@info...if you prefer the sound of a ceramic cartridge on a console hi-fi, it's hi-fi, not the source. That ceramic cartridge has a frequency respnse of about 100 to 7.5khz...that's it. The same as most AM radios. The magnetic is 30 to 17khz, wider than FM. It WILL reproduce all the grit and clipping in a worn record. And if you've been playing 45's on a 5 gram weight tone arm, they're toast. The "diamond" (man-made) on that ceramic cart is massive, and conical, compared to the fraction sized, elliptical one in the magnetic, tracking at 2 grams.
Another possiblity, the 8uf capacitors used for the crossover to the tweeters in the hi-fi have dried out, and thy're rolling off at 7khz, taking all the harsh clipping out. And that's why you like the sound.
Basically, you'd get the exact same results, without further 45 wear, by playing with the magnetic cart, turning up the bass and killing the treble! Also, if your receiver/amp has a mono/stereo switch, and the 45's are mono, throw it in mono to reduce the lateral clipping by half. Also, be SURE your tracking weight is high enough. Magnetic carts sound dreadful when they are misadjusted too light. Don't guess, find out the factory reccomended tracking weight range for that one, and set it in the middle. (1.5 to 2.5g...set it for 2 to start) Lighter is NOT necessarily better. You choice of Magnetic cart is a good one IF the stylus is good.
