(27db) to "poor" (16.5db) at lkc. These flgures reveal that there is

very little consistency in performance characteristics of the irnita-

tion Dynetic Styli.

In each of the categories shown above, the results ranged from

good to poor. As a matter of fact, only 10% of the samples met the
Shure performance standards for the Shure N3D Stereo
Stylus. In adoItion to our test findings, our Service Department
records show that an increasing number of
tridges are being returned because of poor performance-and our
examination has disclosed that most of these returned cartridges

are using imitation Dvnetic Stvli.
CONCLUSION: Obviously, if

we cannot guarantee that the performance of Shure
cartridges will meet the published Shure
substitute.
