Product Description
Jeff Rowland Corus Pre Amplifier delivers exceptional levels of transparency, noise-free musicality and has an excellent reproduction of music even at low levels. This preamplifier delivers a groundbreaking AC power supply, boosting the signal so it is ready for further processing.
3-Dimensional Sound
Jeff Rowland products are renowned for their high quality performance. The Corus pre-amplifier displays the brands passion and expertise in manufacturing top class audio components It delivers low noise pollution, less grain and improved levels of transparency. This all results in an extremely spacious, three dimensional soundstage where each instrument and vocal can be enjoyed in absolute clarity and precision.
Dynamic Performance
The pre-amplifier yields a broad frequency response with superb bass definition, harmonic reproduction of the mid range and sweetly detailed treble. This is the best pre-amplifier from Rowland yet, with amazing details showcased in the low levels and impressive micro dynamics. The Corus also takes complete authority, delivering speed and breathtaking macro dynamics, resulting in an absolutely superior listening experience.
Corus Technology
Excelling in sonic performance and musicality is down to the Corus's advanced technology. It has a completely balanced topology and is housed in an aircraft grade aluminium chassis with delicate audio and control circuits. The power supply is isolated in separate systems for absolute shielding to RFI and EMI. Alongside this, ceramic board circuits are used for minimum energy retention. All these components work beautifully together to give the pre-amplifier the dynamic performance it provides.
