Need help choosing speakers to replace my B&W 606s

I currently have a 5.2 system that I mainly use as a home theater. I have a Yamaha RX-A1080 receiver, the B&W speakers with a center, and two SVS-2000 subs. I am looking to replace my 606s with something more impressive; more soundstage and clarity. I want to keep using my receiver; hence, I don't want something that is difficult to drive. My room size is 12' x 13'. lastly, my budget is up to $1500 but I am willing to build my own cabinets so I am mainly looking for kits at the moment. 

These are the speaker kits that I am choosing from at the moment:

• Philharmonic Audio BMR
• https://meniscusaudio.com/product/philharmonic-audio-bmr-speaker-kit/
  
• Statements II
• https://meniscusaudio.com/product/statements-ii-full-kit-pair/
  
• Satori Ara 2 Be
• https://www.madisoundspeakerstore.com/speaker-kits/satori-ara-2-way-speaker-kit-pair/
  
• Audio Nirvana Super 10 ALNICO
• https://www.commonsenseaudio.com/drivers.html
  
• Lii Audio Silver-10
• https://www.lii-audio.com/product/one-pair-flagship-10-fullrange-drivers-new-development-for-better-detail-balance-silver-10/
  

Right now I am leaning towards full range drivers because of the convenience, but I can't convince myself. Would appreciate some advice and suggestions. Thanks.
