Pro-Ject RPM 5 Carbon (U.S. Gloss Black / Sumiko Amethyst MM package) review

This assessment is for the U.S.-facing Gloss Black Pro-Ject RPM 5 Carbon package identified with a Sumiko Amethyst moving-magnet cartridge. It draws on Pro-Ject's model page, information sheet and manual plus the exact U.S. item listing; it is not an ownership account, listening test or measurement report. The documents reveal a real technical ambiguity: the current manufacturer page calls the platter acrylic, while the product sheet's specification table says MDF even though its feature bullet also says acrylic. I leave platter material unresolved rather than choosing the more appealing claim.

System matching: cartridge-level signal, no built-in stage

The RPM 5 Carbon has no documented internal phono preamplifier. Its manual directs the user to a cartridge-compatible PHONO input or a separate phono stage before an amplifier's line input. The observed U.S. package includes a Sumiko Amethyst, which Sumiko places in its moving-magnet Oyster family. That means the ordinary system path is an MM-compatible receiver PHONO input, or a standalone MM stage. Line-only powered speakers need that external stage before their LINE input; passive speakers also require a power amplifier or receiver. The deck's RCA leads are not line-level merely because the plugs look familiar, and the grounding instruction should be followed for the actual receiver/stage.

There is no built-in PHONO/LINE switch or speaker amplifier to simplify the system. If your current receiver has a PHONO input, verify that it is MM-compatible and that you are not adding an unnecessary second phono stage. If you use powered speakers, account for a separate stage as part of the installation rather than expecting the turntable alone to drive them.

Manual belt drive with a distinct arm design

Pro-Ject describes a manual two-speed belt drive with an outboard motor. The manual specifies motor switching and manual transfer of the belt between pulley steps for 33⅓ and 45 RPM. The inspected documentation does not list 78 RPM, automatic arm return or an end-of-record platter stop. Cueing and record-end handling remain a manual task; a motor on/off switch is not a record sensor. If you require auto-lift or auto-stop, ask about the exact version and do not buy based on an assumption. This configuration is not fully automatic.

The manufacturer identifies a 9-inch cc EVO carbon tonearm, with a 230 mm effective length and 8 g effective mass in the information sheet. The package's cartridge is the Amethyst MM; the manual's general installation guidance does not establish cartridge-specific tracking-force values for that U.S. pairing. Follow Sumiko's current cartridge instructions and verify alignment/setup support if this would be your first manual deck. The product sheet lists a 300 mm platter, but its material conflict makes that an unresolved purchasing detail. Buyers for whom platter construction is decisive should ask Pro-Ject or the seller to identify the exact production revision and obtain a reliable model-specific answer.

Footprint, mass and the optional cover

The product sheet lists 430 × 150 × 323 mm, roughly 16.93 inches wide, 5.91 inches high and 12.72 inches deep, with 8.0 kg net mass. This is the published body footprint only; allow extra room for cables, arm movement, controls and any lid. Pro-Ject calls the lid optional. The exact U.S. item identity does not prove that a dust cover is in the carton, so confirm package contents instead of assuming inclusion. The larger mass also matters when moving the table or placing it on furniture that must support the full load; the specifications do not tell you whether a particular shelf is sufficiently rigid.

The U.S.-facing source set now includes Audio Advisor's Gloss Black / Amethyst package plus separate Acoustic Sounds Black, White and Red Finish / Amethyst item records. Acoustic Sounds identifies these with its own seller Product Nos. T RPM5CB, T RPM5CW and T RPM5CR; none is a Pro-Ject part number. The maker lists black, red and white high-gloss finishes for this RPM 5 model, and the seller pages describe the same cartridge package and two-speed manual drive. No functional difference is documented across these finish records, so this assessment covers them together rather than presenting color listings as extra models. Confirm the selected finish, cartridge and carton contents on the exact offer. The pictures below show item-page appearance only; they do not establish platter material, hidden setup values or included accessories.

Observed finish variants

All three Acoustic Sounds item pages name the Sumiko Amethyst package and present the RPM 5 Carbon's same two-speed manual belt-drive configuration. The separately checked Red Finish page is an exact seller record; it does not establish current stock, carton contents or a new operating capability. The pictures cannot settle the manufacturer sheet's platter-material conflict. Treat color as a finish choice, then verify the exact seller item and package before ordering.

When it belongs on a shortlist

Consider the RPM 5 Carbon if you want the observed Amethyst MM package, already have a compatible MM phono path or plan to add one, and accept a manual table with a belt transfer for 33/45 RPM. It is not the easy choice for a line-only speaker setup without an added stage, an automatic-operation requirement, a 78-RPM collection, or a buyer unwilling to verify the platter-material discrepancy and cover contents. The open design, arm specification and extra weight may be relevant to an enthusiast comparing manual decks, but none is evidence of superior sound in the absence of testing.

Before buying, confirm the exact Gloss Black / Amethyst configuration and cartridge condition; verify the MM stage compatibility; ask the seller to resolve the platter material for the exact unit if it affects your decision; check whether an optional lid is included; and compare the 16.93 × 12.72-inch body to the available shelf with clearance added. The archive does not support a current price or stock statement. Those package and system checks are the practical basis for shortlisting this model.
