various detail shots of phono cartridges, and headshells I have owned at one point or another....
Also included will be cartridges I may not have had here, but am interested in.
ADC Audio Dynamics
A list of compliance ratings and stylus configurations on different ADC XLM models:
ADC ST Series: (Cartridge comes packaged with and mounted to a carbon fiber headshell that plugs into the ADC LMF-2 tonearm.
Btw, the ST series cartridges are simply removed from the packaged headshell and then can be used in different tonearms of appropriate low effective mass design.
These two came with an SME 3009 S2 tonearm I purchased from an eBay seller in France. I haven't heard these.
Design: Moving Magnet. does not require step-up
At the lower end of the price scale there is this model. It is a universal mount. Fits either 1/2 inch mount or 'P' mount. To fit 'P'mount, undo the screw on the back part of the body and remove the rear adapter frame.
Review pending. Here is a potential world-beater for those who would care to put it in one of Uwe's wood bodies, then match it up with the appropriate step up transformer. It likes a fairly heavy toneam. Design dates to 1962. Initially intended for broadcast use. Still in production. Several variations were made over the years. Currently the two versions still being offered are the DL-103 and the DL-103R. The difference is in the copper coils. The "R" uses a higher purity copper, called "6-nines copper" (99.9999% pure) and has a different load impedance. The 103 and 103R share same family sound but offer slightly different tonal character and with the "-R" offering slightly improved upper frequency detail along with a smoother overall tone quality.
output voltage: .2 mV Load: 14 ohms (-R) and 40 ohms (DL-103) both require voltage step-up*
Analogue Labs Aluminum body for the DL-103 and DL-103R:
More about the Analogue Labs body when I get around to mounting a DL-103 into it.
More info here
EMT TSD 15
design: Moving Iron. Output Voltage: 5 mV, load: 47Kohms, does not require step-up
This cartridge does nothing wrong. And for a retail list price of ~ $1900 it should not.
output voltage: .34 mV, Load: 10 ohms requires step-up*
UV-15, D 2000-Q
brand, model: Realistic R1000 ED
type: moving magnet
This cartridge is missing the stylus assembly. A new replacement should be available somewhere.
OEM from Shure. Judging by the body shape I would compare this model to a Shure M75ED or M91ED I am not really certain. Anyone have definitive info on this?

This cartridge has character. Dynamic. Expressive. Emotional. Nice midrange. Bass is a little tight but extended and textured. Nimble. Fast transients. With the right record, can raise the hairs on the back of your neck. Not a particularly great tracker.
Output voltage: .4 mV. Load: 10 ohms, requires step-up*
It also can be killed with blunt force:
The mishap occurred when the tonearm/cart was allowed to bang against the side of a platter. At the time the damage wasn't recognized. The stylus is very small and can't be seen without magnification. Interestingly, the cantilever remained straight. Damage has caused the cantilever and stylus to rotate within its mount. Obviously, the cartridge is unplayable as is.
cantilever found to be "loose". The cantilever could be carefully rotated back into position using a fine tweezer. After removing the cantilever, and viewing it under as much magnification as was available, I was able to conclude that apparently the adhesive bond failed. The fix, should be obvious. Add glue and stick the cantilever back into its pipe. Here are a couple of shots after re-glue:
But the Shelter wasn't right. Sound Quality was off. So I shelved it untill............
I found someone who could make a proper repair

This version of the V15 was made in Mexico. Now it is out of production. This is the last of the Shure V15 series. It is a nice sounding moving magnet cartridge, if a touch rolled off in the high frequencies. Capacitance of your tonearm wires need to be around 250 pF. Load = 47kohms. Static compliance is approx. 20 x 10-6nm. Compliance of this model is not as soft as earlier V15 versions. It mated well with my Rega tonearm.
Output voltage: 3 mV does not require step-up
Sumiko Blue Point Special
above: a dead Blue Point Special, sigh.
but here's a virtual one.
High Output Moving Coil. Load= 47Kohms. Works with standard MM phono stages common to most 60's,70's and 80's good quality stereo receivers.
In the late 1990's this cartridge received rave reviews within the audio press. Based on these recommendations I purchased the above sample. In practice I found that the cartridge was a good compliance match to the Thorens TP16 (mk 1) tonearm on my TD160. I also noticed that there was absolutely nothing remarkable about the sonic performance of this cartridge. Average sounding. Not bad. Not great. After about a year I managed to lightly snag the cantilever with a dust cloth. Above photos show the damage. The cartridge could have been re-tipped but I didn't feel it was worth the bother or expense. Didn't care. I would rather have saved initial purchase money for something else.

Notes on cartridge compliance rating systems:
The Dynamic rating:
There is at least one thing the Technics EPC 205C-II and a Denon DL-103R *have in common. Their rated compliance value is achieved through the same kind of test procedure where: dynamic compliance @100hz is measured by determining the minimum VTF at which the onset of mistracking occurs when playing a 50um amplitude 100Hz frequency modulated groove. We can find reference to this explanation from noted tonearm manufacturer H.H. Moerch at his website where he has published a downloadable pdf we can refer to.
Here’s a link to that document:
http://www.moerch.dk then go to: homepage/instructions/cartridge armtube combination list)
In his paper, Moerch offers a simple means to translate from the dynamic @100Hz value to the more common 10Hz rating that many/most cartridges use. Simply take the rated "dynamic" value and multiply by anywhere from 1.5 to 2. The Technics rated dynamic compliance of 10 * 10^6 cm/dyne, multiply by 2 = 20 at the 10Hz method. And this is a value that can be plugged into a formula offered within the same Moerch paper that can be used to predict the tonearm/cartridge system resonance. Here it is:
Using the above formula and plugging in the required values from the Black Widow spec list I came up with a predicted arm/cartridge resonance at 10.9hz. This proved to be close to reality as when using the HFN-001 test record, side 2 track 2 the measured resonance was 11Hz. The formula appears to work and so did H.H. Moerch’s simple method of conversion (times 2) noted above.
The Static compliance rating system: to be added
The 10Hz compliance rating system: to be added
footnotes on compliance rating systems:
*and many other phono cartridges. When the compliance rating says "dynamic" we presume this is what they mean.
*Generally, low output moving coil cartridges have a reputation to be the best sounding of their type. But the main disadvantage is that the output voltage is so low it requires a step-up device in line between itself and the phono-preamplifier. Another critical factor is the introduction of noise and hum into this very fragile and vulnerable signal. Great care must be taken to transform and deliver the signal cleanly into the phono-preamplifier. more info
