Rolls Bellari VP549 Phono Preamplifier
The RIAA equalization curve was intended to operate as the global industry standard for records since 1954. However, it is almost impossible to say when the change actually took place.
Reducing the low frequencies also limits the excursions the cutter needs to make when cutting a groove. Groove width is thus reduced, allowing more grooves to fit into a given surface area
This also reduces physical stress on the stylus which might otherwise cause distortion or groove damage during playback
