I would make sure that any active power conditioning device can handle the current required by the DSP8000s.

Five 150w amplifiers per speaker (specifications vary across datasheets) is 750w. Offering a generous 33% efficiency suggest they really need ~2250w. At Hong Kong's 220V standard that is around 10 amps per speaker.

See for example the Isol-8 power specifications which show a maximum of 10 amps across one or all power outlets.

When my second-user DSP8000s were installed one of them blew the plug fuse at switch-on as somehow an IEC cable with a lower value (3 amp) fuse had got into the mix. A 13 amp fuse was needed.

In the spirit of Spinaltap, I would like to confirm that I am not involved in the corrupt theft of a global sport.
