Favorite cable Brand ??, That is going to depend on the your units and manufactures .Cables sound different with different companies .

High Fidelity and Transparent

In my system I have tried budget (relative I know) cables such as Anticables, Audio Envy, and Cullen, and high end cables such as Stealth, Iconoclast, Silversmith, Silnote, Purist, and AQ. These are my favorites:

Power cords:  Stealth Dream V10 (highend) and Cullen Crossover II (budget)
Interconnect:   Iconoclast UPOCC (highend) and Anticable Ref. 3,1 w/double-run of conductors XLR (budget and so good)
Spk. cables:   Silversmith Fidelium (highend) AQ Robin Hood (2nd). Sorry, not budget here. 
Digital cable:  Silnote Orion but I am waiting for AQ Firebird48. it is a brand new model and 7 weeks of waiting so far.
