I've run a number of high quality amplifiers including Pass XA-60 mono blocks, Art Audio PX-25 mono blocks, and Atma-Sphere M-60 mono blocks into Running Springs and Audience power conditioners. Every time it sounded better running the amps directly into dedicated lines.
This may largely depend on the quality of your municipal power supply but in my case direct into dedicated lines was clearly superior.
YMMV
