was thinking about the RA plus, but it says that its up to 300 ohm and some say it can't power the zen 2.0 efficiently enough, although, wild lee said on facebook that pluging it in to a wall socket will almost double its power
I am more of planing ahead of time, I'm not actually going to buy an amp anytime soon, its in my nature to plan way ahead and to over think things way before I actually do or buy something, (except for the auglamour rx-1, I got on that hype train as soon as it left the station )
My situation as well. I'm considering O2 amp. Transparent, cheap and can drive up to 600 ohm (hopefully, with authority)
