I got my Audience Adept Response and like it. The top end of my system is smoother and I notice more detail. The bass may be a bit tighter. Most reviewers say that the tonal balance does not change much but some say the Adept Response may give you a lighter sound, I had the opposite effect where there seems to be less energy in the high end and the sound may be a touch warmer. The main difference is I notice the music more.
Thumbs up!
BTW FWIW read the recent rave reviews on this model in TAS Stereophile and a few other publications. Most say it is the best out there...
