Record clamp

On MC’s recommendation, I’m trying the Origin One Gravity Record Weight on my highly modified Rega Planar RP3 turntable with a Clearaudio Virtuoso cartridge.
Initial testing shows slight but definite sonic improvement.
The overall sound is smoother yet more detailed with some improvement in sound staging. Not a night and day difference, but a nicer listening experience.

I doubt the record weight will harm your table. I cannot comment how if will affect your sound.

I suspect your sound is compromised by the very large quality/performance gap in turntable and cartridge choice. The record clamp will not remedy that. 

I'd advise you to pull the cart and keep it handy for when you upgrade your turntable. Rather than a clamp, invest in a cartridge with a performance more inline with that of the P3. Won't hurt to do both cart and clamp though. 

rvpiano, Good to hear. Glad it worked out for you. 

It will not hurt your TT. you might get some SQ out of it.
just be careful not to over clamp it where the album starts to warp. If you don’t like it put it away, maybe on another TT.
I have been using a clamp on my TT’s for 40+ years.
My Oracle Delphi came with a clamp. My present TT Clear Audio Master Solution, I use a CA clamp.
Try different types of devices. Respectfully

Another good one to try is OL Cartridge Enabler. While I hate the name the darn thing seems to work at least as good as and probably better than fO.q tape. The Enabler is made from some material he developed. It looks sort of like felt but clearly not, it is directional and even labeled so one side goes against the cartridge the other against the head shell. There are also washers made of the same material. The deal is you have the bolt, normal washer, Enabler washer, head shell, Enabler, cartridge. So the cartridge is effectively isolated from the head shell by the Enabler material.

The material is kind of squishy. After a while I was playing around and found the sound can be subtly tailored by slightly tweaking the torque. Like a small fraction of a turn. Does not like to be real tight.
