Speakers Nominal Power handling/Amplifier

My Canton k9  bookshelf speakers have a nominal power handling of 120/200 watts,  SPL of 87db my Technic integrated amp SU-G700 has 70 watts into 8 ohms,140 into 4 ohms.  As an aside, my source is a Marantzcd6006  CD player.
What does Nominal power mean for me in terms of music reproduction in my system? Specifically Will the speakers perform to there potential with my 70 watt amp? I read that nominal power relates to the power your amp should have to drive these speakers. So what am I missing with only 70 watts per channel besides playing louder? what would an amp with 120 to 200 watts give  the speakers that would improve the music? Am I placing my speakers at risk using less power then what the speakers can handle?
I'm a rookie with zip, zero, nada, listening experience to fall back on that is at all relevant so take this with a grain of salt I freakin love the sound detailed(decay of strings and brushes on symbols, fingers plucking guitar strings etc) soundstage( speakers vanish instruments are here there everywhere but not outside of speaker footprint and not real deep front to back )imaging ( instruments have there own place voices are in the center) not harsh or bright but detailed not warm sounding. How much better could it get with a more powerful amp? I can only imagine what a high-end system must sound like!
An observation no audio stores are within 50 miles, unless I count BestBuy so I sadly I must rely on reviews for the most part and what I read here. Regards Scott

Preamp out to subwoofer. HPF and LPF would depend on the individual subwoofer, no?

Adding subwoofers is a work-a-round for the OP since he is married to this amp and speakers.

The integrated amp has a   "pre out right and left"   it say in it's manual for hooking up a subwoofer however it does not mention the word high pass filter. 
 The Jamo c80 is a powered sub and has 1800 watts. It has the word  "Line"   and beneath the word "Line", it has  four  for lack of a better word interconnect attachments (you know a gold outside cover, white plastic interior and a hole in the center)one is marked  "Left/LFE"  next to it is a similar input marked "Right In". Directly below those two are two similar looking outputs marked "Left" and "Right Out".
  • So can my integrated amp and the sub be connected in a way to relieve the Cantons of their bass responsibilities? 
  • If I can what should I ask for to connect the two channels?
  • I know I'm sounding like a 74 yr old grade schooler but hey you got to start someplace.
Thanks for you help.

LFE is for use with a multichannel receiver. You would use a RCA cable from preamp out to RCA LEFT, RIGHT IN on the sub. 
If no high pass filter on sub, only low frequencies will be used from the preamp. 

Check the sub for high Pass, low pass settings.
