Assuming your TT doesn't rumble, WOW, has no noisy cables, and connectors grounding problems, and has a quite motor runs on speed. a healthy oiled tone arm with tracking force adjustment etc or none of that all;.A stylus and cart are 99% of the sound experience assuming you got a decent phono stage amp, or a shitty one! Everybody suggesting otherwise are just rolling you! The cart and stylus ARE THE SOUND. Your TT and arm just shouldn't interfere with the sound path, that's all.! Every Hi FI TT from 1975 and onwards should be good enough ghat only cart and stylus choice should provide the sound difference / output to phono amp!
When the Linn Axis turntable came out in 1987, dealers were able to set up comparative auditions so you could hear the sound quality difference between the LP12 and the Axis even though both were fitted with identical arms and cartridges. You could also hear how much better that same cartridge sounded on the LP12 when you switched from the Linn Basik arm to the Ittok arm. A few years before the Axis came out, I auditioned, scrimped and saved, then finally purchased an LP12 with Basik arm because, by audition, I could hear that that combination with a cheap conical cartridge sounded better than my Thorens TD146 no matter how expensive a cartridge I asked the dealer to mount up for comparison. Later, when I wanted an upgrade, I first bought the Ittok arm, not more expensive cartridges.
More recently, Herb Reichert reviewed a number of budget cartridges (Stereophile's Gramophone Dreams #44). He had his own 1984 LP12 with Basik LVX arm and AT95E cartridge, a Dr. Feickert Blackbird with Schick tonearm in for review, plus a Technics SL-1200 MK2 he had purchased, and review experience with a Pioneer PLX-1000. While he's had high praise for both the SL-1200 and the PLX-1000, they couldn't match the more expensive turntables, "On the Linn LP12 and the Dr. Feickert Blackbird, the Audio-Technica AT95 sounded dramatically more controlled and powerful, more nuanced and sophisticated." Using the Dr. Feickert for much of his cartridge survey, he wrote, "On the Blackbird-Schick deck, these so-called entry-level cartridges played recordings with a layered, three-dimensional complexity that I thought was impossible at these price points. Quiet musical passages were not only quieter; they were filled with magic little details that got noised over, dulled over, or disappeared entirely on the Pioneer and Technics 'tables."
This doesn't mean a person needs a super-expensive turntable to enjoy records. Reichert enthusiastically recommends the PLX-1000 fitted with an AT-VM95C as a great way to enjoy records. I replaced my aging LP12 with a Rega RP3 and was perfectly happy. After losing all my gear and records in a cross-country move to another state, I spent the next three years with an AT-LP60X plugged into a Bose Wave radio, and still enjoyed the bargain-bin records I started buying at Half Price Books. But I also know from experience that better turntables and tonearms can extract better performance from a cartridge.
