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?

Yes, your rave about Bruno Walter set me off!

I already have micro-line styli in both my table/cartridge systems, so I don't expect any improvement from that.  I did not go with the cheapest DS Audio cartridge, because I wanted at least a line-contact stylus.

PS: did you manage to unpack "acacia missing identity"?

@richardbrand 

Acacia mistaken identity?

Yep

And bought Bruno Walter’s Mahler 2nd  with NY Philharmonic on discogs. My first purchase there. VG+ rated and looking forward to hearing it on vinyl. Hopefully the incoming Humminguru will make it more listenable. 
 

Your DS cartridge is DS003 correct?

@audphile1 

Your DS cartridge is DS003 correct?

Yep, it will be when it finally arrives!  I could even allow myself to get excited ....

@richardbrand received the double LP of Mahler’s 2nd with Bruno Walter and NY Philharmonic. Immediately threw it into my new Humdinger ultrasonic cleaner. 
The LP was advertised as VG+. I’m listening to side 1 and so far it’s great. I’m surprised with the recording quality actually. Performance is, as expected, first rate. Vinyl is relatively quiet so far. I’m blown away by the performance of the orchestra. 
What’s strange is LP1 is parts 1 and 5, LP2 is parts 2, 3 and 4. Was this meant for some sort of juke box?

This is just odd…I guess time wise this was the only option?

LP1:

  • Side 1:   I
  • Side 4:  V

LP2:

  • Side 2: II, III
  • Side 3: IV, V
