RCM Sensor 2 Phono Preamplifier

RCM Audio, a boutique Polish manufacturer with just three high-end products in their range, have released the RCM Sensor 2 phono preamplifier, now available in Australia via distributor, Puremusicgroup.

RCM Sensor 2 is an extensive upgrade of the giant killing and widely acclaimed Sensor Prelude that audiophiles have embraced with enthusiasm for its excellent sound quality and value for money.

Improvements over the Sensor Prelude include:

  • Power supply is larger and outputs DC instead of AC
  • More capacitors in the PS for better stabilization of the current flow
  • Improved circuit design and layout
  • Higher quality IC's, Resistors and Capacitors
  • Theriaa style casework with no visible screws and low resonance design
  • More cartridge loading options
  • Improved grounding terminal

The RCM Sensor 2 phono preamplifier provides precise RIAA equalisation for cartridges in the range of 0.3 mV to 5 mV, and outputs a line level signal of 2 Volts at 1 kHz. Easily accessible switches on the back panel allow the user to adjust cartridge load impedance, gain and mode of input stage (balanced or single–ended).

RIAA equalization is achieved via a passive split network with two separate RC filters, low noise resistors and 1% tolerance polypropylene capacitors. To ensure high precision in the RIAA equalizer each component of the filter is hand picked and measured to guarantee a tolerance of less then 0.3 dB in the frequency range 20Hz – 20 kHz. This is done for every unit built so that the customer receives a unit sounding as good as the reference unit in RCM's laboratory.

RCM Sensor 2Because of the extremely high gain capability (up to 76dB) combined with a very low noise floor, theSensor 2 can amplify very low output MC cartridges with ease. According to RCM AUdio, music emerges from a black background and images are finely crafted and spread out before you in a sound stage that is both wide and deep. Detail retrieval is exceptional and the ability to communicate Pace, Rhythm and Timing (PRAT) is very satisfying.

Warwick Freemantle, Managing Director of Puremusicgroup told StereoNET:

Our best selling phono pre-amp, Sensor 2 performs at such a high level that it can be used in the most expensive audiophile systems, however its very reasonable price allows music lovers at all levels to enjoy the superb sound it produces.
