Someone needs to machine a 2mm or so brass plate to fit underneath a p5 and report results. Guessing it would may have favorable sonic results similar to the P6.
Replace the tonearm screws with nut and bolt and other end bolted to the bearing bushing or whatever its called. Same priniple of stiffening/unify arm and bearing?
My understanding that's what the brace design is addressing.

If you can keep a secret, I've worked on something I'm currently testing on my P5... More later when I've compared among different carts.

My understanding is that they went cheap, and instead of continueing the "...complex CNC machined skeletal low mass micro-fibre plinth" from the P5, P7 and P9, they just use the glossy P3-24 plinth and put braces on it.... :wink:

BTW, this is the "...complex CNC machined skeletal low mass micro-fibre plinth" from the P5, P7 and P9" :mrgreen:

Seems like some rocket science being involved, eh?

Hmm, putting a metal hat on the standard sub-platter really looks like a halfway house measure to me. One step forward to put the fancy platter on, followed by two steps back with a badly designed sub to make it fit. Is this platter really that much better than the one it replaces?

Still, another product for GT- tall subplatters! :D

I don't feel so bad now looking at my old Linn Axis which is an MDF top separated by springs from an MDF lower wrapped by a wood perimter.

I'm glad you said it RoDa as it sure seems like they cheaped out.

Water- awaiting the scope and results of our experiment.

Radiance, where did you get that image? Something about the geometry of the plinth doesn't look right compared to my P5. The cutout for the motor housing appears offset too much from center, and doesn't align with what appear to be the bearing and arm post holes.

The P5 plinth also has some metal rods incorporated into the mdf, I learned from widening the arm post hole, so it's not simple mdf sheet with holes cut out.

But if the image is the real deal P9, then Rega clearly has a history of overstating the facts.

brianmch - more soon, I promise!

Watercourse, this is a picture of the Planar 9 plinth. In the left corner of the picture you can glimpse the Planar 9 wooden frame...

The P9 plinth won´t look so much different...

Since Rega has a new supplier for their TT plinths, Kelvin, being a kitchen manufacturer from Scotland, I´m pretty sure there are some manufacturing costs saved...

Wow, Rega seems to get a real beating in this thread. :wink:
And I appreciate it coming from Rega fans, then it's not just flaming.

Do you guys think they have started an decline, or has this always been the case?
Maybe they have always exaggerated the designs in order to make a few extra bucks (or simply to be able to cover expenses?).
I am sure all companies to this, the important thing is that is holds up to the claim.

And they do sound good, don't they?

A picture of the Planar 9 to laugh at Rega's statement about the P5, P7 and P9? [-X

Didn't think it was rocket science, but for shure more expensive than the P3 plinth to manufacture. :wink:

Groovetracer subplatter'n'platter will still fit.
You'll only need a taller subplatter if you want to keep the RP6 glass platter. :wink:

The Regas have earlier been the good arms with the cardboard plints, too poor data to be listed (wow'n'flutter) and the turntables for low budget systems.

The new models seem to be stretching the simplistic approach too far?
Most obvious on the RP6 replacing the P5.
The P5 had the RB700, same as the P7 and a different plinth than the P3.
The RP6 has the RB303, same as the RP3 and the plinth from the P3-24.

Dealers refusing to demo the RP3 vs RP6 with a TT-PSU on the RP3....
On the other hand, if the RP3 is as good as it seems, I know where I would go:
- Groovetracer system (subplatter, delrin platter and counterweight)
- TT-PSU
