Cheap, good interconnects
In addition to the other mains cable thread where I recommend a 'cheap' mains lead, these are what I use mainly through my systems;
I have also re-wired a couple of turntables with those. They are well construced with a decent amount of copper and good shielding. Well made too.
There is no large perceiveable difference between the Profigold and for example a QED Reference. I very much doubt anyone would manage to tell them apart.
