Peter,
I would shoot Audio magic an email. Jerry has usually been pretty fast in getting back to me. I got my nanoplexes straight from Jerry. He ran an add for them a while back and sold them direct. Another option would be to contact Audiogon user Fork, who is an Audio Magic dealer. As I said I was not expecting much, but I was just stunned. One thing I would mention is that they sounded great straight out of the box, but after a few hours they went through a period of a few hours where my amps didn't sound so good. I left them on for a while, maybe a couple days, and that seemed to do the trick and they were back to sounding super again.
If you look at my system page you will see I am using other Audio Magic gear for power treatment. It seems to really be working well for me.
