Pro-Ject RM5.1SE Turntable
The aim to better the hi-fi -classic Pro-Ject-1 is achieved with two different approaches: According to the principle of "less is more" we exchanged the rectangular chassis in favour of a radical "drop-form". In addition, the old resonating main platter was exchanged for MDF which is free of resonance. A metal ring is mounted around the main bearing for optimised conductance of unwanted vibrations. The audible benefi ts are amazing. The sound is calmer and richer without losing detail.
Pro-Ject RM5.1SE Features
Chassis piano-lacquered dark grey
A quiet running AC motor with a two-step pulley drives the hub and platter via a flat-ground belt.
The medium density fibre plinth stands on three height-adjustable rubber-damped aluminium cones.
The motor is decoupled from the plinth to reduce vibration transmission.
MDF platter with integrated vinyl mat
The platter's low-tolerance chrome-plated stainless-steel axle runs on a Teflon bearing plate in a sintered bronze bearing housing.
Central metal block optimises centre of gravity and damps main bearing.
Connection to the phono input of the amplifier can be made with connecting cables of your taste through the gold plated phono sockets and earth screw. A standard cable is provided.
External power supply avoids potential electro-mechanical interference.

Tonearm 9cc Details
The headshell and armtube are fashioned from a single piece of carbon-fibre.
Conical armtube avoids standing wave reflections.
Inverted tonearm bearing comprises four hardened stainless tips in ABEC7 spec ballraces.
Rings provide very solid arm bearing housings. The outside ring is open to avoid resonances.
Design of counterweight effectively counteracts unwanted resonances.
The counterweight supplied is suitable for cartridges weighing between 6 - 10g
Counterweight shaft lowered to record level reduces cantilever forces and dynamic wow when playing warped records.
Solid armbase permits accurate height adjustment of armtube and VTA (vertical tracing angle).
Single-screw fixing of armtube allows rotation for easy adjustment of needle azimuth despite fixed headshell.
Silicone-damped armlift can be adjusted to suit working height of the arm.
The internal wiring consists of flexible high-purity copper from the headshell right through to the gold-plated phono sockets.
