MRE 130

About the MRE 130

The Octave MRE 130 monoblocks are push-pull power amplifiers in pentode configuration, producing approximately 130 watts into 4 ohms (140W at 2% THD). They feature a unique power management system that controls heating and supply voltages to extend tube life and maintain consistent sound quality. The amplifiers include an electronic protection system to safeguard against tube failure and other faults. The MRE 130 uses a novel enhanced pentode output stage with a separate power supply for the pentode mode, improving sound quality and engineering performance. They have a frequency response of 10 Hz to 80 kHz ±0.5 dB, total harmonic distortion below 0.1% at 10 watts, and a signal-to-noise ratio greater than 100 dB. Inputs include 1 x RCA and 1 x XLR, with two loudspeaker outputs. The amplifiers weigh 22.7 kg each and come with accessories such as a power cable, a 3mm screwdriver for bias adjustment, and spare KT88/6550 tubes. The MRE 130 is praised for its ability to reproduce a large orchestral scale with dynamic detail, rich voices, and raw emotion, making it suitable for high-end audio systems.
