In my "big rig" all line level interconnects are Cardas Clear Reflection; this has replaced a mix of older Golden Reference and Clear Cygnus. Balanced from DAC to pre, otherwise RCA.
The Clear Reflection cables are perhaps (definitely?) just on the warm side of neutrality, but, at line level, seem to do no damage.
The phono connect is a Transparent Super Phono. I tried Cardas in that position but the sound seemed to lose air and space.
USB is Cardas and Ethernet cables are whatever - my Esoteric K-01XDSE DAC seems to be completely insensitive to its digital input provided the data is correct. It is my experience that today's well engineered DACs are relatively insensitive to cables, unlike the situation 30 years ago when jitter on the input to a DAC was a serious problem.
The clock cable is a 10 giga Hertz bandwidth broadcast level transmission cable.
Power is from a Monster Cable surge protector/filter. Amplifiers are connected via MIT Z-cords, other equipment via 16 ga. "hospital grade" power cables. My equipment is on a dedicated line from the panel, I am the only house on the line from the 13.8 kV (I think) transformer 100 feet from my house.
