I've found an earphone that can match / surpass the imaging and soundstage of Havi, it's made by an Australian company called Audiofly, (AF140) but doesn't come cheap at $350 AUD, it's mid-range tonality may not suit everyone either being quite dark. I think the imaging and ambience of AF140 is more involving than Havi, though we're talking almost $300 more money here and I can see many people still taking Havi.
On other fronts I also have Noble PR here with me as demo unit, while it's rather detailed the entire presentation is quite sterile in reference mode, unlike AF140 or Havi - Noble PR's overly analytical presentation sounds a little harsh all over but incredibly clear, though it doesn't have any true vibe or atmosphere like the other two earphones. it's a clear detailed earphone without much else.. All in all I honestly think I prefer Havi over Noble PR, this is from running test tracks most of the afternoon.
Take it with salt grains, preference bias, and possibly value for money perspective. but that's how I hear it.
You Havi owners are doing quite well, so be proud of the PRO 1.
