another rookie question - preamp or or power amp


I have a decent integrated amp ("decent" - to my ears). SS, 50Watts to 8 Ohms. It  has a preamp output. 

I have been looking at used power amps and preamps in the 2-400 dollar range.  

For example: the Parasound 2125 power amp, the Parasound P3

This is an OR question. Which choice will yield a better improvement,

1) if I put a preamp before my integrated so the integrated acts as the power amp

or 2) if I use my integrated as a preamp to a power amp?

It's also a choice to sell my integrated and save up until I can buy both a power amp and a preamp, but obviously I am itching to try one of the above options. 

My room is 15x13 so I am not sure I need a big power amp (big: 100Watts?)

Get both when you can ....from the same manufacturer....they will have been designed to work well together

You dont mention your speakers then it is difficult to recommend an amplifier ...

By curiosity which are they ? 😊 Efficient one or not ?

Unlike many people i had reduce the size of my room and speakers and i had never been so happy , even if my soundstage is not as spectacular as in my past acoustic room this is satisfying and surprizingly clearer because my past speakers were old and i listened now in near listening field ...The small  active  modified speakers i own had other qualities compared to my past speakers...

Then downgrading is not necessarily loosing on all counts ...
