What is an excellent power cable?

@xenon Many excellent choices within your budget specs.

+1 re. @nonoise ’s recommendation to consider Triode Wire Labs.

You may also want to consider Audio Art Power Cables in addition to the ones other members have already pointed out.

All the best.

There are just so many. It seems daunting.

@xenon There are many, many options. But it doesn’t have to be "daunting."

I recommend borrowing two or three from your dealer or an audio buddy or from a lending program like the one offered by The Cable Company.

None of us can tell you what you will prefer and what will work for you in your system. The only way forward is to experiment and learn and come to your own conclusions. All the best.
