Sheffield -A2TB Test Disc ‘My Disc’

The Sheffield Lab Test Disc is one of the most respected audiophile test and demonstration records ever produced. Released by Sheffield Lab, a legendary American audiophile label, it was specifically designed to evaluate and fine-tune high-fidelity audio systems with exceptional precision. Unlike ordinary test records, the Sheffield Lab Test Disc combines both technical test signals and high-quality musical recordings, allowing listeners to assess objective performance as well as subjective musical realism. Sheffield Lab was famous for its direct-to-disc recording process, which eliminated tape and preserved maximum detail, dynamics, and transparency.
