Power conditioners and wall warts

Great topic. I, too, would like to hear opinions.
In reply, I think there are many who are replacing wall warts with Linear Power supplies, to great effect.

Bob, what’s a linear power supply in this context? A plug and play replacement for a wall wart?

I like to put wall warts outside of the audio power conditioners. 

I would use an extension, like a power strip from the conditioner, for the wall warts. (and I DO!) I use an old Adcom conditioner just for the WiFi and a powerstrip for my phone charger, the Laptop charger, a nearby lamp. I used to also have the wall wart for my Rega P5 turntable in it too. but recently moved that wart to a Furutech GTX duplex.      
Make an extension.. get a dual duplex box at Menards etc, stick in two duplex, wire it up. Plug it into the conditioner.
