I cannot stress this enough: Trifecta does not play nice with the bulk of my library, but it is not, by any means, a bad IEM. Honestly if
@fejnomit hadn't bought it, I might've held onto them (and this morning I was genuinely considering it). What CFA has done goes contrary to everything traditionally "audiophile", and I'm certain that's what some of the vitriol in other circles has been. Where it works, it works really, really well, but I wouldn't classify it as "safe" a tuning as, say, the rn6, or even the xe6 honestly.
This, for example, is stupid fun on them:
I think those saying it's one of the worst audiophile IEMs they've heard is a fair assessment, in the sense that, yeah, if you rate music as "this should always sound exactly like this and that's the benchmark for audiophile", and then something comes along and sounds different, you're gonna have a bad time. In a world where everyone else has gone right in terms of sound signature, CFA has gone left, and that's intriguing to me.
