I use the 700 series which replace the CDMA NT. Both use the Nautilus tweeter (NT). I also own 600 and 800 series and these are a sweet spot. Easy to drive like 600 series but much more refined.
You do not need a massive amp but a good 100 wpc integrated is ideal in my experience. My 50 wpc Linn and Rega integrated were fine but at low volume, I found my 100 wpc McIntosh or modern Yamaha integrateds were a lot better. A big NAD works well too. A nice tube amp will be a good choice too as long as it is not one of those really small one. A 75 wpc Cary or McIntosh is a good choice.
These are very high quality and revealing speaker so they will reward care in your set up. I use Transaprent audio cable as the little network boxes were very good at suppressing line noise which the NT are reproducing. I use some level of isolation on all components in the chain, even the amps. Again these speaker will allow you to hear the differences that small tweaks make. Enjoy.
