About the
Audio Note AN-S4L.
The AN-S4L steps the SUT line up to Level 3 — mu-metal core with silver winding, suited to the IO-2 cartridge and an M3 RIAA phono stage.
Audio Note AN-S4L across 4 variants.
Four hand-wound step-up transformers for matching Audio Note UK moving-coil cartridges (and any third-party low-output MC) into the 47 kΩ moving-magnet phono input of an M-series RIAA stage or an OTO Phono. The conductor moves from silver-plated copper at the entry through pure silver at the top. Each SUT is tuned to a specific cartridge impedance range — Audio Note will recommend the pairing.
| Model | Conductor | Step-up Ratio | Tier | Notes | Tier |
|---|---|---|---|---|---|
| AN-S1 | Silver-plated copper | 1:10 / 1:20 (selectable) | 1 | Entry SUT — pairs with IO-1 / Ortofon-class MC | — |
| AN-S4L | Mu-metal core, silver wire | 1:10 / 1:20 | 3 | Level 3 silver upgrade | — |

| AN-S8L | AN reference silver | 1:10 / 1:20 / 1:40 | 5 | Top-of-line reference SUT | — |
