The 64 Audio Trio and Fourte are both being dropped from my top tier. Just like the Sony EX1000 and 800ST were dropped from A+ to B 2 months ago. Memory, worse than a “Demo” but both are not ideal. Different evaluation style, higher expectations, no nostalgia (e.g. EX1000). I was wowed by them but likely because of being unique instead of great. The Nio is also too smooth and warm. U12t is in fact best product they have made that I have tried. Both are for sale $1,800 for TRiO and $2,000 for Fourte which has no box. That’s why not $2,800-$3,200. While the Legend X is also a specialty IEM like these two, it matches my library while these would get less play. They need a new home. I will do a vid.
