Power Cable Suggestions.

AQ power cables didn’t do much for me in a long run. Tornado, thunder and hurricane. They colored the sound. 
I use Kimber PK10 and PK14 Ascent throughout my system. Nothing stands out - very balanced and natural sound. 

Try MAZE audio, or Pinetree audio, good cables at prices that won't leave you broke.

I bought Maze Audio Litz with Billet plugs early on, when my system was upper mid-fi. They are 8 or 9 gauge, have excellent neutral sound with excellent noise rejection. Now that my system is high-fi, I continue to use them as they scale very well. 
Gemini verdict: 

The Maze Audio Litz Power Cord with billet plugs is a masterclass in straightforward, effective audio engineering. It bypasses esoteric marketing in favor of proven geometric noise rejection and rugged, high-contact termination. If you are looking to unearth hidden micro-detail, expand soundstage holography, and lock down mechanical vibrations at the AC inlet, it is an incredibly robust, highly recommended upgrade for any critical listening setup.

Ice age audio - Frankencable. Do yourself a faver and test them.
