I don't think that a constant roll-in of EQ would be helpful. On playback, the stylus is actually parallel to the groove at two positions, both in the middle of the disc, not at the edge, as depicted on a cartridge alignment protractor. https://www.audio-technica.com/en-us/support/audio-solutions-question-of-the-week-how-do-i-align-my-audio-technica-phono-cartridge/ https://www.audio-technica.com/en-us/support/audio-solutions... So you start playing a record and the stylus has a small lateral load bias to one side, has a zero crossing, an small opposite side bias, another zero crossing, and then finishes up with a high lateral load bias on the inner groove and all the female vocals sound terrible due to the extreme sibilance distortion.
