Upgrading from Rega P5 TT


Looking to upgrade from a Rega P5.
Does it make sense to go from the P5 to the new P6.
Is this a latteral move?
Or do I have to go up the ladder to the P9 for better performance?

Damn! I can't believe that Rega is dropping the P9 too!

I see that Music Direct also has a demo P7 for sale at $1649 here. It looks like they also still have a B stock model for $1795 here and here.

I didn't see any P9's though.

I have the GT Subplatter, counterweight
power supply
GCPH phono
10x5 Dynavector cart.

Maybe I should upgrade my cart, budget would be $800-1200
or
sell the P5 and pop for the P7.

I want to thank everyone for their input.
Get away from Rega while you can. By the time you do all the upgrades (I've been there) you could have a new Well Tempered Simplex. I have an Amadeus and I hear the Simplex is almost as good. The Rega is not in the same universe, even with all the upgrades.
The P5 would be a lateral move, as others have said. Also, many people do not consider the P7 enough of an upgrade over the P5 to justify the price increase. Most say you need to step up to the P9 to significantly upgrade.
