Can flexible power cables sound good?

Just borrowed some hefty power cables from my locale dealer. The shop is closed because of Covid-19 so he borrowed me some very nice cables and a PS Audio Power Plant P20 to play with.
The PS PC P12 is simple not bendable and the same goes for many of the other cables.
That's a real problem for me. I don't have the space to move my rack out and rearrange all my equipment and electrical sockets to make room for such hefty cables.  

So are there really good power cables that are also flexible?
