A turntable that plays all types of music well

Ridiculous question. I like @millercarbon's comment....but he forgot that you have to adjust the VTA when you change cartridges.....and don't forget to clean the record for an hour on your Degritter.

Sorry. Right. Don't know how I missed those. Probably engrossed in this design I have for remote control VTA adjustment so you can change VTA for every type of music and even song to song. With memory function so once you figure out which table, arm, cartridge, interconnect, phono stage and (did I leave something out? It feels like I left something out?) then VTA and of course VTF can be locked in and programmed to return to those settings, saving untold man-hours that can then be devoted to mechanical chemical ultrasonic three stage purified water cleaning and optimal humidity drying. Which oh by the way it turns out the classical LP requires 50% humidity at 78 degrees while rock dries best at 40% humidity and 84 degrees. You can do the other way around but the strings will sound a bit dry.

Well Tempered Versalex or the newer Amadeus 254 GT. I own the Versalex and it plays any music quite well!

The retained Tonearm and Cartridge are looking most capable to show the capabilities of any TT they are coupled with.
More importantly the Tonearm and Cartridge are also looking quite capable of defining the Bass Authority a Idler Drive TT is able to produce.

I am quite familiar with DD, Belt and Idler Motor Drives on TT's and will listen to them all irregularly,  prior to COVID this was achieved a few times within a year.
As for the Idler Drive TT's, I am quite familiar with these and have heard these regularly in a variety of systems, where the TT has been set up mounted on different Plinth Materials / Plinth Designs and Mounting Configurations, as well as all models will be coupled with a different Tonearm and Cartridge. I have also heard side by side Idler Drive Brands such as Lenco vs Garrard and Lenco vs Thorens and alternatively Lenco vs DD and Lenco vs Belt Drive.
What becomes quite noticeable when being demonstrated a Idler Drive in a system, and as a comparison to my owned PTP Solid 9, is that their is a sonic signature to be discovered where it is perceived the Bass is with authority not usually met in any other TT with a different Motor Drive.
The Bass is very noticeable in the presentation.
As you are with a JN  Plinth I am assuming you have experienced the Bass Authority reigned in and with an improved control although very present, it is I am assuming presented with a tightness and decay that a lesser plinth design may fall short on being able to offer.
My own PTP Solid 9 has a very well controlled Bass Note when compared to some of the GL75 Variants of the design I have been invited to listen to.

If a person is Wed to the Idler Drive (many are dedicated to this design) presentation and is satisfied with the Sonic Signature the Bass is offering, then I can't see any other TT fulfilling the role, as the noticeable differences in the Bass management will become quite evident in a short space of time. Listening to a few cherished LP's that all of a sudden sound anaemic when recollecting the replay compared to the Idler Drive will potentially be a distractor and this in itself will dull the moment.

As for the individuals who seek out a Sound Quality that satisfies a unique personal preference, once discovered it becomes hard to veer of course, from my experience, the search becomes a venture into how to Hone and Optimise the experience that is already quite satisfactory.  
If the JN Design is wished to be moved on and another design is off curiosity.
A much cheaper method and one that I am sure will be totally satisfying to your SQ preferences, would be to purchase a GL 75 PTP 6 Plate and produce a DIY Variant design for the GL75, I have priced this method myself and with the PTP 6, Donor GL75, SPH Platter Bearing, Plinth, and Speed Controller Unit I was calculating at approx' £1100 GBP which is close to $1500.
This is a DIY version of a PTP Solid 9 and I am confident in saying that it is a difficult design to improve upon when used as a comparison to other Idler Drives be it GL75 Variants, Garrard or Thorens.
After a few years usage and if a desire to change takes place there will still be a $1000ish in the sale.    
      

Bad move karmapolice. As much as I like the design of the tonearm is as much as I dislike the turntable. First of all the marketing is plain stupid. The suspension's design according to the marketing in almost no suspension at all. Vibration does not occur in the vertical plain only. It occurs in every plane and the most serious anomalies occur below 10 Hz. Rumble is always an appropriate measurement they are just embarrassed over their number. Lastly, it's construction is cheesy and it is ugly. 

If you had already made up your mind on a turntable why did you start this thread? You wasted time in the lives of people trying to give you their best advice.
