The Furman Elite-15 PFi is a quality unit with all the good stuff and is an easy recommend. Series-mode surge suppression, linear filters and Power Factor technology. As kijanki indicated above, the dynamic current demands of power amps can result in reduced dynamics due to losses associated with filter impedance. The Power Factor technology addresses that problem by providing energy storage. Audioquest offers the Niagra 3000 for $3000 if you feel in a spendy mood.
Be aware that the cheaper power conditioners/suppressors do NOT have the Power Factor technology due to cost constraints. Using conditioners like this for a large, current-hungry power amp will likely prove disappointing.
Good luck in your search!
