Many thanks for your post and I'm in the process of redoing the line. The super 3s are available and the Grande 6s will be available for a while longer.
Great to hear about your new amp. 1 watt is really tough and they only feedback that I have regarding very low power is the Berning ZOTL. This amp is 1 watt and I have been told the Grande 6s work. How loud, I really don't know.
