David I will start on Magus then the Mini floor standing.Yes I will let you know.Happy Thanksgiving belated and your family, my friend.
Bon, thanks!  Cool. Say Hi to Jon from me. Looking forward to hearing your take on the Magus and Nenuphar Mini speakers. Your amps will be a nice pairing!
At the risk of straying too far afield from the subject of this thread-- although really isn’t the subject the Nenuphar speakers and how to optimize them?--I want to report on an optimizer that’s a little further down the chain of the typical pairing of amps and/or pre amps. Just to remind folks I drive my N’s with the Vinnie Rossi L2i-SE (which bested by a surprising margin the LTA Ultralinear and First Watt SIT-3 and SIT-1 amps) and remain impressed if not overwhelmed by the synergy. (I see some folks here considering pre and amp combo’s that are about the price of the VR and would just say to put it on your radar.) In fact I was in that happy state of "it can’t get better than this" (a state where you should drop all your audiophile acquaintances and vendor relationships if you want to preserve it), when a friend brought over a power cable he said I had to hear. It was a Shunyata Omega QR 15 amp power cord as thick as a summer sausage. And it retails for $7.5K! This thing which is both a power conditioner and cable incorporating a bunch of technologies I thoroughly don’t understand, immediately raised the optimization bar of the Nenuphar’s by--I don’t know how to put it, a component, a mile, by more than anything except adding the VR? Even then I’m not sure, it was like adding another VR, just made everything BETTER BY A BUNCH. Bring out all the superlatives in the audiophile handbook (including where the bottom part of your face hits the floor) and add in something uncanny that had to do with speed and pace that focused my interest with a life like quality I’d never heard before. How good are the Nenuphar speakers? So good that changing that 6 feet of wire between your wall outlet and your amp could make them sound even bigger, more alive and life-like than you had heretofore thought possible. So far the Nenuphars have followed my dream and my pocket book as far as the two might take them.
Hi Stephen,
Thanks as always for providing your listening impressions and observations.  I've been involved in enough cable comparisons over the years and know without question the positive impact high quality cables can impart in an audio system. 

I acknowledge there are those who would write off what you've heard and refuse to believe that cables/conditioners  are capable of providing this degree of sonic impact. That's their problem, not yours. I have no doubt that your system is sounding simply marvelous. You continue to discover how exceptional the Nenuphars truly are.
