Little to question here. Probably made in China. If so.
What can happen is a production line is set up for a company (probably Wilson)…. the contract manufacturer produce the run for Wilson… a thousand.. The parts are shipped to the US and the production line continues to turn out parts… to be sold to any interested party.
In this case, if real, Wilson may have designed the piece and gotten their production run without being careful to make sure they protected their design and the finished pieces were sold to Dayton Audio (quite possibly with cheaper parts… so performance will not match Wilson’s).
Alternatively a Chinese parts distributor or contract manufacturers can offer designs with options (custom labeling and/or different quality sub components) if you purchase your materials / labor from them. Wilson could have told them what they wanted and the CM then gave them subcomponent options and labeling options, then produced this for them.
I have worked in China and Japan for decades with some of the largest high tech manufacturers. I have been involved in the manufacturing chain of all the portable and automotive electronics you all use every day.
One thing to be aware of… the internal components may be different… although the plate and connectors look the same. A lot of high end audio is the quality of the components. Or of course they could be the same… can’t tell from the faceplate.
