Upgrading from Rega P5 TT

I don't think the P6 is an upgrade over the P5, not much of one, if any at all. It's a shame you weren't looking a couple of months back, when dealers were closing out the P7 line for around $1800 brand new. That was a nice step up over the P5 at a great price, but as far as I can tell, they are all sold now.
That leaves you with a P8 ($3000-$4000) or a P9 at $5000.

If you want a P7 there is a dealer in Colorado that has a demo listed at 1795.oo
here is the link

I am not a dealer just have done business here and have been very impressed with the owners TT knowledge.

Otherwise I would jump from a P5 to a P9 MusicDirect is closing them out at 4K

Trip,

I think it really depends on how much of jump you want in performance. I do feel that the RP6 is a very, very good table at is price point. And you most likely would see some improvement. But, if you are looking for a significant jump in performance level, then your best bet may to be to look at the new RP8, or find a good deal on one of the remaining P9's that are around.

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.
