Single ended interconnects between my dac to preamp and preamp to amp are Black Cat Silverstar 88. Unfortunately, they are no longer available.
Silversmith Audio Fidelium speaker cables.
Acoustic Zen mc2 digital coaxial cable.
Graham Slee CuSat50 interconnect elsewhere.
Just bought a Veritas Optimus 50 hdmi/I2s cable. So far, it's sounding quite good.
