Very few arms have no VTA adjustment, in fact, the only ones I can think of are Rega, as they are not into fiddling about. Their argument is that it is far more important to have a rigid structure than to have a VTA adjustment. The Ittok has a VTA adjustment.

VTA varies with the cartridge, tracking weight, temperature, record cut and record thickness, so you need to adjust it every time you play a record. Fortunately, very few enthusiasts are that anal and an approximate setting is perfectly OK for most people.

IMO is nowhere near as important as the overhang, which really needs to be spot on or else mistracking will rear it's very apparent and ugly head for sure.
