Chazzbo,
I have not heard the Rogue or Cary amps. However, your choice in amplification will depend on the sound you wish to generate from the n803's. The Nautilus line,in my opinion, allows you to hear quite clearly what your upstream components sound like. These speakers play clear as a bell and are extremely neutral. Your electronics will dictate everything. Remember though, the n803's can handle very powerful passages with ease. But with a low power amp you may not have enough juice to get the full effect of this. My recommendation is to try to get an audition of the BAT vk 500 or possibly a Plinius sa-100 or 250. You'll be able to achieve power and depth and delicacy at the same time. By the way, I own the 801's. I hope this response was helpful.
