I have decided that I am going to go with an Ultrasone. I had originally decided to go with the HFi-780, but am now considering the longevity of a proline headphone. I really like the velour pads and removable cable that the pro 900 offers; however my concern is that most of my mp3s are at 256 bitrate and the others are burned off of CDs at watever bitrate itunes compresses them at. Will the titanium drivers on the pro 900 make my recordings sound terrible? and will I need a small amp like the ibasso t3 or Cmoy to power them?
Thanks in advance.
