All tables you mentioned are top tables, the Basis being the one I would consider the least desirable sonically. You should also look into the new Grand Prix Audio Monaco table. I previously owned the the Basis Debut Gold, SME 20/2, and now have the Grand Prix Monaco. It looks simple, but is very innovative and brilliantly engineered. It is a direct drive that is done right. I did not hear the drawback of belt driven tables until I compared it to a state of the art direct drive with the best speed accuracy available. The improvement is not subtle. Vinyl sounds AMAZING on the Grand Prix / Dynavector 507II / XV1S front end. The level of purity, resolution, transparency, 3D spacious layered image, focus, dynamics, presence, separation and quiet is incredible. Everyone who has heard this front end has had the same amazed reaction. It is something very special.
