Yes all 3 apps sound different, but I'm using eq on all 3 so of course there is some software manipulation going on. You still here the great separation on the other apps in fact even more so on the hiby app, but it's more spread out and the mids aren't as forward.
Neutron is really dynamic with a wide stage and aggressive treble, but they have the best eq.
I tried to emulate the Sony sound but I did that on my ap80, r3p and dx160 with mesb but I might try again- im sure it's possible to get close, I just couldn't get the seperation between notes that the Sony has on the r3p. No matter what -I could hear everything just a little clearer on the Sony.
Not that the r3p doesn't have great layering and space between notes, it's was just like a wall of sound compared to a whole of parts on the Sony. Both great, both slightly different.
