As one would imagine with players and instruments cleanly placed in threedimensional space, the depth and width— but particularly the depth—of the soundstage increased significantly along with the blackness of the background.
If all of this were not enough, the Adept Response eliminated a slight, upper-midrange glare that had been present in my system and that was particularly apparent with piano music.
The Adept Response made a phenomenal difference in my system. Fundamentally, it improved the clarity of recordings by eliminating a previously undetected lack of definition, without introducing any brightness or most importantly any coloration. That is worth repeating. I did not hear any coloration from the Adept Response or any obscuring of the rhythm of the music. The Adept Response just made every recording I listened to more natural and in turn more musically engaging. Will the Adept Response make the same difference in other systems? I do not know. I suspect that, to a certain extent, the improvements experienced will directly relate to how corrupted your A/C supply is. But without question, this line conditioner is worth a listen.
