Hi Anthony,
Our products are all designed to handle normal mains supplies without being affected by the various dips, sags and glitches that are always present and we would advise that our units are used directly plugged into a normal wall outlet.
There should be no need to use a mains conditioner or regenerator and there is always the possibility that using one could adversely affect the performance of a piece of audio equipment instead of improving it - of course we are aware that people do like to experiment and tweak in this hobby and should you feel that the performance of your unit is improved by using it on a mains conditioner or regenerator then it is totally your prerogative as to whether you use one.
Similarly surge protection is generally quite ineffective on most consumer grade mains filtering devices so again this is a function which may not be of huge real world use (certainly most surge protection would be easily overwhelmed by a nearby lightning strike).
So in summary I would recommend using any of our units plugged directly into a wall outlet but the option is there should you feel you wish to do otherwise - however be aware that should any damage be caused to a dCS product by a faulty mains conditioner or regenerator then it wouldn’t be covered under warranty.
Best Regards
Phil
