The Kora PR140 preamplifier delivers a smooth, precise musicality with natural dynamics and lifelike detail retrieval. Designed to respect the integrity of every recording, it comb ines refined control with exceptional transparency. Beyond standard functions like volume and balance, the PR140 also allows you to fine-tune and balance the level of each of its five inputs, adapting perfectly to any system. What makes the PR140 stand out is its modular design. With an extension slot, it can easily be upgraded by adding optional modules such as a phono stage (for vinyl playback) or a DAC (for digital sources). This flexibility ensures that your preamplifier can grow with your system and remain future-proof. Built with premium materials and Kora’s dedication to craftsmanship in Toulouse, France, the PR140 is a versatile centerpiece for serious music lovers seeking both precision and upgrade potential. Key Features AKM Upsampler – Upsamples the CD signal to 768 kHz, pushing conversion artifacts out of the audible band. Precision Synchronisation – All digital clocks remain locked to the original CD signal for superior timing accuracy. ROHM DAC Conversion – 32-bit / 768 kHz conversion ensures exceptional resolution and detail retrieval. Square Tube® Technology – Provides smooth, natural, and dynamic musicality without amplitude limits. Pure Analogue Output Filter – Maintains phase accuracy, delivering a wide and three-dimensional soundstage.
