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.

Probably not the direction you’re thinking of but you already have a nice system. Maybe look at dedicated circuits and get some Hubbell Porter Port Outlets sold here, some aftermarket Pangea Power Cords if you’re using the stock cords then if you have anything left, go to the Bluesound website, go to shop/outlet and buy a refurbished Node 2 for $299 with a subscription to Tidal/hifi and enjoy new music.
