Stock power cords work, some folks like them, others try DIY, and then some prefer the more exotic varieties.
The only way to know what suits you is to try some.
In my expereince,I haven't found a product that didn't benefit from a better power cord.
So even though my amp only puts out 2 watts, it gets it's juice from a Python CX,Hydra 2,30 amp dedicated line of 6 feet from the panel.
I think the fewer the watts, all the easier to really make them sing, or screw them up.
