GRAVITY
Mitsubishi made some vertical TTs back in the 80's, but the tonearm hung down, not up, and it was a linear tracker.
This has fail written all over it!
I had a short listen on the GS-XmkII. Initial impressions were very good, and I'm not an HE fanboy in general.
Would want more time, but the HE1000/GS-XmkII combo is a winning pair IMO.
