Rega -Deep Groove Replacement Subplatter

There's a couple of reviews on audioasylum.

I started a similar thread on another audio board with regard to my P3 and the concensus was that the P3 is engineered to a price point, and the table is difficult to substantially improve without investing money sufficient to have just bought a new table.

My main problem with the P3 is speed stability. Apparently the best way to improve that is to have a new pulley manufactured that can accomodate two belts and forego 45rpm playback. Such a pulley is not commercially available so you'll need a friend in the machining business.

The arm is a different matter.

Hi Stefan,
I wasn't referring to speed problems in terms of absolute speed, but rather wow. I think the Regas have a wow problem and the only way to solve it may be to go to a more expensive deck with either a better motor controller, or higher mass platter, or both.
I'm due for an oil change, so I'll try the mobil oil. Is it the synthetic or normal oil they recommend ?
