I'm currently using a Sansui FR-1080 turntable with an Ortofon stylus. It used to be my Dads. It's probably 40+ years old but still works. I replaced the belt several years ago and oil where needed. It sounds good for what it is a budget turntable years and years ago. It's dialed in and works but it has a motor vibration I can't get rid of. The platter is aluminum and spins well, the plinth is a metal plate suspended on springs sitting on a wooden chassis. The motor is an open frame AC motor suspended on 3 large rubber pads spinning a brass pulley. Two speeds 45/33 depending on which diameter pulley the belt rides on. Playing records the woofers would wobble once the needle drops. Wobble on silence and it looks to be motor related.
Looking for a good sub $500 replacement. Hi-Fi on an Lo-Fi budget. Some ideas are, Audio Technica AT-120, Denon DP-300, Music Hall mmf 2.2, Project Debut and ortofon Red. Or go used VPI, clearaudio, etc very rare to find them below $500. I've been reading lots of good content but mostly on other topics.
Opinions on the subject are fine. Maybe it's the way turntables are? I have no other experience with different brands. Would a record clamp fix it?
Speakers are Polk Audio LSi25
Amplifier is a Denon AVR-4802R in pure direct
