There were mainly two high-end cartridges that Sony were renowned for in the 80s and both were LOMCs.
The XL-55 is perhaps the best known although the XL-88 and XL-88D (with one-piece diamond-cantilever/stylus construction) is the better model IMO.
The XL-88D was the most expensive cartridge in the world when it was released and sold in Germany for 7500DM which was more expensive than Volkswagen in its days.
There are scant technical specs available on the XL-88 but I found these:-
Specs:
Type: moving coil
Output Voltage: 0.4mV
Frequency Response: 10Hz - 50kHz
Tracking Force: 1.2-1.8g
Mass: 6.8g
Channel Separation: > 33dB
The compliance is rather high for a MC at 20-6cm/Dyne and they both sport Hyper-Elliptical styli.
As the XL-55 and XL-88 appear to share much of their construction, I post it HERE as it's interesting 🤔
The Signet TK-7SU is essentially the same cartridge as the TK-7Ea and TK-7LCa except with a Shibata stylus instead of the Line Contact of the LCa.
