You need to be careful with certain Linn components, especially disc players that contain switching power supplies.There has been numerous reports that after market power cords, even very well regarded ones can often make these components sound worse. I know Linn doesn't recommend the use of after market power cords for any of their equipment that contains a switch mode power supply.
Other than that, despite their large diameter the Shunyata power cords are very lightweight and extremely flexible. Never heard of anyone using a powersnake on a Linn before so I have no idea how it would sound.
