There was internal damage and a cartridge floating around the box without it's protector over the stylus in my original order. There was no damage on the outside of the packaging so it felth like this was an opened box issue. One of the cartridges produced sound on one channel only. I requested an RMA and got a replacement from Thomann.
Have exactly the same problem with one of the 2 cartridges (though no damage. Mono sound only. I mad sure I did my tests as I couldn't believe it would happen 2 times in a row. Known good cartridge produces stereo, the other one produce only one channel same vinyl. Tested other turntable - same thing. Either someone in Thomann's warehouse is messing about, or they have extremely poor quality control on this product, or both.
I definitely won't buy this again. Lost some fate in Thomann too.
