.html Honestly I dont know what the differences are in each of those EXPENSIVE as cables but I know some of them are copper and some are silver and some are like SXC 22 or 18. Please help me out. Oh and how would I keep all the units safe? Like prevent them from slipping out of those straps or velcro tape? Thanks so much head-fiers.
