DCS Rossini Apex and Rossini Clock. I upgraded from the Bartok. There are layers of detail and nuanced dimension that I’ve never heard in familiar music. Live recordings are blowing my mind with stadium “being there” moments. The pedals in the piano - Jimmy Paige’s vocals on “Kashmir” at the O2 - Blood Sweat and Tears first album sound gorgeous. Zero fatigue - Worth every penny. It really compliments the ARC REF 6, ARC 160s and Sonus Faber Serafino’s. I love it…!
