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.
