Octave MRE 220 SE Power Amplifier

After eleven years, and after extensive technical development projects at Octave, it was time to further adapt the MRE 220 mono power amplifiers - the rock in the surf - to the higher demands of modern loudspeakers. Long listening sessions led to the solution of an adjustable damping factor. The new MRE 220 SE damping factor can now be flexibly adjusted to ideally suit the respective speaker - resulting in rock solid reproduction quality with virtually any loudspeaker.
