I recently got a pair of Sennheiser IE80. I love the sound but it sounds a bit muffled and everything seems to stick together. Therefore I am looking for a DAP with more power (budget around US$250). I usually listen to pop music so it would be nice if the vocal is stronger. What are the good DAP for this price range?
Also, I live in the UK so where is the best place to buy the DAP? (preferably online)
