Just installed these beauties between my DV-79 and AVR300 for CD input and all I can say is WOW . The sound difference between these and the old IXOS interconnect I had is amazing. The definition and different range of normal CD is fantastic it blew me away. I am going to replace the QED Quenx1 that I have currently as a digital interconnect with one of these cables too and see what difference it makes to the movie sound track. Would highly recommend this as an upgrade.
