It should be pointed out that Kal Rubinson long ago recused himself from making comments about cables. If you read between the lines of what he has to say on the subject you can deduce that he knows...

It's so hard that it's impossible. You can stiffen a DC supply with autosound by adding caps paralleled across the power supply cables , but not an AC supply. I know that you know this, so you get a...
