Hi, I believe that we DID do this actually at the show. At shows, where power is SO BAD, I will do this as long as I know the power conditioner or isolation unit that I am using will be lossless. In the case of the 1800, I agree that there should be no problem in doing so. We had GREAT sound at that show, with Deadalus speakers, Skogrand Cables and ModWright Electronics! Truly great sound at that show!
With regards to the Deep Core, I am just hesitant until I test it further, insuring that the Deep Core itself will not current limit and can handle this.
If the Deep Core can be used in this application, then it should be ideal. I just can't confirm this until I test a current version of the Deep Core.
Thanks,
Dan
