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

Transfi Salvation or PTP Audio.  The latter is an idler drive based on a Lenco drive system.  The former comes with a floating tangential tonearm and is a rim-drive.

The HRX w/ 3D arm on here is a very good deal.  14K list for around 8K
For that arm, an incredible match would be either the Transfiguration Axia or the Ortofon Cadenza Bronze.  I've heard both on that table with that arm....

If that table really has never had a cartridge installed, I'd recommend jumping all over it before someone else does......

I wouldn't bother with the classic 4.  The differences in motor/plinth between the tables are night and day and the money isn't.....

mmporsche....You are obviously a person of discriminating taste (I too own a Porsche).....I also own a 3D VPI arm and have had experience with many of them....the 3D is a definite winner.  I would put a top of the line Lyra (Atlas or Etna...they are both wonderful...the Etna is a bit more musical or less analytical (not putting down either of them).  If you take my suggestion (the HRX is a great table....can be made better by the addition of a rim drive, Classic Platter..all in due time)

mmporsche, you have many good options at this price-point, especially if you consider used decks. I have both a Brinkmann Oasis and Nantais Reference II and can recommend them both. The Oasis has a bit more focus and precision, but you absolutely must place it on a top-flight resonance platform to hear what it can do. I use a Minus-K. The Lenco has a bit more drive and authority at the expense of the nth-degree of the Brinkmann's precision in articulating instruments. (We're talking minor differences here.) And because of its mass (105 lb), the Lenco is less needful of a pricey resonance platform. Speed stability is a toss up, with both holding speed equally well, according to my KAB speedstrobe.

BTW, I see there's an Oasis listed at a good price. (No affiliation with the seller.)
