I think I will try Ed Frias' design. It seems simple, the parts are
available in a kit, and there is a lot of support on audioreview.com
for help building and tweaking the speakers. Ed also seems to be a
very nice and knowledgeable person who is willing to help. He
suggested to me that I find a good amp and preamp instead of a
receiver. I have never considered that before, but I may be on another
learning quest to find out! I'd be happy with used equipment if I can
find something of quality for a good price. Back to eBay! ;-)
