ADC SX5 ()

Name: ADC SX5
Brand: ADC

That crisp, clean midrange and reliable groove-tracking in a no-frills package — if you’re spinning 33s and 45s without fuss, this little conical diamond tip gets the job done.

Overview

The ADC SX5 — sometimes seen as the SX-5 or even SX-5E/SX5E — is one of those quiet workhorses that never made headlines but showed up in plenty of turntables when you needed a dependable, no-surprises phono cartridge. It’s not a high-end elliptical tracker or a super-compliant audiophile darling; it’s the kind of cartridge you’d find in a solid mid-tier belt-drive or even some professional setups where reliability mattered more than exotic specs. The stylus itself is a conical diamond tip, highly polished, which tells you everything you need to know: it’s built for durability and consistent contact with the groove, not microscopic high-frequency retrieval.

Owners report it delivers “precision tracing of record grooves and good rendition of voice and music” — which, for a conical stylus in this class, is about as glowing as it gets. It tracks cleanly through moderate wear and doesn’t demand perfection from your setup. It’s compatible with 16, 33, and 45 rpm records, making it versatile for broadcast or DJ use, but explicitly not suited for 78s — so don’t go digging into your granddad’s shellacs with it. There’s no word on who actually manufactured ADC cartridges or where they were made, and the brand remains something of a ghost in the vintage audio world — not to be confused with the modern medical device company of the same initials. This ADC belongs to the analog era, and that’s where it stays.

Collectibility & Value

The ADC SX5 isn’t a collector’s trophy, but it’s far from forgotten — especially if you’re trying to keep an old turntable running without a full retrofit. Replacement styli are still available, though prices vary: one listing shows a new stylus at $27.95 (LP Gear), while another retailer (My Needle Store) lists it at $56.99 — a significant spread that might reflect packaging, branding, or regional differences. Used full cartridges pop up occasionally: one was listed for €29 on Hifishark.com in December 2025, another stylus-only listing (called “Puntina per ADC tipo SX5”) went for €32 in October 2023, and Jukebox Revival currently lists the cartridge at €26.00 as of their 2026 copyright date. Given the lack of data on common failures or maintenance quirks, owners tend to treat it as a “replace when worn” item rather than a serviceable unit. If you’re hunting for one, you’re more likely to find it as a functional spare part than a vintage audio gem — and that’s exactly what it was designed to be.
