Of greater concern is the fact that much above 2‐3V out put at 20kHz and above,op-amp distortion starts to increase dramatically if called upon to drive heavy loads6. There’s not much music energy above about 5kHz, but on an LP, there are the inevitable click’s and pop’s due to surface noise with high energy content that can range into the many 10’sof kHz. You don’t want these types of signals generating harmonics and causing problems with the sonics lower down in the audio band.
