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

My suggestion is to get a Furman PST-8 for all your non-essentials instead. Excellent surge protection and will keep the noisy appliances out of your cleaned zone.

While power conditioner quality may vary, it IS possible to inject new noise after the conditioner.  Wall warts, TV's, network gear, etc. should be outside of your boutique conditioner.  The Furman provides both excellent noise filtering and surge protection, not to mention convenience. :)

@erik_squires that was my other option. Wondering if the blue ray disc player could be within the hi-fi grouping. 

I'd try it. :)  The real issue is how much noise the power supply puts out.

You can use a power strip connected to your Shunyata PC. I am doing just that for the powered woofers in my Golden Ear Triton Reference speakers. I have a Hydra 4 with one speaker plugged directly into it. I am using a power strip plugged into the Hydra for the other speaker because the high end PC I am using wasn’t long enough. No difference in sound and Gabrial or is it Caleb at Shunyata told me this when I called to inquire. It has been this way for 7 years. I also charge my iPhone & my iPad onn that strip at the same time (2 wall warts) while the system is playing with no ill effects at all and no noise when plugging and unplugging the devices.

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
