Hey guys its my first post although Ive been reading the site for a few months.  I own a set of GR10 and a pair of hd25-1II.  Im looking to provide the best quality to both headphones using my GalaxyIII and my macbook. Looking for something under $500. Also what power supply is best for these units? Battery, rechargeable or plug in the wall type. I listen to all types of music at moderate levels.  I saw a unit i was interested in, but it says battery will eventually need to be serviced at the factory after around 300 charges. Not interested in that at all. Anyway hello from New Orleans and thanks for the help

A good option that is easily within your price range is the iBasso D4 Mamba. I feel that the best would for it to charge and play while plugged into your Macbook.
