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?

I've put it down for between 6th and 13th February this year.  Not sure what the hold up is.  Maybe beryllium is in short supply?  Anyway, I have paid a 10% deposit and will be asked for the rest before the distributor ships it from Melbourne.

Meanwhile the Presto order has gone in ...4 x SACD, 16 x CD, 4 x vinyl.  Most of the cost was for the vinyl!

@richardbrand not surprised that most of the cost in music order was vinyl. 
As for the cartridge…I’m surprised it’s not in stock but on a flip side hopefully you’re getting a freshly made cartridge.

It is possible that all available stock was shipped stateside to avoid t increases!

Those vinyl records of Sir Adrian Boult conduction the Elgar symphonies were still where I spotted them, so I bought them both.

They are stereo - quadraphonic recordings and I don't know how that affects the sound quality in stereo.  Any ideas?
