What David said. Dedicated line will cost you much less than any of the other devices, but it’s a foundation. Then you can decide on either Denali or other power conditioning devices. Typically they would work best in conjunction with each other. That’s not to say that Denali will not benefit without the dedicated line though. It will bring incremental improvements in SQ.
