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 watched The Absolute Sound review of the Umami Blue where Tom Martin compares the Umami Blue to DS003

Thanks for sharing that!  If I ever get the urge to go MC, Umami Blue should be on my list.  I looked up the price in Australia and discovered Johnnie Walker Blue Label Elusive (sic) Umami Limited Edition - I could buy two bottles with the change left over from my bargain DS003, compared with list price for the Hana!

The Absolute Sound is very keen on DS Audio for its clarity and cleanness (things I am interested in) but recognises that it does not sound particularly analogue.  We all look for different things and there's nothing wrong with that.

One of my takeaways from the video is Tom's comment that when the importer recommends something like a phono stage, they (TAS) usually follow that advice.  That's exactly what happened to me with the SoulMate recommendation!  My importer could have simply sold me the DS003 Equalizer.  Right now, I think going SoulNote was the best sonic decision I have made so far on my vinyl journey.

A while back, we were discussing Bruna Walter's Columbia performance of Mahler's 9th Symphony.  Having owned the records for about 60 years, I ordered the CD which I am playing now.  No clicks, pops or scratches.  Still waiting for his earlier mono recording to arrive (on CD).

ChatGPT says it better that I can

Solid-state amplifiers manage true balanced operation by implementing a fully differential signal path from input to output, which involves using dual, mirrored, and identical circuits for both the positive (hot) and negative (cold) signal phases [4.2, 4.5]. This approach requires twice the components—transistors, resistors, and capacitors—to ensure the signals remain 180 degrees out of phase, allowing the amplifier to cancel common-mode noise and minimize distortion

CatGPT is completely wrong. You might ask it for its source, if you're interested in accuracy.

A differentially balanced amplifier does not require "using dual, mirrored, and identical circuits for both the positive (hot) and negative (cold) signal phases ..."

I am not interested in debating with AI, so I'm done with this discussion.

@richardbrand ha! Never saw that Johnnie Walker Blue Elusive Umami anywhere! 
I’m more of a bourbon guy myself. In scotch I prefer single malt from Islay - Lagavulin, Lafroaig, Ardbeg. I don’t find Johnnie Blue to be all that great especially for $250-$350 (for this umami edition) range. 

Here in the US the Hana Umami Blue is $2,500. And DS003 is $2,750. That’s two bottles of excellent bourbon AND a bottle of Lagavulin! Hehehe 

Hana Blue will most likely have a slightly different sonic perspective than DS003. By no means I dislike a clean delivery. As a matter of fact my Hana ML paired with the Whest phono stage is by no means warm sounding. I’m expecting the Blue to walk that fine line but slightly more careful than the DS003, as the review pointed out. 

@audphile1 

Lagavulin for me, but must be at least 16 years old.  They blend it into the more expensive Johnnie Walkers which is as criminal in my book as adding ice!

My partner bought me a 16-yo Lagavulin, but dropped the bottle getting out of the car.  It was such a tragedy, the shop replaced it free-of-charge.  I’m still smelling the tarmac.

’Sources’ tell me that the further you are from Scotland, the cheaper scotch becomes.  OK, it was the scotch shop at Heathrow Airport telling me I would be better off buying it on landing in Sydney, but not a bad rule-of-thumb

Thank you for explaining that @richardbrand 

So older DS models are the ones that needed the extra wires?
