I'll try to answer from my experience. The t8ie mk 2 is newer where the Dita Truth has been around for a couple of seasons now. I think there is some initial excitement about the t8ie mk 2 because the original had some issues (cable and build if I remember correctly). I have auctioned the 1st gen t8ie a couple of times and really liked the sound (very detailed and similar to Beyer's Tesla on ears specifically the DT 1350 & T51p) but felt the form factor has on the small side and I was not able to get a good seal. I've only recently become a convert to the Dita Truth Answer which replaced my CA Jupiter. The Answer requires a little more time tip rolling but over all it is an amazing sounding iem despite not being the newest or latest iem on the market. I'm sure once the Dream is released you will see more activity here as some revisit the Truth.
