RCM AUDIO THERIAA AUDIOPHILE PHONO PRE-AMPLIFIER MC/MM

 

The THERIAA phono preamplifier is the result of many years’ research and development in the domain of sound reproduction from the analogue turntable. The experience we gained in building the Sensor Prelude IC allowed us to launch the THERIAA project and explore new and unique strategies to test the limits of what is technically possible. All elements of the design were thoroughly evaluated and tested before being deemed fit to be used in THERIAA. The resulting sound quality is testament to the painstaking work that went into the design. 

The components used in THERIAA are sourced from only the “best of the best” companies including Elna, Sanyo, Nichicon, Wima, TDK Epcos, Vishay, Burr-Brown, Analogue Devices and many others. All components are measured by hand, graded and then selected so that matched pairs are always used in the circuits. This ensures that the left and right channels are in perfect symmetry.

Any amplifier can only be as good as the power supply that feeds it. THERIAA uses a completely separate power supply housed in a strong aluminium case and connected to the main unit by a high quality shielded cable with Amphenol connectors.


The signal amplification circuits of THERIAA are fully balanced and will benefit from receiving a balanced input from the phono cartridge. The unit will work very well with a single ended input from the cartridge but if connected in balanced mode the noise floor will be lower resulting in superior dynamic range.

Adjustment of the input impedance, level of gain and input mode (balanced or unbalanced) is regulated by high quality Omron dipswitches easily accessible on the rear if the unit.

The expression “the whole is greater than the sum of the parts” applies to THERIAA very well. Whilst every individual part is selected and manufactured with meticulous care, the overall result exceeds expectations. If you want a neutral, transparent and easy to use phono preamplifier that performs at the highest level, then THERIAA is it!
