My understanding is that with 220v, your equipment will be sound more pristine (lowered noise-floor, etc.) and run a bit more efficiently or effortlessly.
Since you would or should be running dedicated circuits/ lines for each component, then those components requiring 220v could be wired as such by an electrician.
I think the Nuforce Ref 9 and SE amps and a few other 110v components can also run at 220 volts without any converters or component rewiring. But you definitely should confirm before attempting such endeavors.
Personally, I would like to convert all of my components to run at 220v because I think the potential for sonic gain could be a little startling.
-IMO
