A notable difference and improvement for these discrete opamps over other IC operational amplifiers tried in the Firestone Cute Beyond headphone amplifier, including the old time favorite OPA627. Busy going through my music collection of great diversity in genre and thus far it just seems to do everything right. It has brought to this little bedside rig of mine a certain synergy quite pleasing to the ear and silenced that little voice in my head responsible for compulsive upgrade disorder, as well as putting an end to my recent opamp rolling spree”…
