I decided on this Audio Technica Stylus to replace my Pioneer PZP1004 Stylus on Pioneer PL990 deck. They are compatible. I didn't want to buy one of the cheaper, readily available, brightly coloured replacements in case they were of lower quality & potentially damaging to my vinyl. This stylus was simple to fit and I'm quite impressed with the sound quality. Tracks well & nice clear signal through both channels. All good so far.
