So, as I said in prior threads, I ordered a pair of Denon AH-D2000s. Now, as my main two sources, I'll my using my iPhone, and a Creative Zen (Micro? Its the credit-card sized version.) Anyway, I tend to use the iPhone more since I don't charge the Zen often enough. So, I don't know what's important to do next. I've seen a few of the portable rig threads so I'm kinda confused. Right now, I only want to spend another $100 for a amp/amp+cables. I've seen the dock line out plugs without cables ($50 seems like a lot for one, is there a DIY out there?) and after googling Black Dragon Cables I found out about moon-audio.com it seems recabling makes a difference for any headphone, even if they cost $20. So, thats my question, should I pick up a $30 CMoy or a FiiS' E5, and some cables, or just get a better $100 amp and wait for the cables? I need specifics on where to look etc. I don't mind reading, and I don't understand a lot besides good audio is a good thing. So, help! Please!
