Building a mid(-upper) range stereo with Marantz and Klipsch

Have a nice day !

I am new to this forum. I am no expert. I am about to build a stereo system so that I could listen to hi-res 
music and the (flac) rips of my cd collection (classical, jazz, popular…).

*I have purchased lately a Marantz NA6006 network player.
*I have a pair of Klipsch RP8000F floorstanding loudspeakers.
 ( at the present time they are connected to an almost 30 years old Yamaha AX570 )
*After reading a lot of info I came to the conclusion that the Marantz PM8006 amplifier is one that is worth 
 to buy.

Or instead...

*I also thought of connecting the NA6006 to a MM7025 power amplifier through the variable rca out of 
 the NA6006 and drive the loudspeakers this way.

My questions are:

1./ does the PM8006 have enough power to drive the Klipsch RP8000F without causing harm to the
     loudspeakers ?
    ( for me it is a plus that I can connect an active subwoofer to the PM8006 pre out )
2./ is it a good idea to rather buy a MM7025, connect it to the NA6006 variable rca out and thus have twice 
     the power to drive the RP8000F ?
     In this case would I have the same or similar quality stereo experience as with the PM8006 ?
     In this setup is it possible to connect an active subwoofer the fix rca out of the NA6006 ?
3./ Am I right to suppose that I could connect the NA6006 to the PM8006's network input then plug the
    MM7025 power amp to the PM8006 pre out, thus being able to work with 140 W instead of 70 W, what is
    maybe better for the 150 W (cont.) Klipsch RP8000F ?
    If it is technically viable would this setup sound like a hifi at this price should ?
    Also,  In this setup is it possible to connect an active subwoofer the fix rca out of the NA6006 ?
   ( though the price of the PM8006 and MM7025 together starts to quite stretch my budget )
  
   
Please help me to decide what is the better solution.
Sorry for being so long.
Thank You.
