Shunyata fluff is no step above the lower priced Audioquest. Try and get some Ansuz cables (the ones Michael Borresen directly had his hands in), if it fits with your wallet.
Audiophile frame of mind
It amazes me how I can justify my audio purchases and don't think much about them with something costing several thousand dollars. I know this goes with any hobby but I had a funny thought over the weekend. The last OEM part of my system that I have been considering an upgrade is power cables. I only have a couple random low end audioquest cables that I got as part of purchases several years ago. Shunyata recently launched two new lines, Gamma and Theta. I was thinking about the Gamma and to start with my monoblocks for the first 2 cables of a system that needs 6 total. It would cost about $1300 for those 2. That is the same cost of a nice Weber stainless steel grill with a side burner. I couldn't go forward with getting an official quote on the cables. Looks like I will be grilling in style this summer!
