Recently went from the 20X,HO to the XX2. A giant improvement:
tighter base, smooth mids, clean extended highs. Much "faster" than the 20X. Music is more "right",I Could never go back.No tracking issues with a Graham Phantom arm. I had to have my Audible Illusions 3B modified with the John Curl Gold Phono boards-turn around time 48 hours.
