I am using Shunyata Anaconda CX AC cords on all my gear including the Benchmark. The AC cord does make a difference, unlike what the engineers at Benchmark are claiming :-)
Digital and video gear operate on a dedicated 15 A circuit and filtered with a Shunyata Hydra V-Ray II power conditionner. My Krell monoblocks have a dedicated 15 A line each and connected directly to the wall outlet (no filtering). All wall outlets are Furutech. A good wall outlet makes a difference, mainly on the quality of the bass.
