What innovative, unconventional cartridge designs can you recommend?

An improved Quality Control at the assembly end might develop as an outcome

Now who is making assumptions!  This is quite insulting to DS Audio.  As far as I can tell, the only person on this site who regards you as an authority would be yourself.

You have no interest in buying DS Audio or an ART1000, so why not keep your unhelpful comments to yourself.

AnalogMagik Reports are snippet of products released into the Cartridge Market, what is read, is for the best, if worn like a loose garment, it should not be attached to being an authority on the Quality of released products.

I would trust the AnalogMagik reports more than lunatic ravings of an uninformed luddite. I have not heard of any significant issues with regard to quality control of the DS Audio cartridges. From what I have personally seen, the build quality looks to be very good.

It was expected and as always - No Beef from my end, live and let live.   

@pindac Has a keenness to experience a ART 20 as well as the ART 1000X, a Ortofon Verismo and a MSL Platinum, with the main interest in the ART Models.

My own Transducers immediately available and the designs being put in place as a result of others undertaking investigations, that can be used with them are also enough to keep myself totally interested in Cartridges.

The DS Audio Range of Cartridges which I have followed for approx' 4 years has not revealed anything that creates the earlier stimulus I had to experience them, which was enough for me to venture on a 600 mile round trip to experience them in use. As already stated " A owned Cartridge still in use today, when compared to the DS  Audio Cartridge, proved to be the much better device to create an indelible musical encounter. This was not a thought limited to myself, a selection of other attendees of which one was a audio media journalist were quick to inquire about my Cartridge and the service who produced it.     

@pindac You haven't commented on what I said. Or did I misunderstand your issue with exotic cantilevers on DS Audio cartridges?

Me to! 

AnalogMagik does far more than @pindac 's rather incomprehensible dribble suggests:

In particular, they run extensive turntable and cartridge tuning and rebuild services - see Will AnalogMagik work with my equipment? which includes: 

12) Can you give me some hints as to what cartridges, tonearm, and turntable combinations will be easier to measure incremental changes?

For cartridges, we find My Sonic Lab, Haniwa, Air Tight, Ortofon, Lyra, and Phasemation to be some of the brand names that stand out as having very consistent manufacturing quality.  Optical cartridges such as DS Audio also measure very well. These brand names also have very low channel imbalance, which makes crosstalk analysis a lot more accurate.    Two names that I find to be very responsive to adjustments, are MSL and ZYX

On the other hand, we find some other cartridges to measure very poorly, some have significant channel imbalances.  Other Cartridges with stylus zenith issues, channel imbalance out of the factory, and various suspension problems tend to be less responsive to adjustments, or they may exhibit very mediocre numbers.  The bottom line is if the cartridge is bad, do not expect to detect incremental changes easily.

Tonearms that have high machinery precision, with fewer wobbly parts tend to provide efficient energy transfer, they tend to register much lower baseline distortion levels.    Tonearms with lots of moving parts that fit together poorly tend to measure very poorly.

For turntables, those that have better isolation tend to measure a lot better.     Idler wheels, rim drives, and older tables with lots of mechanical moving parts tend to measure very poorly, they produce a lot of vibrations which makes baseline distortion levels high.    It is difficult to detect incremental changes with these tables.

Come in, @billstevenson
