What innovative, unconventional cartridge designs can you recommend?

Most cartridges have a stylus and cantilever where the transducer (magnet, iron or coil) sits on the far end of the cantilever.  What other designs are there?

I am mindful of two designs which put the business end right on top of the stylus.  The first is the moving coil (MC) Audio Technica AT-ART1000 which places two tiny coils, each 0.9-mm diameter, with eight turns of wire directly above the stylus.  Australian price is about AUD-7000 and there apparently is a newer model, slightly less exxe. the ART1000X.  This has square coils for a bit more output, and threaded mounting holes.

A downside is that stylus replacement involves a factory maintenance program and the Australian website page describing this service does not exist.

Another design is optical, exemplified by DS Audio's range.  While these still need a stylus to trace the groove, the signal is produced by reading the intensity of light produced by a Light Emitting Diode (LED) hitting two sensors.  Between the LED and the sensors are two 'shades' mounted above the stylus which change the amount of light as the stylus vibrates.  These cartridges need a special "photo-stage" to replace the conventional phono-stage which is an additional expense.

Australian prices including photo-stages range from AUD-2,150 for the DS-E1 to the DS Master 3 at approximately AUD-40,800, which is a bit outside my price range!  Where is the sweet spot?

What other way-out designs are there?

What is innovative about the Art 1000? It is Miyata san’s reimagining of the Neumann DST design of the 1960s, a very, very, old design

You have to blame me for not knowing that.

However, it seems to me that the end results are totally new in virtually every respect.

It is quite possible to re-invent the same thing independently, for the same good reasons.

The Neumann, and the ART1000 are attempts to make traditional MC designs approach the tip-sensing goodness of the Deccas.

Can there be a better spot for a nice big coil than wrapped right around the portion of the armature holding the stylus?

But the Neumann and ART1000 both have cantilevers wafting around upon which the coils are mounted..

The closest MC to the Decca is the original Ikeda 9 ( from the 80s' ) that has no cantilever, and the coils are wrapped around a hoop right next to the stylus, which is mounted at the apex of the hoop.

Superb cartridge - I've had a few, still have one.

I've set up at least 30 Deccas, both original and modified, the original Ikeda MC and Decca's are certainly the quickest and most direct sound of any of the modern cartridges.

The Dynavector Karat Nova 13D, with its 1.3mm cantilever is close. I have owned one since the 80's - thrice rebuilt by Dynavector, last rebuild with micro ridge stylus, which was a considerable upgrade over the previous pathfinder in terms of resolution - it will see off most of todays top cartridges.
