Easy, If you don't like rumble get a P10. Idler wheel drives were the necessity of the day. They needed torque so the radio stations could cue up records and they needed to be able to change between three speeds quickly. Electronic control of motors had yet to be developed. Bass below 50 Hz did not matter as it was not broadcast and very few systems could reproduce it. Direct Drive tables put the old idled wheel tables out to pasture. Then they started show up super cheap on the use market and audiophiles on a budget bought them in droves, started hopping them up and deluding themselves into thinking they sounded better than modern turntables. They are very cool and in many instances much sturdier than some modern tables. But, they can not get away from the fact that there are too many moving parts and moving parts make noise regardless of how well they are made. At the speeds these bearings run at the resultant noise is rumble. Anyone with a good subwoofer system powering their room at close to realistic levels will not be able to tolerate this. If you think you can your subwoofer system is not functioning well.
If you were to build a new idled wheel turntable to aerospace standards it still would not be able to perform as well as a modern belt drive. It might come close when it is brand new but it will not last long as the idler wheel wears.
If you want to get an idler wheel table as a conversation piece, wonderful.
Otherwise stick to the modern table. The P10 is a great table but for almost the same money I would get a SOTA Sapphire with an Origin Live arm on it. Isolated tables rule.
