Most hyped turntable, tonearm, and cartridge?

Like Millercarbon said, old things tend to go up in value due to rarity and collectability in our throw it out if it's broken society.

Technologies that get perfected incrementally are what you want. Just like 911s get a little better all the time, their owners have their preferences, whether they are air cooled, turbocharged, sunroof, cabriolet (convertible for the non-car folks). Regas (especially their arms) get better all the time, for 40 + years.

When technologies disappear from new production like an idler drive, there is a reason for that. I guess some people want to pay $23,000 for a turntable worth $2K just like some people will pay $900K for a new build of an old 911. They want that nostalgic look that is in style.

True audiophiles don't care how things look, only about the sound. Having it look nice is a plus, but IMHO it should not be part of the equation unless all else is equal.

Finally to answer the OP question, when I first started with audio equipment in college in the early 80's, all you heard about was that the Linn Sondek LP-12 was the ultimate turntable. Now there are so many good ones, it's hard to say what it most hyped. Also, the prices of some have gotten so stratospheric that they have become status symbols. VPI told me that some of their customers told them that one of their high end tables was too inexpensive. He thought it should cost $40K instead of $20K. I kid you not. They were from Asia somewhere and were trying to impress their friends.

I own a Aries turntable that I bought 20 years ago , Harry told me in a conversation . That the paint job on it ,which is triple piano black ,would increase the price , make that double what I paid,To make it today, l still own it. But always looking . Now let’s see. ENJOY

OK. My turntable is better than your turntable, my turntable is better than your turntable. Come on sing along. My turn.....

Sota Sapphire V with proper setup and affordable arm / cart, will sound wonderful as well. 

Excellent early point made:  don't mess with antiques! if you have a choice.  I run 2 full systems at home.  One is a 1978 fully maintained and updated Thorens TD-160 with Ortofon MM Bronze cart.  The other is a new Rega 6 with the same cart.  The Rega is now at about $3,000 with addtitions like a tone arm lifter and high end belt and the Thorens is about $2,500 with many up dates too.  I have loved the Thorens for over 25 years and the Rega for much less.
Most important difference is in the "material science" and advances made in everything down to how they 'draw copper wire' has changed.  If I could replace everything on the Thorens with the same materials used on the Rega and I would have the best ever.  
If my house burned down tomorrow and I moved into a new place and could replace one set of stereo gear, I would buy the Rega.  In a heart beat.  Old loves are dear, but old.  I am old and I know it is not to be desired.  Inch for inch and dollar for dollar the new stuff is way, way better if you shop smart.  As long as you stay with analogue and vinyl it is hard to get it too wrong.  
P.S.  I am a fussy listener but cannot really tell the difference in music once you get much over $3,000 into a turntable.  Fantastically expensive equipment does much to impress, but not by the sound.  This is ever more true about old equipment.
