No experience with re-generators. Just sharing experience, that if a much lower system noise floor is what you seek, the Decware conditioner delivers in spades. Shockingly good at subtraction without dulling dynamics. What one did not perceive as there, is removed for a blacker background.
I purchased one for a friend and without solicitation he independently expressed the same with his system. It replaced a Furman Elite 15.
Best of luck and success on your journey.
