Once the VTAF bushing is installed, an arm can be removed and restored in moments without breaking or making mechanical connections; and without getting underneath the turntable plinth. - Jeff Day
ACHIEVING the BEST VTA ADJUSTMENT RANGE:
The best approach to achieving the right VTA range is to do a simple installation of the VTAF™. Then, with the VTAF at its lowest setting, and the stylus in the groove of a standard LP record, check to see it the rear of the cartridge is a touch lower than level. If not, you may shim between the rear of the cartridge and the headshell with one of the precision shims included with the VTAF™. The precision shims are provided in thicknesses of .010", .020", .030", .040", and .050". Each shim has the same effect as lowering the tone arm pedestal about .10"
The VTAF™ has a vertical adjustment range of 7/8 inch. The typical record collection will require an adjustment range on the order of 1/4 inch. In the easiest of all outcomes, a simple installation of the VTAF™ with a Rega arm, with no shimming of turntable, tone arm, or cartridge, will be able to access the best sounding VTA for a wide range of records. If not, shimming as described immediately above will probably do the trick. There are several ways to achieve a lower value of initial VTA. Some turntables have adjustable armboard height. Some users may choose to change the thickness of the record mat as another way to achieve the right VTA range. Be aware, though, that changing the record mat may affect the sound of the system, possibly making it more or less desirable. Also, a user may choose to incorporate a wood spacer between the headshell and the cartridge to lower intitial VTA. Upon request, I will provide at no cost to the user of a VTA a lightweight wood spacer of user specified thickness.

Bass response and definition has improved immeasurably. I am astounded at how much difference this makes. - Dave Kell
