Hi, I'm in the market for a good CIEM for classical music. I'm about to close the deal in a pair of Heir 8A but would really like to hear some sugestions. I currently own an Etymotic ER-4 and a Triple-Fi with the Etys been my favorites. As a source, I'm going to pair it with my Ipod (as I had to return my DX-100) until the Hifiman HM-901 comes out. Any suggestions? Thanks a lot!
