The greater reflectivity of the Sheffield High Density Gold disc allows for a stronger signal reflected from the disc into your CD player's optical pickup.   This improves the optical signal to noise ratio, resulting in a greater integrity of recovered data and reduced jitter.   The improvement is easy to see with your eyes.   Hold a High Density Gold disc to a light and look through an unlabeled area of the disc.   The High Density Gold disc is noticeably more opaque than other gold discs.

The discs are coated with a layer of ultra stable premium lacquer, which provides excellent abrasion resistance.   The 24k gold used in the manufacture of High Density Gold discs is the highest purity available (99.999%).   This 5-nines gold achieves incredible long term environmental stability, so your investment in Sheffield Lab music will last a lifetime.   See, hear and feel the Sheffield High Density Gold difference!
