Upgrading PS for CA DacMagic

Greetings everyone. I'm considering upgrading the power supply on my Cambridge Audio DacMagic. I've done a bit of reading/research on the subject and most of what I have learned is from the UK. There are a few popular inexpensive upgrades widely cited that I believe can only be used in the UK.

Suggestions for upgrading this PS in the states? I'd especially appreciate hearing from folks who have actually made the upgrade.

Thanks.
