new equipment power conditioner or more powerful amp?


I have around 1-2 grand to use for my stereo. I live in an old 1960 house. I can purchase a more powerful
integrated such as the Rogue Pharaoh, or 'a conditoner like PS audio power plant (used). 
My system has a Rogue Sphinx, apollo cd, Aurum Cantas V3M, with good quality cables. 
My room is 11' by 12'  8' high. 
Thanks for your thoughts.

I agree with those that suggest one or two dedicated AC lines along with some of the many good quality duplex outlets, assuming you don't already have them in use. 
One more thought, if you are interested in adding power conditing to your system you might consider the Equi=Core 1800/Core Power Technologies which is balanced power. Walter of https://www.underwoodhifi.com has purchased the rights to this product and I received a sales flyer saying that he has five of these units available at a sale price of $1399 I believe. I've owned this product for several years (since its development) and for the price I recommend it.
