Yea, sorry about that Julius Peppers thing...
The tach by itself would not provide any real sonic benefit other than ensuring the platter is at the right speed. It performs the same basic function as the KAB strobe, but much more accurately and with a direct read out rather than just fast/slow. At the edge of a 12" platter, a 0.01 RPM error translates to a recession or precession of ~0.006" per rev (about the thickness of card stock paper). It is very difficult to see this with the naked eye unless you track it over a longer period of time. The RoadRunner produces its 1st reading after 2 revs and updates every rev afterwards.
The Falcon PSU provides a stable clean AC source for the motor that in most cases will improve the sound. The problem I found was no matter how accurate and adjustable the power supply, the speed on belt drive tables are prone to drift over time. The speed is also extremely sensitive to belt tension, position on the pulley and other variables that are difficult to control. By connecting the tach output to the Falcon PSU, the speed is not only stable and clean, but remains accurate no matter what external variables try to influence it.
