Is it fine to connect a power strip with A/V to one input of the power conditioner?

I'd generally avoid plugging a surge protector or power strip into a nice conditioner. This is for a couple reasons. First, there is a solid chance it will insert noise into your signal, but second the draw on that one outlet may end up being more than is intended. You're gonna want that power amp to have lots of current available and by sharing it's outlet with other items you may end up choking it a bit. I fact, there are those that done use conditioners for their amps at all because the circuitry tends to limit power a bit. Just my $.02

Great discussion.  I'm a newbie, so what's  a "wall wart" ?

@max_sansui 

A "wall wart" is a colloquial term for a small, external power adapter that plugs directly into a wall outlet, essentially a transformer box with a power cord that provides electricity to low-power devices like cell phone chargers, routers, or electric toothbrushes; the name "wart" is used because of its bulky, unsightly appearance protruding from the wall socket. 

@rmdmoore after some reading I’ll plug the power amp straight to the wall and limit the conditioner to key sources and preamp. I have two direct lines on the wall, one for the conditioner and the other will be used for the power amp. A standard wall socket will be used for tv, blue ray player and (sigh) router. 

After two warranty repairs for my Samsung TV, maybe it’s purely coincidental, but after getting a power conditioner all my electrical gremlins went away. Unless you can hear the noise, I’m plugging my TV into some kind of line conditioning. Remember these are smart TVs with little computers in them and anybody with a serious computer is gonna have some kind of line conditioner on it.
