The Walker Audio Talisman is in use here. Both on my system and on the systems of some other audio friends, I hear pretty consistent and repeatable improvements when the Talisman is used: greater clarity through the midrange particularly noticeable in the harmonic overtones on strings, blacker backgrounds, often a top end that sounds more extended and pure, better delineation of a broader, deeper and more layered soundstage. The difference is subtle, but very defintely audible and repeatable across four different audio systems.
