I assume you are now asking about adding a power amp Brad. Much more information would be needed in order to answer your question rather than make any kind of blanket statement. Would need to know the make and model of your speakers along with sensitibity and mpedence. Also, how big is your room and how loud do you like to listen? Depending on these answers, you may or may not see any improvement in adding a power amp.
At least you have an answer to your original question about acquiring a P7. You now understand that you don't need one because you already have a fine AVR in your Pioneer VSX-53. Best of luck in your audio journey and Happy New Year!
