Quick question. Now that I have a DAP I can finally better appreciate the sound from my budget IEMs (and can also appreciate how bad the cell phone as a source actually was). I have a planar (Timeless) and a DD (FDX1), and would like to pick up a balanced armature design for comparison. So what would be a good choice for a budget, say under $300, BA IEM? At some point I may want to spring for a higher end pair, but first I would like to better understand the pros and cons of the different designs. Suggestions are welcome, TIA!
