I own three Haley's. I use two in my Audio system and one in my Home theater system. Fantatsic products! For years I tried all the highly touted power conditioners on the market. They either colored the sound or limited dynamics. The Running Springs Audio power conditioners don't seem to be plagued by these problems. They are extrordinarily neutral and capable of delivering instantaneous current without limiting leading edge or dynamics. They are also reasonably priced. With the high power consumption of your amplifers, I would choose the Duke's. Also, the Running Springs Audio Special Edition powercords (I own 10 of them) are the best kept secret in high-end audio. I hope this helps.
