Good morning david_ten,
A party of one. The audiophile disease is a lonely pursuit. I have exactly three audio buddies in real life. The closest is about an hour and a half away. I try to turn people on to this stuff but few get it. It’s not that they don’t hear, it’s more that they don’t give themselves time to come under the spell properly. Also, people don’t know or have forgotten how to listen as the primary experience. And then there are those who are incredulous about the expense. "You mean you could have bought a boat instead of a stereo?" Some get it and want to get away from it as fast as they can so it doesn’t infect them becoming the expensive itch that must be scratched.
My wife used to hate it but is learning to appreciate it. Until just recently when she looked at it all she could see was dollar signs.
Dave Slagle and or Jeffery Jackson have a blog called HiFi heroin.
True enough.
I live just outside San Antonio Texas.
I actually have a new friend in Victoria who wants to come up.
He has friend in Houston that has a Kondo Kagura based system.
I hope to experience that someday. 


I have met a few local audiophiles through classified ads, and I did sell a pair of Triangle floorstanders to a neighbor. He drives them with his Sony receiver and is quite happy. He felt no need to upgrade anything else.
I would like to add my two cents to the discussion about amp compatibility, specifically regarding damping factor, with the Nenuphars.  To recap: I've had extended auditions with three amps: the LTA Ultralinear, The First Watt SIT-3 and the First Watt SIT-1.  I settled on the SIT-1 for its overall superiority--not just one thing it did better than the rest.  However, one area in which the SIT-1 excelled that I believe might be related to damping factor is scale.  As mrubey and others have commented, the Nenuphars are capable of creating the scale of much larger speakers.  But not only does the SIT-1 bring a noticeably increased sense of largeness through a sound stage that opens more in every direction, but it increases immediacy and involvement when playing at low volumes.  I found this to be even more important than increasing the largeness of scale since I'm an early riser and play at relatively low volumes for several hours before others wake.  Does this have something to do with damping factor?  I don't know, but Charles and some of the other more technically astute posters might.  Although all the amps I've mentioned have relatively low damping factors, the SIT-1's factor is 2 which is the lowest by a significant margin.
