Up for sale is my PRO-JECT MC Step Up Box S3, SUT for Moving Coil Cartridges. It's in excellent condition and has just 1 very faint hairline scratch on one side, see photo. No other dents, damage, etc. to the faceplate and case. It functions perfectly (nothing really to go wrong) and I'm only selling it to facilitate an upgrade. It's a current model and retails for $549.00.This Pro-Ject piece has been displayed in a non-smoking, incense free, child free, pet free and cologne and perfume free home and is guaranteed to be free of any greasy fingerprints, strange odors or any other funk!This sale includes just the SUT and a copy of the owner's manual (no original box, sorry).Read my stellar feedback and purchase with complete confidence as my feedback speaks for itself. This unit is listed elsewhere and subject to prior sale and I expect it to sell quickly!It will ship via USPS for a flat fee of $19 to anywhere in the CON USA within 1 day of cleared payment.
Against the obvious alternative at this price point — a generic phono tweak or just putting the money toward cartridge upgrades — US$359 is a reasonable buy, though not a steal, versus your used-market anchor of a US$198 median and US$445 75th percentile. It sits comfortably above the middle of the pack but still below the upper quartile, so this reads as fair-to-strong rather than bargain-bin.
What makes it worthwhile is that a good step-up transformer can bring real gains with low-output moving coil cartridges: better drive, quieter background, and a more natural, unforced presentation than many active gain stages. If the unit is clean and complete, the upside is in getting a respected, simple analog piece that can stay in a system for years; at this price, I’d just confirm the original box and any adapters are included, since those matter more for resale and convenience than for the sound itself.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Pro-Ject Audio Systems traces its roots to 1991 in Austria's Weinviertel region, north of Vienna, where founder Heinz Lichtenegger launched the brand amid the CD revolution. Kicked out of music school as a youth, Lichtenegger channeled his passion for analog sound into affordable, high-quality turntables at a time when vinyl seemed obsolete. His debut Pro-Ject 1, hand-assembled in the Czech Republic, earned rave reviews as a top high-end device, igniting a success story that relocated headquarters to Vienna before returning to Mistelbach in Lower Austria.
The brand excels in turntables, establishing itself as the world's largest and leading producer in that category, while expanding into a full spectrum of hi-fi components since 2000. Offerings include amplifiers, DACs, headphone amps, speakers, cables, and phono stages, all emphasizing essential sound reproduction with durable materials and minimalist design. Manufacturing remains European—primarily in Czechia, Slovakia, and Germany—prioritizing sustainability through local sourcing, short transport, and products built for longevity.
Pro-Ject holds a commanding niche as the go-to for mid-tier audiophiles seeking boutique European craftsmanship without extravagant pricing. Distributed in over 80 countries, it appeals to vinyl revivalists and discerning buyers who value analog purity, innovation, and value-driven performance over flashy excess, cementing its reputation as a pioneer in accessible high-fidelity.
