In my systems I've found using power conditioners restrict the sound in some way. I use a Nordost Qbase 8 (distribution strip) for preamp and sources. I also found that plugging my amp directly into the wall outlet (Furutech) sounded best. Sorry I can't help with the brands you are asking about.
Power Conditioner
I currently have a Torus RM20 power conditioner. Has anyone compared the RM20 to any Shunyata or IsoTek power conditioner? What Shunyata or IsoTek power conditioner do you recommend I compare to the RM20? Is it better to have one power conditioner for lower power components and a separate conditioner for the amplifier?
