New Rega Planar 6

You might want to check this thread at a Rega owners site: discussion of build quality and plinth 'sagging':
Rega Planar 6 plinth sagging
I'm a longtime Rega owner, fwiw.

Thanks. Very Interesting.  This problem has not occurred with my Planar 6.  Fortunately, Rega turntables come with a lifetime warranty against manufacturing defects, as you my know, so hopefully the guy who encountered the sagging problem was able to get it fixed. 

Responding to the earlier posting on this board by Mofimadness, I agree with what you told Roy Gandy.  To compound the confusion, the new Planar 6 has “P6” on the plinth and the cover of the manual, even though the P6 (or RP6) is the older model it replaces.  When I saw this, I was concerned at first that I had been given the old model (but it’s all good).

Hmmm...folks here have also called the RP8 out for sagging, so this very well may represent a design defect ala this foam material core. While it certainly expresses Rega’s philosophy of low-mass, I personally hold concerns about this material over the long-term.

Considering a new table, and both the RP8 and Technics SL1200GR have my attention, along with one or two others. But the foam core comes off as strange to me. Still, the table’s been in production for several years, and based on not hearing about it en masse, perhaps the issues have been fewer in number?
