First listen, and first CA IEM, quite nice and liking the tuning. They sure are sensitive to amp hiss. I take it, much the same as Andromeda, and that this is the lowest impedance IEM I have ever listened to myself. Substantial hiss on Mojo 2, RS6 (lesser), and C9 (fed by Mojo 2 or RS6). Basically fixed by an IEmatch without much impact to dynamics (very slightly noticeable if I A/B) or FR to my ears. Just need to get a 3.5 IEmatch in for 1 less adapter with the Mojo. It's interesting how much a difference from 16ohms and high sensitivity of a Zen Pro to 12ohms and lower sensitivity of the Fathom leads to such a difference in the perceived noise floor. As well as how that seems to be inherent to CA's all BA designs.
It's sticking around for now. Just wanted to put that out there in case someone was curious if that was different.
