Hi Mark. Thanks for nice comment.
About Xindak power conditioner - I testing this conditioner in my system some weeks. This Xindak have isolation transformer+filter for low power equipment and only filter for power amps. And I must say, that I heard more clean sound background. More bass power. And for this price its very good equipment.
But I testing Isotek Nova. And we here(My hifi friends) compared it with Accuphase PS-500. And this is my future upgrade. My very, very big recommendation.
