I have a Rega Brio-R amp and Apollo-R cd source, and looking at a new 2m basic level of power cable upgrade for both of them, with Australian plugs. Which of the Merlin Tarantula MK6 or Wireworld Stratus 5 would you choose? Both can come with Australian plugs, and have good reviews, Wireworld especially. Alternatively I could go with the rather more expensive Rega mains power cable designed for their Osirus, but it seems to come in 1.5m only, and I need 2m - and cost starts to come a factor.
