Class D and Power Cables

Most of aftermarket cords are made the way they divert the sound and color it to make sure that consumer hears differences. They've been introduced into high definition audio as another layer of brainwash and source of ez money.

My experience with the d-Sonic amps I bought early this year is that they are the most grateful equipment I have yet encountered. Nearly everything i did to or for them paid out in improvements in sound. They improved substantially when given better cables. I started out with diamondback platinums, a decent entry level cord, but they really came into their own when I installed pS-Audio's former TOL Pc he extreme SC that retailed at about $1000/meter. These can be found here on agon used for under 400 now. They also performed nicely with an older pair of Synergistics research X2 Master couplers.

FWIW, I got the biggest improvement in the amps' sound quality by putting them up on isolation platforms. I got a huge return for around $200. Because they are so small, they only need small maple blocks ($90 at dawnsplatforms) and two sets of mapleshade isolation blocks ($50) and some used brass footers from the web ($60) made a bigger difference than going from the diamonbacks to the PS Audio power cords.

I own a pair of Red Dragon M-500 Class D amps. The sound of the amps was greatly improved all across the board when I started using the Lessloss DFPC power cords. It was a night and day change for the better (for me and my tastes)
I also have a Audio Research 150.2 Class T (Tripath) Amp in another system and I replaced the stock cord with the Lessloss DFPC Signature Power Cord and again the sound and performance of the amp improved tremendously. The improvements that these cords made are not subtle. Now when I used either of these cords on my Tube amps (Quicksilver V4's) the results were a different story. I much preferred the stock cords. That holds true for my tube preamp from ARC (SP16).It seems to me that it's all about synergy with a certain product so if you can, try before you buy. In my experience the Lessloss cords worked miracles on the SS Class D and Class T amps but not so much on most everything else I tried them on, including a DAC (Benchmark DAC 1).Some products when mated with other products really click for the better, and only your ears can decide what sounds best to you. These aftermarket power cords definitely do something but it might not be something that you like. Good luck in your search for the right PC for your amps.

I have tried Clarus Crimson power cord on both Bel Canto and Jeff Rowland class D amps with amazing results.

This is probably an obvious answer. Why not call W4S and ask Clint or EJ? If you like the amp I'm sure they will give you a straight answer.
