I do not think there is a shop anywhere that demoes Tekton. From what I understand, it is a mail-order company with money-back guarantee of some sort.
Many audiophiles are happy to host other interested audiophiles (millercarbon certainly being a generous one) so you may try in your area. There are Tekton owners groups on the Internet, maybe someone on Audiogon will notice, etc. Ask and you will (probably) find. Of course, the question is do you want to do it right at this moment.
