power cables where do I start?

Signal Cable is a good affordable place to start. If you can find an Audience powerChord used at a good price, it's my go-to cord. It's not the best cord for every situation (no one cord is) and the degree of improvement varies, but it's extremely consistent. At its best (especially power amps) it can be transformational.

Signal Cable "Magic Power Cord" very nice for the money which is not a lot, very thick and stiff though and heavy so add a couple xtra feet for whatever u think you'll need.

 Try to diy some powercables mede from 12awg solid core. It might open your eyes

I use hospital grade power cords ($20) and a Furman 15i power conditioner. It's all about clean power to protect your investment. 

Stranded wires can`t give you clean power
