Has anyone used Totem URTH Power Cords or Blocks?

I was thinking of upgrading my stock power cords on my Arcam amplifier and CD player with the URTH power cords and block from Totem - it's the same as the power cord that came with my Totem Lightning Subwoofer. Has anyone had experience with these? Would it match with Arcam?

Thanks for any advice
