I know this topic was posted just once almost a year ago and that was it for discussion. I need some help from jeff1225 since you have had an experience with what I'm searching for. Currently I have Soundsmith Norma—not happy with the sound. I'm looking for more details and transparency in sound and am trying to decide between the Air Tight PC-7, Shelter 901, or Lyra Delos. Do you still have the Air Tight Pc-7? Can you share your experience and any suggestion?
