I use a Torus RM20.

The main problem with power conditioners is filtering. Any impedance in series affects dynamics of the power amp. Linear power supply draws current in narrow peaks of big amplitude. Amplifier demand of 1A at given time will draw about 10A in narrow pulses from mains. Filters will cause big voltage drops and loss of dynamics. I use Furman Elite 20PFi conditioner, that in addition to filtering and good non-sacrificial over/under voltage protection has big capacitor that stores energy to provide up to 55A of peak current.
Ran the Furman with good results. Replaced with https://www.decware.com/newsite/ZLC.html which eviscerated it on all levels.
System is server, DAC, tube preamp, active ATC towers. All improved when run through it.

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!
