Running an Isotek Aquarius for all gear except amps and subs. Highly recommended. The change in sound quality was like a component upgrade. In my system/to my ears, replacing the stock Isotek Premier power cord with a Venom HC and subsequently an Alpha NR v1 power cord provided another noticeable improvement in the sound. I was running the Alpha direct from wall to amps (these include a Hegel H200) but now use a Delta NR v1 on the amps. Tried Pangea AC9 and Cullen Crossover (v1) but prefer the Shunyata cords,
