Just picked my "new" SDA-2Bs. I was very lucky. They came in the original boxes with all the packing material and are in near new condition. And of course they came with the interconnect cable. I even have the original manual, SDA brochure, and the original receipt.
I hooked them up to my Sony receiver just to do a quick check and they sound fantastic.
When my back is feeling better, I'm going to use them in my 2 channel Hafler system.
