Fiio Reproductor Hi-res M21

I am a novice to DAPs but am interested in Hi-Fi systems and quality audio. Until now, the price of some DAPs has put me off and I saw them as devices more relevent to someone who travels a lot. Anyway, I decided to get a FiiO M21 and have connected it to a TEAC network player using a decent Bluetooth receiver and am so far impressed. However, I am most impressed with the speed of the delivery - ordered on a Wednesday and received on Thursday morning. That's hard to beat.
