Diapason, France. Reviewed and awarded a Gold Medal!
Without doubt, RD-3 works! The sound stage becomes larger. Also the sound becomes smoother and sound separation is excellent. The music flows even better. This is a must item for audiophile and music lovers
hifi & records, Germany
The sound becomes fresh and sound stage becomes larger. The sound becomes realistic. Very surprised by the effect of RD-3
