Could you elaborate more on comparing the Etymotic with the AT? What about soundstage and attack/transparency?
"Always trust an Ety guy"
Well, first of all I think that Ety are unique and there are no actual competitors to them not just among 1-2 driver BA IEMs but in general.)
I would not recommend to listen to ls200 right after the SR, let your brain forget a little bit how ety sound)
Otherwise they sound darker, bassy with the highs rolled off. So SR sound more transparent, more resolving, more detailed with more highs, faster bass attack.
That was my first impression.
I waited for 1 day and tried the ls200 for the 2nd time. And that was the right thing to do.
I found them performing very well, very good soundstage which is wide enough, plenty of details, highs are well extended, bass is tight.
And you can listen to them for many many hours without and fatigue.
SR to me is more analytical sounding reference but the ls200 is my on-the-go IEM.
Ety pair with my DAC/Amp only, LS200 pair mainly with my DAP but they sound even better with Vantam.
So they are different but I like both. I can listen to ls200 for 3-5 days without touching the ety sometimes.
But when you get back to ety you undertsand how perfect there are))
