I’ve also done a little research on the Deep=Core but I need to do a little more. I’m guessing you have to match the models so they align.
You're welcome. Depending on the size of your system, the 1000 might be all you need.. If you have a high-current amp it may be best to plug directly into the wall
1000W is a large transformer and a power cord for high-current components should be used to the receptacle. If you can get Walter's Gold power cord for $99, that would be perfect. I have one and it's excellent quality, it powers my DeepCore.
As far as matching the DeepCore 1800 with your 1000, talk to Walter. Deep=Core is designed to work with different brands and sizes of power conditioners.
