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 think I know where I can find used vinyl records of Sir Adrian Boult’s Elgar symphonies. I’m tempted ...

Boult was a great Elgarian and superb in Vaughan Williams, but I don’t know how he did it!  Whereas Barbirolli marked up the scores for every player in his orchestra, and was exciting to watch, Boult seemed to me to just stand there and wave both arms in synchronization - something he deplored when taking master classes for conductors.  But there’s no denying his results.

Going right back, the electrical recordings made by Elgar himself at the then new EMI Abbey Road Studio are available on CD.  The sound quality in mono is better than expected for the early 1930s but the performances are definitive.

The conductor I recall most vividly from my youth is the Russian Kyrill Kondrashin, who conducted without a score and without a baton.  His thumb seemed about two feet long.  Hastings was a provincial warm-up for London concerts, and you could see Kondrashin bringing every instrument in, and shading the dynamics by hand gestures.  Pretty much the exact opposite of Boult, but both got brilliant results.

Can’t wait for my optical cartridge to arrive to get the thread back on topic ...

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!
