ADC RLX-II Stylus
That crisp, whisper-quiet high end on your vintage pressing? This tiny diamond might be why.
Overview
The ADC RLX-II stylus is a replacement needle designed specifically for the ADC LX-II phono cartridge, a cartridge that once flew under the radar but has quietly earned loyalty among analog diehards who value precision without clinical sterility. While details about the original ADC product line are scarce, the RLX-II replacement—offered today by LP Gear—keeps these older cartridges spinning with confidence. It’s not a flashy part, but it’s a critical one: a special elliptical diamond tip that’s tasked with riding the tight curves of your vinyl grooves, translating decades-old modulations into something that still feels alive.
Owners seeking to revive a neglected LX-II cartridge will find the RLX-II stylus as their logical, and perhaps only, path forward. It's not just any elliptical—it’s a “special” elliptical with scanning radii of .0003 x .0007 inch, a shape engineered to dig deeper into groove walls than a standard elliptical, pulling out detail that a spherical tip would simply gloss over. And because the diamond is highly polished, it’s believed to reduce high-frequency distortion and wear on records, though the original ADC engineering notes remain lost to time.
While we don’t have manufacturer specs for the original cartridge—no output voltage, no compliance, no frequency response—the replacement’s design speaks to a particular era of analog thinking: not overly warm, not aggressively bright, but aiming for accuracy with a touch of refinement. The ADC LX-II cartridge body, reportedly sharing its form factor with the QLM, VLM, and XLM models but finished in all black, suggests a family of cartridges built for consistency and ease of installation. And while the RLX-II stylus itself doesn’t come with a manual or spec sheet, its continued reproduction implies demand—meaning someone, somewhere, still trusts this setup to deliver the goods on their turntable.
