The ADC XLM cartridge - this is the only cartridge we have seen that is really capable of tracking almost all stereo discs at 0,4 grams.
The Sound Authorities go on to say: "the XLM went through the usual torture test at 0,4 grams (some models require more than a gram)….the XLM is capable of reproducing anything found on a phonograph record." "the CBS STR-100 test record showed less than ±1,5 dB variation up to 20,000 Hz … response is within ±2 dB over the entire range, and Frequency Response is exceptionally flat."
"Distortion readings, are almost without exception better than those for any other model we've tested, … the XLM has remarkably low distortion in comparison with others, …at 0,6 grams the distortion was low - under 1,5 percent."
"The XLM could be instrumental in lowering the input noise from the first stage of a modern transistor amplifier, … the cartridge had very good shielding against induced hum."
"This would be a very hard cartridge to surpass at any price, … we found it impossible to attribute superior sound to costlier competing models, priced as it is, it is a rel bargain in cartridges."
