No, they only work with AC.
I haven't seen any benefit running DC. I bought large Bridgewerks packs and converted my G scale years ago from a suggestion of better signal. They handle big consists with plenty of power in reserve. So I guess that's the big benefit.
The signal was the same with AC or DC for me. I believe it's more about good clean power and a lot of it.
