What a privilege to experience the Octave HP 700 SE preamplifier and MRE 220 SE power amplifiers with Super Black Boxes at home for several weeks.

In this hobby, everything revolves around harmony. You never listen to a single component – it’s the chemistry between amplifier, loudspeaker and room that makes the difference. And here, something special happened: a natural synergy between Octave and the beloved Graham Audio loudspeakers. Music Maestro!

After fifty years of passion for music and countless system combinations, I know how rare it is when technology and emotion truly unite. Most setups sound good, some excellent. But every once in a while, something unexpected happens – something that touches the soul of music.

You can compare specifications and discuss theory, but in the end there’s only one truth:
“The proof of the pudding is in the eating.”

This Octave combination moves, inspires, and connects. It transcends bass, midrange, and treble — here, the music awakens.

Even after fifty years of passion for high-end audio, I feel that same fire rekindle.
The team from Karlsbad has once again thrown coal on the fire — and how!

– Ron, Callas Audio (Lelystad)
