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?

For the record, the producer of a Phonostage I have as one of my Phon' Options also produces a Generator for the DS Audio Cart's.

An individual in the UK, with what seems unlimited fund restrictions when it comes to DS Audio, has used this alternate generator with the most expensive of DS Audio's range and does not have any comments made that suggest something is amiss.

I'll give another vote for the London Decca design. The top of the line Reference is as good as any cartridge I have heard.

Being in Australia, hopefully you have checked out Garrott Brothers which is an Australian company

Hi Neil

No, this is a new name to me!  I also had not heard of Dohmann Audio turntables until @lewm pointed them out through this forum.

I should get out more, I guess ...

Oops.  I slipped up on the price range for DS Audio, because not all prices included the equaliser stage (although as Neil has pointed out, these can be sourced from other manufacturers).

So try AUD-4500 to an eye-watering AUD-105k

I've heard the DS W3 on a VPI Classic with a pair Magico S5Mkii driven by CAT amps, and the system sounded pretty amazing to me.
