Do I need a power conditioner?


I’m in the process of dropping a dedicated 20 amp circuit or 2 into the music room.
So if I have a dedicated circuit for the amp, and a dedicated circuit for everything else,
is a conditioner useful?
I have several fairly decent systems going that I tweek and retweek.
Just got around to upgrading cables. Avoided conditioners because, in general, they dampen the presentation.
Was using a PS Audio PPP for low power components. But fell for the Shunyata spiel.
Plugged in a Hydra 4 with a Python Helix and was very happy with how it cleaned up the Zu Druids.
Seems high sensitivity speakers maybe reveal the grunge also.
Moved it to my system with the Martin Logans and the presentation seemed a bit lean and just a bit lifeless, using just copperhead cable to Hydra. (using all Pangea to get from the Hydra to other components.)
Then I put a Black Mamba from Classe amp straight to the wall and Wow! Single most significant tweek ever for me.
So I’m thinking, maybe I don’t need the Denali I ordered if I just use a couple dedicated circuits and some Shunyata power cords everywhere.
Opinions?
Thanks. :)

I want to correct the above statement I made about how the MC-6 Hemisphere works. The MC-6 Hemisphere does work on the same principal as the MC-6 however, the parts are upgraded and there is an advanced waveguide system along with a ceramic-tempered, hard, anodized aluminum receptacle mounting and bottom plates for vibration-resistant mounting systems on the internal waveguides and receptacles.  

Hullo:
I have a BPT2.5 balanced unit that I got used here on Audiogon.  It came without any instructions at least to me.  A question for anyone who can help.  Is it safe to use it to power Synergistic MPCs and FEQs which have two pronged plugs but have separate 3 prong plugs solely for grounding that must go into a separate socked altogether?

Thanks for any help.  Perhaps I should contact Synergistic?
