While these (and perhaps others) may be made in the same factory, I don't see how they could be "technically the same". Some of these turntables have "S' shaped tonearms while another has a strait tonearm. One is fully auto, another is manual and a third is a manual turntable with auto stop. One has a motor set off from the platter and others don't. They come with different cartridges.
The Music Hall and Pro-Ject TT's are also made in the same factory. They are not identical but more similar to one another (or at least they were a generation or two ago) than the three said to be made in the same Chinese factory.
