looking for thoughts on an amp

Current system is a rega mira 2000, rega apolo, totem sttaf speakers, connected with pnf cables. Looking to replace the mira. Here's a list of what I'm considering at the moment. Rogue Audio Cronos Magnum or tempest 3, Rega Elicit, Blue Circle GDC, Unison Secondo or Primo. Any thoughts on any of these from previous owners, thoughts on fits within my system and consequences would be appriciated.
