You didn't say what sound "tailoring" you may be looking for.
I tried numerous power cords on my hybrid integrated amp, and finally settled on an old school Tekline silver power cord - which gave the sound a bit of a sparkle, added bass, and a jump in 'life' overall.
My tube components just love foil power cords like the Elrods for example.
On the other end of the spectrum, you may want less sparkle, more mid-bass foundation, etc. In which case I would look at something like Sablon and others.
