Newport Test Labs’s testing proved that the accuracy of the AT-LP120XUSB turntable’s platter rotation was exact. A 33.33 rpm test LP with a 3kHz test tone recorded on it was replayed at exactly 3kHz. The speed stability through a full revolution of the platter was equally perfect, as you can see from the histogram (Graph 2) accompanying this review.
Rotational stability, as measured by Newport Test Labs, and as graphed in Graph 3, was also excellent. This test measures the speed for a full
