I'm about to buy the Pico but have been reading a lot that the Fiio E9 drives the K702s really well...Should I even be comparing these two? The Pico is about $250 more. I also will be using this to drive my other cans, AKG K272s, Beyer DT-831s and Sens HD580.
So like I stated I'm ready to buy the Pico - just got doubted a bit after reading abou the Fiio E9 and its ability to drive the K702.
Convince me that the Pico is the way to go please.
