@bfoura, I have used the 1200G with Timestep mod and tried couple of tonearms on them too. I used it along side a Loricraft Garrard 301, Jean Nantais Reference Lenco Mk2 (still use it) & SP10 Mk2. Everything in the same room, same system. I particularly dislike SMPS & Wallwart PSUs so I had the Timestep motor controller. The 1200G is a fantastic TT if you don't hear it's flaws. It sounds clean, times very well, no-nonsense.
But having other TTs in the room and being accustomed to idlers and BDs I heard 2 distinct drawbacks:
1. The note to note transition was not fluid, a start-stop feel.
2. Dynamics: Everything sounded smaller and controlled in 1200G compared to the other TTs. The explosive dynamics were missing. The SP10mk2 was better. The idlers were simply in a different league. My previous TT was a Platine Verdier and that too had an effortless seemingly unlimited dynamics. 1200G sounds puny compared to them. If that's your concern then no tonearm or cart upgrade will cure it.
But 1200G still has its pluses. I have not heard the SOTA but reading about it I do get a feeling it would be nice. Nottingham Analogue Hyperspace is also a good choice.
