Thanks for the German article describing experience with the DS003 and Mr Nixie 'food parts'. I had to have it translated because my German is not good enough!
I am confused by the initials TOTR. What do they mean?
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?

Fair enough. Internal Z is part of the total circuit impedance. I have only used MM cartridges where the load impedance is around 48-kOhms and there effectively is no current! I note that Van den Hul have an interconnect cable with resistance of 26-Ohms per meter which they say is irrelevant. The cable, based on carbon nanotubes, is the best sounding they make, according to their website. But would it even work with LOMC? |
@richardbrand I believe TOTR is 'top of the range' (top of the line equivalent). |
