A few exceptionally good high-compliance cartridges for your lightweigh tonearm (within your budget):
ADC TRX-2 IM (Induced Magnet) with Sapphire Cantilever and Vital diamond. ADC (Audio Dynamics Corporation) under a new ownership continued making High-End cartridges. To develop ADC sound they hired Nakansuka San from Japan, now he’s the owner of ultra high-end brand ZYX. You may think that ZYX is this brave new phono cartridge manufacturer, but its founder and chief designer, Hisayoshi Nakatsuka, is far from being a newcomer. Nakatsuka San has been working for Namiki, Accuphase, Adcom, Ortofon ... Back in the 70’s top of the line ADC TRX series was designed by Nakatsuka San (ZYX). Flagship models ADC TRX-2 with Sapphire cantilever and Vital II nude diamond is one of the best ADC cartridge designed under new ownership.
Sony XL-50 MM with Boron Hollow Pipe Cantilever and Super Elliptical tip, unique jointless delta-type core. My latest discovery, amazing cartridge.
Pickering XSV-3000 MM with Stereohedron tip (just like Stanton 881s) is the best and the cheapest all rounder. I have a spare cartridge and spare sealed NOS stylus.
