Weight, Clamp or stabilizer?


I have a vintage Pioneer PL-560 Direct-Drive Automatic Turntable purchased around 1980.

I'm trying to get it to produce the best sound its capable of.  I plan to order a set of SVS subwoofer feet to replace the worn feet (I have an SVS subwoofer and removed its feet and temporarily placed them on the TT base with good results).  I read an article about TT tweaks.  A few things they suggested were an upgraded mat, clamp and isolation feet.  Thing is since the TT is a direct drive I don't know how much extra weight it can take (if any), and the spindle is about 7/8 inches tall so I don't know if that's enough for a clamp.  The original rubber mat it came with is in great shape. Do I need to replace it, too? I'm willing to invest in tweaks to improve this turntable, but not interested in replacing it.

@hifigem, that $1K periphery outer ring clamp is way out of my budget. I can be happy hearing what my modest setup has to offer without it. But for those who can afford it, I'm sure they'll be happy you shared the info.

Got it, thanks. I copied your name as well as text, so others would know who I was responding to.

I didn't get a notification that you had responded to me. Is that possible here?

I have the Shure m97xe high-performance magnetic phono cartridge. The arm is the original arm. I found instructions for cartridge and my specific turntable's arm setup online in the operating instruction manual, rare and detailed.

I also use M97xe. Love it, actually prefer it to my two Microline's (shure and audio technica).

Shure just stopped making stylus, the prices have tripled in a short time, keep your eye out for a replacement stylus at some kind of price.

I've had some fancy tt in my time, prior favorite was Thorens with SME arm, but my floors are too springy, it's bearing not good with vertical movement. I am quite happy with my current Audio Technica LP120 so I know what type of arm you have as well.

Often, finer engineering, i.e. 7 pound platter, involves the avoidance of potential problems, not apparent improvements in it's fundamental purpose.
