Hello,
I recently built a preamp to increase the amplitude of a turntable output before feeding it into an AUX input of a cd player. It works pretty good , but I guess it emphasizes the higher audio frequencies because it exaggerates the hiss and *****le and every imperfection of the grooves in the records. Some records sound good and others don't. If I put a low pass active filter before the preamp, on the output of the turntable, with a cutoff frequency of about 15KHz and a steep enough rolloff, would that help? Or should I try some other cutoff frequency, or some other method?
