but this stuff haven't the same quality... we can call that "imitations"?
It has the same quality, the print circuit board, faders, tonearm etc they are all the same. The only thing an "manufacturer" (because AM-Audio, Reloop, Synq and all the others aren't realy the manufacturers of these turntables and cd players) can change are the color, the logo and the options like an line output like synq has, the key correction like the Stanton ST-150. All the extra's are options (opt-in), it's all notified in the list i have from the original manufacturer in China.
When let's say AM-Audio orders the turntables at the original manufacturer the only thing they have to do is fill in an list with the opt-in items they want to have, send logo and color information and the container can be shipped within six weeks from china to europe.
