Need advice on what to look for in a turntable - budget $6K to $10K

Mmporsche, Brinkmann will cost more than you are planning to spend. I also suspect that it is in a totally different league. If you are ready for that you are ready to audition it.
Though I didn’t hear the Parasound phono stage, I never heard of anything world class for this kind of money, not even a single cable.
It also depends on the cartridge. Assuming adequate prices, phono stage should be two/three times more expensive than cartridge, in my opinion. It is a very important link, aren’t they all? Besides, you might want to have a tube phono stage or at least compare tube and solid state. That mid-level transistor phono might destroy your sound.

Why not a T-W Acustic GT ? Whose who bought it think it is a very good value by itself and for the price. With a good arm I rhink it drops in your budget.

I think the TW Acustic GT may be north of 10K. The Brinkmann Spyder is a nice table…. I heard it last year, with a Reed arm. But definitely north of 10K. Pear Audio and Kuzma have offerings within OP's stated $ range. The Raven 1 with an Ortofon arm may be within budget….. 

Three I think you should check in that price range are:

Garrard 301/401 with Woodsong Audio plinth and Ortofon or Jelco 12 inch arm

SME 15 (can include a SME tonearm)

AMG Giro (this includes a great tonearm from AMG)

I would not be able to go past the new Technics 1200G.  Torque to die for, iconic looks (if that matters) and not to difficult to put on an aftermarket arm if you sooner or later want to upgrade.
