Power conditioner


I am looking for a power conditioner for my sys
Amp Rogue Zeus
Pre amp BAT 32SE

1-Could you recommend for some?
2-Should I plug the amp to the power conditioner or not?

Thanks

I have tried the Torus RM20, and now own the Audience AR6, and previously used a Panamax 5500 (now relegated to my HT system). The Torus was a significant upgrade from the Panamax but when compared to the Audience there are noticeable flaws. The Torus adds too much bass which isn't noticeable until you try other power conditioners. the Audience is much more balance with far less tonal characteristic than the Torus. The music is more natural. i would only recommend a Torus if your system is a tad on the lean sounding side.

Tried SR, Audience, Torus and a few others and Running Springs was better in my system.
