MRE 220
The newly designed MRE 220 mono power amplifier is based on the ultra-reliable MRE 130 and the award winning RE 290 models. The RE 290 was designed for the newly developed KT 120 power tube. This model won the prestigious Golden Sound Award from Hifi Magazine Stereo Sound in Japan and is used as a reference amplifier by many editors. The MRE 220, Octave’s second amplifier designed for the KT 120, achieves a performance that was previously deemed impossible with tube amplifiers with the KT 120 and its new Power Supply and Output-Transformer-Section designs. The output power climbs up to 220 W RMS into 4 Ohms with 300 W Impulse Power. Just to mention a few key specs: The Power bandwidth at full power ranges from 20 Hz up to 70 kHz. The amplifier is stable down to 2.5 Ohm speaker impedance and the S/N ratio is higher than -116dB. The input section can be optionally equipped with a Balanced Input Transformer. Such an Input Transformer eliminates effective ground loops and high frequency noise on the ground line which can affect the sound.
