Record clamp


Hello Audiogon Forum,
I have a Rega P3 turntable with a Kiseki Purple Heart phono cartridge. I am wondering if utilizing a 5.4 ounce light weight record clamp will add to the sound quality at all or will a record clamp hurt the turntable in any way?
Thanks so much for your input.

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.

Rega table is a low mass but not suspended, so the clamp/light recommendations are spot on. You should get better performance than a heavy weight style, and certainly don’t want to use a heavy weight style on a suspended table (but better match with high mass tables)
.
My table was high mass- 25lbs just the platter alone - and the Gravity One easily had greater detail, dynamics, extension, and even bass than when records were clamped tight to the platter. Clearly there is a huge difference between sophisticated designs like the Gravity One and all the others which are basically clamp more and tighter.
 This makes a lot more sense if you study my threads on vibration control, my turntable, Townshend Pods and Podiums, etc. Then it becomes clear rigidly clamping can only take you so far. The greatest benefits by far are allowing the record to move, but in a carefully controlled manner, and dissipate energy as efficiently as possible, and as evenly across the whole range of frequency and dynamics as possible.  

This you cannot do by simply clamping and weighing it down. Not on any table. Of any mass. Or suspension. Or lack thereof.
If you want to improve sound quality, the Origin Live Gravity One record weight is the best I have heard, by far. It is also the lightest, and easiest to use. This record "weight" is only about 2oz. Unlike others that clamp or use mass to damp vibrations the Gravity One uses a combination of different materials. It looks and feels and works unlike any other.  

It contacts the record only on a small triangular shaped area near the spindle. The weight itself uses a flexible rubbery type spacer to avoid coupling to the spindle. It effectively channels vibrations generated in playing a record off the record and into the weight without reflecting any of this energy back into the record. Being decoupled from the bearing it is unable to channel any vibration from there into the record. It attenuates all frequencies evenly.  

The result is improvement in transient response, timbre, detail, and extension. Not subtle either. I was shocked how much better it works than my carbon fiber clamp, that was until now the best I had heard.  

I got this with my Origin Live Sovereign MkIV turntable. Tried it on my Teres before setting the Sovereign up. They also make a record mat that uses a similar approach and can be bought separately but on the Sovereign is bonded to the platter or I would have tried that on the Teres as well.  

The Gravity One is a total no-brainer. Record weights by the way, no they will not harm your turntable, platter, bearing, at all. If you are the least bit concerned however then this is by far the lightest one on the market. And most effective.
