System assembled; only a final decision about speakers remains

I have seen that advice and I’ve also seen many people say that they would never take that risk with their equipment especially given the crap that’s on our electrical lines or the possibility of an electrical storm. I would be worried that I would forget to unplug it or that the storm would happen in the middle of the night.

FWIW, in my particular case I believe that the quality of my incoming AC is relatively good, as there is no commerce or industry within more than two miles of my house and nearly all of the town is zoned two-acre residential. So I’ve chosen to adopt a "less is more" approach to power conditioning (no regenerators for me!), but without compromising the protection of my system.

What I’ve done is as follows:

-- Installed an Audience aR2p Surge Suppressor/Conditioner ($695).
-- Installed a Wiremold UL210BC Power Strip ($71) to expand the two outlets of the Audience to 10.
-- Plugged a Shunyata Venom Defender ($225) into one of the outlets of the power strip, to attenuate noise that may be generated by digital components and the power amp and fed back into their power cords, from whence it could potentially couple into other components.
-- Installed a single 20 amp dedicated line, which powers the entire system via the Audience.
-- FWIW a "SyCon" whole house surge protector was installed by an electrician at the service panel, when I had him replace the entire panel a few years ago.

As I said I’m in an area that presumably has relatively clean power, so this approach may or may not be a good one in other circumstances. But it works well for me.

Best regards,

If you think a MOV device degrades the sound you could use something like ZeroSurge. 

@almarg Thanks, Almarg. I’m curious — why did you choose to run the two-outlet Audience Adept aR2p unit into a multi outlet power strip and then address that with the Shunyata unit to attenuate noise? As the Audience Adept product notes, "the aR2p can provide power conditioning for an entire audio or video system albeit without component to component isolation featured in multi-outlet Adept Response conditioners."

In other words, why not buy a unit which performed the functions of the Audience and the Shunyata combined — a unit which also separates noise from digital and power equipment? Were you economizing or is this a superior way for some reason? [I think I just answered my own question -- the aR6 from Audience is $3495. So it seems you found a way to get the benefit using the 2 outlet unit with a power strip?]
P.S. I found a good review about the Audience here: https://www.stereophile.com/content/audience-ar2p-adept-response-power-conditioner-sweepstakes
