Hi Ziva,
I actually own a Studio, and use it as a backup turntable (my main table is a Verdier). First, for a used Studio, 3500 Euros is overpriced - many other used turntables would be preferable, including VPI Aries, Townsend Rock Reference - heck, you could probably get a Verdier Platine for that much. Also, the Goldmund T3 tonearm is really problematic, fussy, and not pleasant to optimize - I wouldn't recommend it to anyone at this point, given the lack of parts availability.
