Yeah sorry guys, been in the States since yest with 5 hour difference.
I have only heard the Bax with the Encores and love it but am also curious since K10 changed massively for the better with a Rhapsodio silver/gold.
In all honesty ive only been using the A12 since i got them,been burning the ZX2(about 140 hours so far).
I am in love with both Encores and A12 and they are quite different and both absolutely brilliant!
I am trying to listen at the mo,with an A to B on ZX2 which is not the best way but so far once you get past the fit feeling in changing b/n the 2 id say Acs are less pronounced in the treble and very refined up there whilst the A12 pairs to a bit more extended but more in your face kind a top with zx2.id say its a typical for at least 2 ba drivers dedicated treble kind, I am waiting for zx2 to get to over 200 hours to see if itll improve.
Mid bass is very pronounced with Encores whilst A12 feels less body yet it has some of the deepest sub extension ive heard in an iem.
Ill post more as i go,sorry im jumping from wifi to wifi and having far to good a time drinks etc at the mo
