Dave,
Sorry if my last post was confusing. Hopefully this will clarify. It has been my observation for the turntable brands I listed, that an owner is highly likely to stay within the brand if they decide to upgrade. For example, I know a new Galibier Serac owner who plans to upgrade to the Gavia platter. I have observed the same phenomena for TW Acustic and Teres.
I think that this happens, because the turntable brands are uniformly excellent, owners like the particular house sound of 'their' turntable, and the trade up policies are generous for all. Importantly for a handmade item, I also feel comfortable recommending the people behind all three brands.
BTW, I bought a Stelvio with Triplanar and Dynavector XV1-S and could not be happier.
Regards,
