Yes. Check the other forum as well.
In my opinion the power cables have more impact on sound than interconnects. Gigawatt is not known in the US but their conditioner seems very good. I bet that cables like Shunyata Omega or Synergistic Research SRX or Nordost Odin 2 or the expensive offering from Ansuz or my moneoone Supernova will be much better than LS-2 from wall to your conditioner. It will likely be a cheaper upgrade with more impact than the IC.
