Running Springs Haley or Duke Power Conditioners

Thanks for your very detailed response. I'll probably go with a dedicated Duke for each Amp, Musical Fidelity KW's.
I'm a little concerned that it will be a little bright since the KW's are very revealing. I'm still playing with everything from interconnects, currentlly Acoustic Zen Silver Ref 2 all around. Have a paid of Cardas GR's to try between the KWP and the Amps. Tried AZ Satori shotgun cables to the speakers recently and did not like the loss in sound stage from the Audience AU24s I'm currently running. The BPT 3.5 is great with the front end equipment but with everything connected it's a alot of gear for one unit.

Thanks again

After reading the reveiw of the KW's in Stereophile, it appears that they are very sensitive to the quality of the power supply including the power cords. I'm sure you will be very happy with the neutrality of the Duke/Cardas combination as well as their ability to deliver high currents.

As for the brightness issue, I initially had that same reaction only mine was due to Audience AU24 interconnects. They sounded like they were over emphasising the high frequencies and putting too much bite on them. I changed them for a pair of Golden Reference IC's and wasn't pleased with the way the GR's rolled off the highs and killed the spacial detail. After changing to Cardas Golden Cross IC's, all the detail was present without over emphasis and it was very smooth. The soundstage opened up even more than with the AU24's. The Golden Cross were definitely keepers. It sounds like they may be a good match with the KW's as well.

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.
