Hidition announced their new CIEM: the Viento-R. Four drivers and two switches that control the timbre. I have only heard the UE18 demo about 5 times, but that is quite unlistenable to me and the Stage 4 is better. Nice description, thanks! That would be interesting to compare, the new VE vs. Rhines stuff. VE had an impressive build quality also, at least for the demos, but yes, Rhines is excellent!
